Sawdust in a Uloborid Web

Wednesday, June 25, 2008

Spiders in the family Uloboridae make some of the most delicate of all spider webs, so delicate in fact that an automatic camera usually looks past the spider, through the web, and focuses on something unimportant in the background. Today, however, cutting plywood left a dusting of fine particles on this female's (probably Uloborus diversus) artwork. That is her, just above and to the right of center, hanging upside down, long front legs bent at the joints but held together to make her look like a sliver of bark. She is among the most harmless of all spiders, a finely-crafted work of art, obvious only in those moments when dust has just fallen and the light finds her from a perfect angle.
