The AntsCanada Forum

California is pretty diverse but to find more and bigger species you should head to the desert in summer especially after rain or in the mountains. Species you can commonly find there: Pogonomyrmex sp, Veromessor pergandei , Pheidole sp, Myrmecocystus sp. and more. In the mountains you can find: Cam...

Yes, Argentine ants.
One of the most common urban species in Southern California.

Linepithema humile.
You should add a few workers because she probably won't survive without them.

She is probably not dead! Often Northern Camponotus do that In very cold temperatures.
Once you warm her up she will start moving again.

M. minimum is found only in North America.
She might be Monomorium or Solenopsis but without a picture of the antennae we can't say.

We will need more photos.
Some sort of Myrmicine maybe Solenopsis, Monomorium , Pheidole.

Yes, Myrmica sp but it's very hard to tell what species.
She will need hibernation before she lays eggs and needs to be fed during colony founding.
Good luck!

Yes, Camponotus sp. but it would be pretty hard to tell which without microscope pictures because there are a lot of species there.

No need to worry then, unless temperature falls a lot below zero.

I don't think change of temperature will harm her unless it gets too extreme.
What is the temperature of your garage in winter?
