I found this at the bottom of my ant supply bin. I can't remember where I got this from though...

Several people in the FB group have reported Tetramorium starting to fly near salt lake en masse. Formica fusca group have been flying for the last few weeks. Also found a termite alate but nothing much else down here given we have gone for several weeks without a day over 80.

[UtahAnts]

Sparse Tetramorium and parasitic Lasius flights throughout the valley for the last week or two. Temperatures are finally starting to rise over 80 on a daily basis. I've been keeping my eyes out for Formica queens but none seen yet.

[UtahAnts]

A large Tetramorium flight yesterday morning in the Provo to Spanish Fork area that lasted for the whole day. Saw a couple Formica alates throughout the week as well - all of this in suburban areas. Highs were consistently over 80 degrees the last week with breezy days and little cloud cover.

Cool!

Went through Canyonlands NP the last few days and camped outside of it on BLM land. Throughout the general desert region I saw the following species and genera: 

 

Either Pogonomyrmex occidentalis or salinus

Pogonomyrmex rugosus

Pogonomyrmex californicus

3 Pheidole species

Dorymyrmex bicolor

Dorymyrmex sp. (this species was having nuptial flights each night)

Myrmecocystus mexicanus

Myrmecocystus mendax

2 Formica sp.

Brachymyrmex sp.

Nylanderia hystrix

Camponotus vicinus

Crematogaster sp. queen (see images)

 

 

Any help on the queen ID below, I believe it's Crematogaster but I've never seen this species. The queen was found after dark with wings. She tore three of them off soon after she was introduced to a container.

7/19/23 - It rained about 0.1 to 0.2 inches in Emery county the day before, afterwhich I drove down near Cleveland and looked from 3 to 10 Pm.

 

Weather - Unexpected sameday thunderstorm dumped another half inch while Pogonomyrmex flights were ongoing at around 5 Pm.

Humidity - around 50%.

Winds - 5 to 15 miles an hour

Cloud cover - yes

 

Species flying and when: 

 

Pogonomyrmex occidentalis 12 to 3 PM

Small Pogonomyrmex sp. 12 PM

Pheidole sp. 8 PM

Formica sp. 12 PM

Myrmecocystus mexicanus 8:30 PM

Dorymyrmex sp. 7:30 PM

 

Also saw Camponotus vicinus colonies in the area.

More Pogonomyrmex flights throughout the state, but still waiting for the major monsoon season to begin.

 

The two desert species of queens from previous posts now have developing brood. Interestingly, this includes what I thought was a parasitic formica species but it seems my ID was wrong as they are now laying eggs. Any ideas?

Yesterday, on August 4, the massive Pogonomyrmex occidentalis flight of the year took place along the northern half of the state after a large monsoon storm swept through the area.

 

Weather of August 4 in Utah county:

-40% humidity

-85 degrees

-Little cloud cover

-Rained between 0.35 to 2 inches throughout the state

 

Time of flights: around 11:30 AM to 2:30 PM

 

--------------------------------------------------

 

The day before (August 3rd) in Emery county I also found Pogonomyrmex rugosus and occidentalis queens in freshly dug founding chambers, as they likely flew earlier that day or the day before. Additionaly Pheidole, Dorymyrmex (bicolor and all dark species) and Solenopsis molesta flew that night. I believe Myrmecocystus mexicanus flew on the night of August first or second as well, however the surface evidence of founding chambers was washed away.

Weather of August 3rd in Emery county:

-45% humidity

-High 80s

-Part cloud cover, heavy rain in the afternoon

Rained 0.35 inches the day before and an additional 0.3 inches the the day I went.

 

I was there from around 5:30 to 9:00 PM - All the ants out there, excluding the Pogonomyrmex, fly in the evening as the sun goes down.

Found some parasitic Lasius (possibly L. brevicornis) along with nightly Aphaenogaster flights over the last few weeks in the Utah valley area. Crematogaster, some Pheidole, and Aphaenogaster will continue to be flying for the next week or two, while Lasius spp. and Solenopsis molesta will fly en masse in about 2 weeks, given we get some rainfall sometime soon.

[Mep2001]

Can anyone ID these 3 queens? All found in Northern Utah (Alta up in the little cottonwood canyon) this morning around 10-12. First two pics are of a very small queen ~.1 in, queen in pics 3/4 is bigger but smaller than queen in 5/6. Queen in pics 3/4 is maybe .2 or .25 of an inch and Queen in pics 5/6 is a bit bigger so maybe .33 of an inch or so. First queen is black, second is black with some dark red that doesn’t show up great in pictures and last queen is more of a gold/brown. Plan to try and figure it out myself using antweb.org but wanted to know everyone’s thoughts. Thanks!

I'm really not sure about that first queen, better pics would help immensely. It also might be a drone or even a wasp.

 

The second and third queens are some sort of Lasius, probably not parasitic but take that with a grain of salt as I always have trouble starting them for some reason. 

 

After that rainstorm we had a few days ago I've also seen some Lasius flights around the valley, including parasitic sp, neoniger, and americanus. Along with Solenopsis molesta nuptial flights seemingly every night for the last few days.
