Natural History, Phenology & Image(s)

Feeding Guild: space web builders
Feeding guild when noted defined by Uetz, G. W., J. Halaj, and A. B. Cady. 1999. Guild structure of spiders in major crops. Journal of Arachnology 27:270-280. PDF
Recorded Habitats: Low in the canopy of shrubs and trees.
Life & Natural History: Space-web attached to branches some four feet above the ground. Web tends to collect dead curled-up leaves, which are often used by the female as a retreat and a place to fix their egg-sacs. These egg sacs are a brown paper-like texture and hang from a short thread (Hancock, pers. obs.).
