I live in northern California, but more central I guess. Sacramento. I was looking up all kinds of stuff trying to figure it out.

They are both females right?

Edit: are the white spots/eyes an indicator of anything? The adult has those. I was trying to check her eyes to make sure she was a Steatoda, but it wasn't working so well...

This is a job for.. Widowman10!!!! :D

He will be able to give you an exact ID... be patient, he'll be along shortly! :)

jsloan also is very good with ID's too!

I agree with S. grossa, but not 100% positive.

Nice pics and great find, btw! Thanks for sharing, and good luck with ID's! :)

haha, JSloan is just about 3752349X better at ID's than i am {D

i'm good with the ones i know (or the easy ones for me!). yes, these are Steatoda grossa, everyone is right. immature perhaps, as you can still see the spots on the dorsal abdomen.

also, can't see too well, but pic 2/12 looks like it might be a penultimate male (if the palps are a little swollen and it's not the angle). that picture looked a little different than most of the other pics which were of the female.

Okay, pictures 2,3,4,8,10,11,12 are the same spider (the smaller one I found) and pictures 5,6,7,9 are the larger spider I found. There are only two spiders.

I can't sleep so I went spider hunting. I found a zillion more and three egg sacks! We don't kill spiders at my house so I guess they've just been building up their population! I haven't seen any males yet though.

Edit: nevermind. I found an immature male.

Edit2: my total findings = 12 egg sacks, 2 adult female, 6 smaller ones of varying sizes/instars. I accidentally smooshed one while I was trying to catch it. I saw another female as well, but she escaped before I could get her.

All of them have happily feasted on hydei fruit flies. How often should I feed them?

if you keep the sub-adults sated, they will mature much faster. otherwise, just keep them plump. merry christmas :D

Alrighty. Will it bother them if there are uneaten fruit flies with them?

sub-adult steatoda should be feeding on appropriately sized prey. FF are too small, they should be on some crix or something. usually i dump one at a time into the cage, not tons of them.

Not the larger ones. I have some really small ones too. I tried to only put one or two in, but a few extra got in. I fed the bigger ones small crickets. I wouldn't leave crickets in with them.

I've got prey of almost every size available at any given time, so no worries. I'm only a noob to true spiders :)
