These queens were collected and photographed in Colorado.

 

Queen 1, Pogonomyrmex sp.

 

1. Location (on a map) of collection: Confluence Park, Downtown Denver, Colorado
2. Date of collection: August 9, 2019
3. Habitat of collection: Dry-mesic prairie/desert
4. Length (from head to gaster): 9.5-10.5 mm
5. Color, hue, pattern and texture: Bright red-orange; large/wide head; thin, wasp-like gaster; prominent, sculpted petiole nodes; 12 antennal segments.
6. Distinguishing characteristics: All characteristics indicative of Pogonomyrmex.
7. Distinguishing behavior: 
8. Nest description: Founding chamber in sandy clay soil; was spotted while excavating chamber.

9. Nuptial flight time and date: Unknown, presumably within the past few days.

Queen 2: Formica sp.

 

1. Location (on a map) of collection: Fish Creek Falls, Steamboat Springs, Colorado.

2. Date of collection: August 6, 2019

Hopefully, someone from down south can identify the first queen. I suck with Pogonomyrmex, haha.

 

I'm going to argue that the second queen is actually Formica subpolita.

 

The third queen is a slave raider from the F. sanguinea group, maybe F. aserva. If one does not know the region of collection, It's quite difficult to narrow slave raiding Formica down to the species.

I believe you mean species. Also, the queen looks a bit like a claustral Pogonomyrmex, as she is quite bulky.

Hi there! I went on a 6 month or so hiatus, in part due, and in part cause of the death of my colonies. 

However, I went back to the Sierras, and restarted my collection, which is now as follows:

Aphaenogaster uinta, Camponotus vicinus, Camponotus modoc, Formica cf. aserva, Formica cf. micropthalma, Formica cf. manni, Formica subpolita, Formica cf. subaenescens, Lasius americanus, Manica invidia, Pogonomyrmex salinus, Pogonomyrmex sp. 1, Solenopsis validiuscula, & Solenopsis sp. 3 (new Sierra variant).

Sorry for the confusion, I meant that if the identifier does not personally know the region and it’s ant fauna, it can be quite difficult to identify them.

I see. Out of curiosity, why slave-making and not parasitic?

Because like a parasitic queen and going inside a small/established formica host colony, this queen will do that and then it keeps on having to raid other colonies and is fully dependent on host colonies all through out its life, raiding the colonies for brood. Feel free to correct me, I'm not sure if this is 100% accurate. I'm not sure about the first part and they might even just steal brood instead of full on parasitizing the colony.

Not all sanguinea group are obligate slave makers. I believe the only one confirmed to be is Formica subintegra (that I've seen). Formica aserva is known to be facultative though and I strongly believe this queen to be aserva.

That being said I'm not about to argue with the guy who wrote a huge breakdown of parasitic Formica lol.

I'll say Pogonomyrmex occidentalis based on the way the rear mandible bends backward.


Currently keeping:

 

Tetramorium immigrans, Pogonomyrmex occidentalis

Myrmica punctiventris, Formica subsericea

Formica pallidefulva, Aphaeogaster cf. rudis

Camponotus pennsylvanicus

Camponotus nearcticus

Crematogaster cerasi

Temnothorax ambiguus

Prenolepis imparis

Small update. The second Formica queen has a worker! She is small and black. She and her mommy are healthy and living in a THA mini hearth. Any ideas on how I could narrow down the ID?

To me it looks like Formica neorufibarbis.


Ants I have: Tapinoma sessile(2 queen colony). RED MORPH Camponotus neacticus(now has pupae!), Tetramorium immigrans (x3), Aphaenogaster sp, Temnothorax sp, Brachymyrmex sp.   possibly infertile   :(,  Ponera pennsylvanica, and Pheidole morrisi!  :yahoo: 

 

Other insects: Polistes sp. Queen

                    

Ants I need: Pheidole sp., Trachymyrmex sp., Crematogaster cerasi , Dorymyrmex sp. Most wanted: Pheidole morrisii

I definitely agree that the last queen is raptiformica. Founding them is the same as other parasites although most species can open pupae.
