Entertaining Myself outside the US Embassy

Sunday, July 03, 2011

One nice thing about the hobbies of entomology and botany is that they can be indulged almost anywhere.  These two weeks I have been traveling in Brazil.  We’ve had many little adventures, but our big one was a road trip to the US embassy in Brasilia to register the citizenship of my youngest grandson.  The three-hour drive is pretty, but we arrived late by approximately the same amount of time it takes to clean up after a car-sick three-year-old.  Then, the embassy security personnel considered it excessive that the registration of one infant should require the admission of seven people, even if each of the siblings, parents, and grandparents carried US passports.  My son—very good in a crisis—managed to negotiate for six, but the guards insisted that a line had to be drawn, and I found myself left outside as the rest of my family went in.  Thus it was that I enjoyed about 90 minutes exploring the landscaped area in front of the US and French embassies and a patch of weeds that surrounded a construction site. 

The city of Brasilia is younger than I am.  It was not laid out until 1956, by which time I was in 1st grade.  The idea was to encourage the development of Brazil’s interior by placing a new capital smack in the middle of undeveloped territory.  Today, the metropolitan area boasts over three million people, but its recent agrarian past was evident in the Brachiaria that dominated all of the non-landscaped areas.  This part of Brazil was largely settled by immigrants from Germany and Italy, but the Brachiaria came from Africa.  Brought in as high-protein forage for cattle, it has pushed out the native flora.
 
As is often the case, the field of Brachiaria had also become home to several hills of leaf-cutter ants, probably Atta cephalotes.  I found a column of these ants moving up and down a young mango tree, but they weren’t moving any cargo.  I have seen them, overnight, strip the leaves from a bigger tree than this one, but perhaps these workers, like me, were simply out for a late-afternoon stroll while the rest of the family did something inside the embassy.

Several kinds of butterflies flitted about the Brachiaria.  The sun was too low and the individuals too skittish for me to get many pictures, but one black and white skipper sat still while I manipulated my lens within about five inches.  After several days of research I am convinced it is the Tropical Checkered Skipper, Pyrgus oileus (sometimes seen as P. orcus), on a Lilac Tasselflower, Emilia sonchifolia.  The P. oileus caterpillar feeds on Malvaceae (like cotton or mallow), but the adult likes the nectar of Compositae, like this Emilia (an immigrant from either Africa or South East Asia).
 

Next I investigated a long wall heavily colonized by the Brown Widow Spider, Latrodectus geometricus.  Each of the females rested under a little awning; so that I wasn’t sure what I had I dislodged one.  The one male I saw rested out front in a web more condensed and full of trash than the Black Widows we have in California.  The egg sac is also distinct, covered with little bumps.  I captured one female to use later for studio portraits.


The landscaped areas in front of the embassy have several short palm trees.  I gave each some careful inspection, in hopes of finding a jumping spider, but instead I found this wasp nest.  It was now late enough that the wasps—possibly yellowjackets—were inside for the night.  I was happy to leave them there.  I photographed the nest from several angles, which prompted a visit from the embassy security guard, who reminded me politely that I was not to point my camera at the embassy itself. 

I moved on to a tree that offered peeling bark and found my jumping spider.  It was probably an immature Menemerus bivittatus, the Gray Wall Jumper, a pantropical species I have seen in several countries.  Later, on a dead tree, I pulled back some bark and had an adult disappear into the grass before I could get a good look at her, but from a small nest I began to see hatchlings escaping.  I suspect these were also M. bivittatus, and added a couple to my collection for later filming.
About this time my family reappeared, my grandson registered in time to celebrate his first 4th of July.  However, before we left Brasilia, we took a drive through the downtown, including a pass around three sides of the congressional building (Palacio do Congress) and one corner of the presidential office (Palacio do Planalto), the supreme court, and the national cathedral.  That’s the nice thing about having travel as a hobby, it can be indulged almost anywhere.

Open-air Arthropodarium on a Charlotte Corday

Saturday, June 25, 2011

School is out, so it's catch-up time here at Capers. All the thoughts and observations that I've carried around since things accelerated in March can finally find a place to land.

In the few minutes I could snatch here or there over the last couple of weeks, I’ve been enjoying a hedge of passion vines and grapes that I started last summer. Over the winter, I covered (and saved) some of the passion vines with clear plastic, and learned a lesson from what I never got covered. A freeze came on suddenly just before Thanksgiving. Then the winter turned mild but wet. The rains continued longer than I can ever remember. I covered a length of about 16 feet (8 to 10 feet high), but I never quite got the plastic as far as the P. amethyst. It survived the worst cold and still had green on it until almost the end March, but then it died. I have since read that some prefer dry ground when it is cold. I replaced the dead one as soon as Lowes put the spring vines out, and next winter I will cover it.

The section I protected included the bright red P. vitafolia, the maracuya-bearing P. frederick, and what the big-box home-improvement center had labeled as P. victoria (which is lavender), but turns out to be one of the whites, either ‘Charlotte Corday,’ or ‘Constance Elliott.’ Until someone corrects me, I will go with the former, named for the ‘Angel of Assassination’ who went to the guillotine for stabbing-to-death Jacobin leader Jean-Paul Marat in his bath-tub. She hoped it would end the Reign of Terror. In actuality, it turned them each into martyrs, one for each side, but among Reign-of-Terror floral remembrances, this flower stands out as perhaps the most delicate. As a history teacher, it’s hard to imagine planting anything in my yard with more history than that.

The white one has been blooming for a couple of months, and has set dozens of fruit. The vitafolia and frederick just began blooming last week. The primary pollinators for passion flowers are bumble bees. In our area, that’s the Valley Carpenter Bee, Xylocopa veripuncta. I see them mainly in the late afternoon, most often two of the black females, and occasionally a single tan-orange male. He seems mostly to be checking things out, and I don’t see him land anywhere. They don’t seem to mind either me or the camera, and when the females are intent on a flower, they let me approach within four or five inches.The bees are just the right height to brush under the five overhanging anthers, picking up pollen on their backs, and carrying it to deposit against the three stigmas. They seem to prefer the whites, visit the frederick only after several visits to each of the available white blossoms, and show no interest at all in the vitafolia.I first encountered an insectarium at the Berlin zoo, misnamed though, because it housed and displayed both insects (I saw my first walking stick) and spiders (I saw my first Argiope). Spiders are not insects, but both are arthropods. A better name for such a display therefore is "arthropodarium."








In early June, I began seeing a California Hairstreak Satyrium.












A week later, the first Gulf Fritillary arrived.
















The Argentine Ant tends to dominate my yard, but so far I have not seen them tending herds of scale insects.

So far, I have seen four species of spiders in my hedge.


Holocnemus pluchei immigrated into our area in the 1970s, but now is ubiquitous.



Cheiracanthium mildei needed no introduction: It was already everywhere.







Of the spiders that show up as hedge residents, my two favorites are jumping spiders (family Salticidae). The male Thiodina hespera took exception to being photographed, but I will have the rest of the summer to get a clearer picture. This was the species that first attracted my attention and launched my interest in spiders, some 37 years ago, so we are old friends. Back then, using my first set of close-up lenses, I took my first spider pictures and sent them off to a scholar studying this genus. In those days, the species had no name, and I heard recently that the specialist considered naming the species after me. I don't think my little investigations would have justified that, but it helps explain why I consider this Thiodina almost a member of the family.









The second jumping spider was a female Sassacus vitis. She appeared just after a microscope I had ordered arrived in the mail. She thereby won the right to be my first subject under the new apparatus. On a leaf, her iridescent scales would catch the sun and cast a glint of golden bronze. She is loose again on my hedge, and I will try again to catch a picture of that glint.

The summer and my hedge are still young. I will be traveling some, and trying to write for a portion of each day. But my microscope is brand new, my arthropodarium is just beginning, and school doesn't start for another eight weeks. Life is sweet.

A Passion for Passion Vine

Saturday, September 18, 2010

One of my delights this past month has been a new hedge of passion vine along my back fence. My impetus was new construction on the vacant lot behind us: I wanted some quick privacy. Since I had developed a fondness for the genus Passiflora while living in South America, I decided to try several species, some for their spectacular flowers, some for their fruit (a "sweet granadilla" and the sour "maracuya") and one for its cold hardiness.The first to bloom has been this P. vitifolia. The blossoms last only from sun-up to sun-down, but new ones appear almost daily. So far, none have set fruit, even with my attempts at hand pollination, but I’ve noticed a sudden influx of hummingbirds, fritillary butterflies, and even a swallowtail. Such fun.

Over Thanksgiving I received an early Christmas present that not many readers of this blog will have on their wish lists. For me, however, The Spiders of China sits at the intersection of several personal interests: I am a bibliophile, an aficionado of fine spiders, amateur sinocologist, and I get my thrill-of-the-hunt from tracking down those little pieces of information that no one else seems to care about. I am also the man who has everything (as of today, even a new grandson). What else is left to get me?


I obtained my first foreign-language spider book in 1976, when I mastered enough Italian to go into a Rome book store and ask, "Dove si trova un libro di ragni?" From our Berlin stop on that same trip I brought home Leben am seidenen Faden: Die rätselvolle Welt der Spinnen. Colombia and Brazil share a paucity of spider books, but many of their species show up in the well-done Arañas de Chiapas, my trophy from a trip no farther than Tucson.


Thus, in 2004, when I was preparing to visit China, one of my first activities was to make a list of books I wanted to find. Amazon didn’t know these books existed, but I found The Spiders of China on the web at China Scientific Book Service.


Silly me, I figured it would be easier, more fun, and maybe less expensive to actually buy the book in China. (I also seem to recall some problem in getting the website to accept an order.) With that goal, in Shanghai, I made a visit to the largest book store I have ever seen, four or five stories high, with hundreds of thousands of books on display . . .










. . . but not The Spiders of China. I consoled myself with a thin paperback on the insect pests in sugar cane.


Later in my trip, I was more successful with another book on my list, not just finding The Edible Insects of China, but meeting author Chen Xiaoming, and getting an autographed copy. Yet I had to come home without The Spiders of China.


Nor was I able to find a copy during my short trip to Zhejiang in 2008.


However, what I did secure in last year’s trip was familial connections in China. I’m not sure how they managed the trick (one does not ask those details about a gift), but the gist of it is, I now have my copy of The Spiders of China.


From the introduction, I learned the Chinese word for Spider (蜘蛛 zhīzhū) means “knowing to kill the bad element.” That makes sense. I also learned that spiders have appeared in Chinese literature since about 1200 BC; and that my own favorite family, the jumping spiders (Salticidae), first drew mention in 1756.


I bonded with the Salticidae about 35 years ago, watching one explore a terrarium. They move with the studied concentration and graceful control I later saw on the streets in China, where Tai Chi enthusiasts exercise amidst passers-by.


Opening the new book, my first hope was to identify a Salticid I photographed on the campus of South West China Normal University, Beibei, Chongqing, where I taught English the summer of 2004.



Drawings in the book helped me quickly settle upon the genus Harmochirus (Wikipedia lists nine species, from Africa to Japan), for which the book offered two, H. brachiatus and H. insulanus.



A quick web search suggested my spider looked more like brachiatus, but also disclosed two new species described since 1999, H. pineus and H. proszynski. I discovered that the Chinese arachnologist most familiar with Harmochirus was Dr. Li Shuqiang, so I sent Dr. Li my photographs. He graciously confirmed both the identification as Harmochirus and my fear that these photographs would be insufficient for identification of species. The fact is, within a given genus, most species of spider can only be distinguished by the shapes of their genitalia. For this reason, The Spiders of China devotes some 300 pages to drawings intended to serve researchers who have specimens under the microscope. Alas, I took only pictures (see also this Nephila) in China, and preserved no specimens.


The other 330 pages, however, give a very useful introduction to the 56 families of spiders in China (a few of which are unfamiliar to me in America), and to their genera, for which a photograph is often sufficient for identification.


To which many readers may be thinking, “So what?”


Many years ago, at the end of a school year, our principal roasted the teachers with funny awards. Mr. Hollinger dubbed me the “Staff Obscurantist.” As I’ve thought about that over the years, I’ve concluded he hit the nail right on the head. I’ve spent my life intrigued by a long list of things that would interest few other people, whether in history, linguistics, botany, zoology, or anthropology. In the process, I’ve come to realize my unique challenge as a writer: steep myself in the obscure from a dozen different fields, and distill from them the details that can embellish a story and open up the subjects to readers who would otherwise not care.


To those of you who have read this far in a review of The Spiders of China, may I ask, “What kept you reading?”

Canon PowerShot SD1200 IS: a product review

Tuesday, June 23, 2009

I was slow going digital with my photography. As late as the summer of 2000, I dragged forty roles of slide film and my Nikon SLR for seven weeks across Europe and Uzbekistan. I still hadn’t organized and viewed all those slides when I bought my Canon G3 during the summer of 2003, and now, of course, when I want to use one of those European shots, I first have to digitize it. My G3 has been twice to China and twice to Brazil. It has recorded weddings for my five children, gotten me nearly three years into grandfatherhood, and illustrated these first five years of Capers with Carroll. On a single day in Yunnan, I shot 600 keepers from a bus window. In Pernambuco, I captured 120 images of one male Frigga sp. to get the picture I use at the top of this blog. That would have been a prohibitive four 36-shot rolls of film. I love my G3.

However, in September, I spent some time in the camera section of a big-box electronics store, helping a visitor from China choose a pocket-sized digital. Suddenly the G3 felt pretty bulky. My favorite shirt is a guayabera with four pockets. They will hold the G3, but it’s awkward to maintain for more than a few minutes. I usually carry my camera on a belly strap, but that creates other problems. Whether I’m photographing urban wildlife or grand kids, the key to success is to have the camera perpetually at hand. Even as a junior high teacher, whether I want to record evidence against a graffiti artist or a cute candid shot to forward to the yearbook, a camera in the pocket is worth two in the closet.

So Friday I bought (and my wife credited to Father’s Day) a Canon PowerShot SD1200 IS. Consumer Reports had rated it their top choice and Staples offered a good deal.





As the photographs show, it passes the grand-kids test. Natu and I were on opposite sides of a spider web. I was trying to capture an image of the too-small spider (visible as an orange-brown smudge), but the camera’s automatic focus went for the better shot.





In my first several attempts at photographing the hummingbird, the automatic focus preferred the surrounding foliage (a tough shot for any but the best manual focus), blurring the bird, before my subject did me a favor and came out to a better perch. I’ve grown spoiled by the ability of the G3’s small display to rotate out of the camera to facilitate shots from difficult angles, but the PowerShot’s much bigger display outdoes the G3 in bright sunshine. It even outlines the targets where it has chosen to focus. On the G3, the zoom always seemed to cost clarity, but I’m very pleased with the zoom on my hummingbird shots.













I’m also pleased with the jumping spider (Habrocestum sp.) and water strider shots, taken at the default full-wide angle. In each case, the critter let me get within 18 inches, and the pixel density let me crop and enlarge. For closer studies of insects and spiders, I will continue to use the even higher density capacity of my G3. For those, I fix the camera on a tripod, turn the subject loose on a leaf, manipulate the leaf to achieve focus, and record a superabundance of poses. Spontaneity is not an issue.


I’ve now taken about 300 photographs with the SD 1200. I like the quality of the pictures and the feel of the camera. Its turn-on speed and short lag-time on the shutter are big improvements over the G3. Even with a protective case, it fits so comfortably in my pocket that I foresee keeping it with me most of the time.

I present to you the new workhorse of this blog.

Nature-Walking with Natu (In Lieu of a 25 Things List)

Sunday, February 08, 2009

As a dedicated fadoclast (for example, I have never watched a Superbowl), I will not be doing one of those Facebook 25 Things Lists, though I have been tagged twice. I don’t foresee enough time for making lists anytime soon. I have my thesis due to the committee in ten days, an important speaking engagement (sidebar) next month, a daughter’s wedding in early April, the daily-ness of teaching junior high, and a myriad of unexpected demands on my time. Take today, for example. I brought the love-of-my-life to L.A. so she could spend a day with our soon-to-be-married daughter and take advantage of Disneyland’s current offer of free entrance on a birthday.

In L.A., I have a son attending seminary and two grandsons. By watching the eldest for the day, my son could get off for some research for a paper he has due. For me, the height of delicious decadence is a bug net, an expanse of foliage, and maybe a child or two to share the discoveries. (I’ve never met a youngster who couldn’t get excited about a bug net. That’s an experiment I’ve conducted on three continents.)

Catching bugs has nothing to do with my employment, or getting my novel written. It is totally frivolous. I constructed my first bug net when I was 25, after graduating UCLA with no more biology than the lower division Intro course. That’s why it tickles me that my little bug-net excursions find occasional mention in the scientific literature, like this one in the journal Biota Colombiana. (See pages 2 & 3, and Tatepeira carrolli listed on page 5.) I even had the privilege of editing the English abstract (not yet on-line) for the Chinese PhD. thesis from which this gallnut article was taken.

With all this as background, this morning Natu and I took off looking for some spiders. Unfortunately, it was chilly and damp, and the spiders didn’t come out to play. We had to content ourselves with other diversions.

I like to crumple fresh bay leaves and hold them to my nose. I like turning over rocks, to see what scurries away. I like watching a little boy’s eyes get big at a sow bug.

Whaddya know, I’ve said 24 random things about myself. I probably won’t finish, though. I live under a cloud of unfinished projects, but hey, there are so many delightful distractions.

Lao Papa

Saturday, August 23, 2008

At our grandsons’ ages, six weeks of development equals a full year of coursework at a major university. Sometime since our last visit, Nilo (now three months) learned to return a smile, and Natu (at twenty-three months) had both picked up names for all the other members of the family and begun to group words into phrases. As fast as I offered him new words, he took them, repeated them a dozen times, and made them his own. On a walk together, we studied the web of a Metepiera sp. in a rosemary bush and watched the spider hide under her protective tent. Then we continued on and played with Agelenids, Uloborids, and a Holocnemus in their webs. We saw a line of ants on the sidewalk and he got down on his stomach to watch them closely, repeating, “Ants, ants, ants, ants.” Then on our return trip, he ran to the rosemary bush, calling out, “Spider house! Spider house!”

This visit, for the first time, he called us Grandma and Papa.

Of course, this means I am now labeled. When Natu was born, my wife asked me what I wanted my grandchildren to call me. I wasn’t sure. It isn’t often in our culture that we get to choose a name for ourselves. I had a Grandpa Lynn and a Grandpa Howard, but somehow Grandpa Brian never seemed right. My mother’s grandfathers were Gramp (yeah, I could be a Gramp) and Grandfather (well, that might be a little too formal). I had second cousins whose grandfathers were Pa’s Pa and Ma’s Pa, which tickled me but didn’t fit me. When I spoke to infant Natu in the third person, I found myself using Papa, the same name my children called my father-in-law (though I’m not sure whether it came from Spanish or Italian, each an influence in my wife’s family). In Natu’s bilingualism, the first vowel has elongated to be a more Portuguese PAA-pa. (In contrast, Natu’s father is Pa-PA-i.). His grandfather in Brazil will have a name altogether different.

However, as my family grows, we are about to leap beyond our European linguistic influences. Early next year I expect to add a Mandarin-speaking daughter-in-law. I am very pleased with that thought. It was an early personal goal that all of my children would grow up as polylinguals and world citizens, and by the grace of God, they have. So at a new stage in life, as I have the opportunity to pick a new name, that aspect of my life could be part of the mix. I asked Middle Son how to say grandfather in Mandarin. The choices seem to be YeYe, or Lao Ye. Lao by itself is an honorific that might be used as a means of address between two longtime friends, such as “Lao Wang” and “Lao Chang,” to be translated as “Old Wang” and “Old Chang.” That kind of appealed to me. I began to think about Lao Papa.

But it may be too late. Natu already has me labeled, and the pattern he sets will be followed by all the grandchildren I hope are yet to come. And you know what? In my grandson’s voice, it sounds pretty good.

1000 Visitor! (& 1001st through 1004th)

Friday, August 01, 2008

Well, we powered it up this morning to find that while we slept, five visitors stopped by to put Capers over the one thousand mark, but none of them left the required comment to make them eligible for the big prize. Fortunately, all those who entered our contest are closely enough related to the author that they are already on the short list for autographed copies of Friday 10:03 when it is finally published.

However, if this may seem a disappointing conclusion to our big contest, our disappointment probably pales compared to that of googlers who come to Capers hoping to find the music video Itsy Bitsy Spider and instead found this. We have managed to frustrate 14 such searchers in the last three weeks alone. So, our next contest: an autographed copy of my novel (when it finally gets into print) to the one thousandth person who visits The Ittsy Bittsy Spider, thinking they'll see EliZe (with thanks to arachnomusicologist Mataikhan for identifying this artist) singing Itsy Bitsy Spider (and leaves a comment).

Bumble Bee on Ceanosis, Filistatid on Sequoia

Thursday, June 26, 2008

Ever since Vicki had to work the day I took the newly-weds to see the General Grant Tree in the snow, she has yearned for her own trip to Kings Canyon. We went today, hoping to get above smoke from the 800 lightening-sparked fires that have been burning in California. Although we got above most of it, there was still enough to obscure the tops of the tall Sequoias.

With the grand vistas muddied, I turned my attention to the small delights, like Bumble Bees in the Ceanosis. . .
