I am always keeping an eye out for turret due to my interest in dwarf tarantulas.
I often see these turrets that have this lacy webbing and decided to investigate.

Another one.

Here is the occupant that I flooded out. Common spider but handsome, plump fellow.

Excellent pictures, Miss June!

I always wondered what the inhabitant of one of those laced-over burrows would look like. Plump indeed

Food is plentiful this year but don't know if that plumpness is bugs or eggs.

BTW any one ID this spider? I am a T person although other spiders are growing on me.

That is very cool, June.

Hi June-

Looks like a Kukulcania to me, maybe K. arizonica or K. geophila? They have a special structure on the underside called a cribellum that they use to "fluff up" the silk to create the distinctive webbing. They're known as "crevice spiders" because they usually build their silken tube homes in existing cracks and holes. I wasn't aware they actually dug burrows, although it's possible that one has moved into an abandoned burrow made by something else.

They're neat spiders, actually. They live longer than some tarantulas (although probably not our desert natives!) and are one of the few (maybe only???) araneomorph spiders where the females continue to molt after maturity. I have one K. hibernalis that's lived in a jar for 7 or 8 years now on nothing but a cricket a month!

Thanks for the ID and other info Wade . Very interesting. I am almost certain that the ones here do build a turret. Two reasons. First I find them in turrets all the time which are shallow enough that spider will easily flood out. Tarantula turret burrows are deep enough and soil so porous here that can pour water down one all day and won't flood anything out. More compelling is that burrow in first picture started out as hole with lace around it and then turret developed over several days. It also was < 4" deep. Not proof but close.
