Acromyrmex species are less polymorphic than Atta species...i do not believe they have the very large "soldiers" like Atta does...Desert species still go out to forage at times simply because they may...

Excellent pictures of Acromyrmex versicolor, "Tetramorium". BTW, the spelling is "minim" (short for minimum), which is synonymous with nanitic.

Very nice key, thanks for the link. So A. versicolor is the only Acromyrmex in the US? Somehow I got the idea that A. octospinosus occurred in the US as well.

Yes the only Acromyrmex in the U.S is versicolor. I am not sure I buy the subspecific distinction used in the key in question either, the distinctions used are some that tend to be on the variable...

According to the ITIS, there are 26 species of Acromyrmex described at this time. No doubt most of the 48 subspecies will turn out to be synonyms at some point in the future.

I work in a fungus growing ant lab in Austin, TX. One of my coworkers recently brought back some Acro's from Panama that he believes to be coronatus. I have heard they build thatched roofs over their...

I never heard of thatched roofs before. Maybe someone else will give us the answer. Sounds interesting.

leafcutters have a tendency to create piles of forage material when the supply is much greater than demand in the nest....for example, the Atta cephalotes colony in the central park zoo in NYC creates...

I'm told the thatches are distinct from what Atta does, and that it is specific to Acromyrmex coronatus. You'd think with something that unique there would be pics online but I can't find anything.

The professor I work for (Ulrich Mueller) has seen them do this both in the wild (Panama) and in labs. He just got back from Brazil and suggested I try fresh leaves. I'll post a picture if I can get...
