Howdy Folks,

I went to take the dog for a walk and it's humid, overcast, and these things are flying everywhere. Their bodies are about 1 cm long. Can you folks help me ID them and tell me how to distinguish male from female?

Thanks

John

These all appear to be Tetramorium immigrans males. There are a few ways you can tell that they are male, but perhaps the most notable distinguishing feature is your specimens’ very small head-size relative to the rest of their bodies.
