So I noticed two workers under a tile when I have never seen these anywhere except arizona. I know they are extremely invasive. What do I do?

Florida and Hawaii are the only states that are known to have populations of Plagiolepis. You're likely seeing something else.

I'm sure many species in AZ, including Brachymyrmex spp. and Nylanderia spp. could be easily mistaken for Plagiolepis. How did you identify the workers?

extremely small yellow workers with a large abdomen(compared to body), sometimes see dark spots on abdomen. rounded head. smaller than local brachymyrmex.


Post a clear picture.

 

my photography skill are nill. picture would look like a yellow dot.

searched the web, only thing that looks alike is brachymyrmex, which are larger than the two workers I saw.

Can you measure them on a ruler, or collect one and put it under a microspe? One thing that might explain the size, is if they are nanitics.

Went back to the rock and they are not there. will have to keep an eye out. they were smaller than large springtails, smaller than hypoponera. Pretty sure not nanitics of brachymyrmex.

You are sure that it is not a Myrmicine, right?

no, it was not. I know what the general myrmicine looks like.

Okay, I'm stumped. Maybe it is Plagiolepis.

Consider Acropyga. I would put money that it is not Plagiolepis.

Maybe... but they were a bit more yellow, like lasius latipes yellow. Also were near the suface, not in the nest, wich I don't think acropyga do.

Acropyga epedana?
 
Totally guessing though, as I'm not good at identifying small ants like these (Without a fair amount of research).

My Active Journals:

 

Formica pacifica

Formica planipilis (Parasitic sp.)

I don't this is Acropyga. It very well be Plagiolepis allaudi. The queen fits pretty well. It is either this or Brachymyrmex depilis.

This looks like an Acropyga to me. These ants tend to have very distinctive ocellli, which are obvious even in photos of this quality.  The mesosoma is fairly "skinny" where it attaches to the head, which is another distinctive feature of this genus. Neither of these features are necessarily characteristic of Plagiolepis.

 

When you found her, did she have anything in her mouth? Acropyga are obligate coccidophiles, and A. epedana (the only species in Arizona) is  no exception.

the doesnt look like acropyga to me, they have long and thin gasters. I'm putting my bet on brachymyrmex depilis. They are very small, around the same size as solenopsis molesta maybe smaller. They
Are also smaller than other brachymyrmex from what I've seen.
Colony wish list:

Lasius latipes
Temnothorax pilagens
Temnothorax Americanus
Myrmica semiparasitica
Any formica microgyna group sp.
