Caught 7/5 in El Paso, Texas, US, sidewalk of suburb in desert area. I suspect/hope crematogaster?

That does not look like Crematogaster to me. It looks like Solenopsis invicta, which would be very likely in that location.

Definitely a Crematogaster sp. Would need microscope to tell exact species.

If you want ID requests to be looked at and respected by more people, please follow proper formatting as obviously put at the top of the request thread.  Many will not and do not trust outside links.

Sorry I was posting from a phone and it wasn’t working like I wanted. Will try to post form a computer next time. Thanks!
Also thanks for the iD help! Which parts of the ant would help tell you which species? On the off chance I get a decent enough picture to tell

Actually, looks like Solenopsis invicta. When did you find her? If you found her after sundown, she is probably Crematogaster.

You should kill the Solenopsis invicta you find.  They're a highly invasive species and will most likely be too difficult to care for as an early ant keeper.

I disagree. You should not kill them nor help them. Leave them alone if you are not capable of handling a colony of these. They are invasive, yes, but last time I checked, we are too. ;)

They should be killed and should never be helped.  The least you can do is take them out of the wild, but if inexperienced, killing is better than raising a colony that will escape.  

 

We are invasive, but also intelligent.  The least we could do is help the ecosystem out as much as we can.  And yes, humans dying is probably the best thing overall for the ecosystem.

Maybe something's wrong with my ID skills but isn't that how Crematogaster's petioles are attached to their abdomen? Like the defining feature is the petiole being attached to the top part of the abdomen

Most Solenopsis I have seen have this too. The most defining feature of Crematogaster is the heart shaped abdomen and the circular head.

Ah. I thought it was a Crematogaster specific thing. And the angle of the images could suggest a pointy abdomen, just out of view.
