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?

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.
