2 species to identify

[PDelta41]

The first species is a tiny red or yellow species

She was caught July 7 in the early evening, in Dayton, NV, USA
She's about 5mm long (just under 1/4 inch).


The other species is suspected to be a Camponotus vicinus.


They were caught in mid-June, in Dayton, NV, USA
They are about 12mm long (1/2 inch)

Thanks!

The first is probably a solenopsis or pheidole species.

Hrmm. Any possibility that it's a brachymyrmex depilis? Does anyone know when they fly? They look like the right shape, size, color and nest preferences.

Brachymyrmex Only Have 1 Petiole Node Though; I'll Say That Solenopsis Sp Seems More Likely.

Looks like a Solenopsis thief ant and either Myrmecocystus or Formica. More/better-lit pictures might get you a little further.

Ok the first one looks like it could be Solenopsis xyloni, if not you only have like 3 species of Solenopsis in Nevada. The second could be Myrmecocystus.

Okay, after researching the genera you suggested, (and some really grainy videos with my phone), I agree that the tiny red one is Solenopsis molesta (though she was caught July 5). Agree that the big one is Formica sp., likely either Formica neogagates or Formica neoclara. Not that my track record with identification is anything but lousy (though I'm pretty sure I at least got my Tetramorium e and Pogonomyrmex californicus right).

I'll post a bunch more images (with the best lighting I could figure out) in the next post. This species moves in rapid bursts, with frequent brief pauses. They are also excellent climbers.
