Reclusive spider - Badumna longinqua

Reclusive spider - Badumna longinqua
Alameda County, California, USA
March 26, 2010
Size: ~5-6 mm
This spider is so shy of disturbance that I couldn't photograph its whole length. Never seen in daylight; photo taken at night. It lives in a crevice above a metal bracket where a garden-hose nozzle is hung and makes a web every night that covers the nozzle. The pyramid-shaped web extends downward from the crevice and consists of approximately vertical, but flaring, threads connected by short threads zigzagging between them. The short threads are double; the spider used two spinnerets at once or else backtracked. The spider looks gray and downy in real life, less so in photos.

Another Badumna Longiqua, I believe
What you described, as well as what is seen in the photos, is a "cribellate" web, which is what this species builds. They have an extra spinning organ called the cribellum which helps them make the messy webs.

 
I was afraid of that
Not another one of those! This spider looked different in dorsal view from the known B. l.s here, and its web looked different from most of their webs, and it reacted very differently to being found. I hoped for another species.

Many of the B. l. images are from my yard. Adding more establishes only that they're in the same location all year. Are there too many yet? Any suggestions on culling?

 
Haha, I know what you mean...
...I keep finding tons of Tegeneria around my property. I would say go ahead and add these images to the B. l. section. They're nice photos and they show the cribellate webbing better than the other images already there. I wouldn't worry about deleting any of your submissions right now. I think they each have something a little different (i.e. the color shades, etc.) that they bring to the table. Of course, that's only my opinion... not sure what everyone else thinks.
