You can tell by the modified, enlarged palpi. It is a member of the family Oecobiidae. Most likely, depending on where you live, either Oecobius navus Blackwall, 1859....................Cosmopolitan or Oecobius cellariorum (Dugès, 1836) *....................Cosmopolitan The species are quite common indoors, often in a distinctive kind of web near window frames. Web consists of 2 thin, silken sheets connected by some silk lines radiating from the sheets to act as trip lines. The spider lives between the two sheets, residing on the lower one. Webs can be along window frames, ceilings, walls, floors, sort of edges where structures come together. The common name is flatmesh weavers. Has a cribellum (in front of spinnerets) and anal tubercle with a brush of special bristles that aid in spreading the silk from the posterior spinnerets as it encircles prey. It has a distinctive shape to its body and leg attachment and display. Distinctive looking cephalothorax, eye structure and arrangement. Prey capture behavior very interesting. They often feed on ants. Have you seen booklice in the webs?

We find them in an area that tends to have higher humidity and a (slowly decreasing) population of psocids. We'd like to find out more info about this spider - if it's specifically drawn to humidity or psocids, or if it's an indication of some other, as-of-yet-undiscovered issue. Thanks!
