Estoy de vuelta

Was Argentina fabulous?  Yes.  Am I exhausted after a sleepless overnight flight?  Also. I’ll try to think of some things to write about the trip once I’m lucid.  In the meantime I’d like to thank guest bloggers Scott and Eli for elevating the literary standards of the myrmecos blog during my absence. photo details: Canon [...]

Cephalotes pusillus is ever-present in cerrado. In fact, I have never encountered another ant that is so abundant in a natural system, tropical or temperate. They are generalist nesters and can be found in almost every piece of standing dead-wood and many live trees.
