Flying insects everywhere - how do you quickly ID an insect as an ANT?  Are they easily identified by their elbowed antennae?  Is this definitive? Is this an ant?  Any IDs?  Thank you.

 

 

Egg-like; however, under magnification, these don't look like eggs....

 

 

Added full wing shot...

Brachymyrmex patagonicus is not present in Arizona... At least according to AntMaps.

antwiki disagrees -- Which one is more trusted or up-to-date -- antwiki or antmaps?   Thanks.

I think I see the issue... B. patagonicus is an invasive species

Antmaps doesnt show invasive species on diversity view. B. patagonicus and B. obscurior are both in Arizona.

[Aaron567]

Definitely either B. patagonicus or obscurior.
