Looks like Lasius interjectus to me.

1. Location (on a map) of collection: Central NJ, US

2. Date of collection: June 29 2020
3. Habitat of collection: Mulch trail in wooded area. Came across what I'm guessing was their nuptial flight!
4. Length (from head to gaster): 8 mm. Male alates were much smaller, perhaps 1/4th of the size of the females?
5. Color, hue, pattern and texture: Red all over (including gaster). The male alates were a much darker color, like dark brown or black.
6. Distinguishing characteristics: Lighter bands on gaster
7. Distinguishing behavior: N/A
8. Nest description: I found large clusters of alates at the entrances of fairly sizable holes (a bit smaller than a tennis ball at the entrance) in the mulch, which I think were their nests?

9. Nuptial flight time and date: 8:00PM, June 29 2020, about an hour before sunset.

 

I'm totally new to this, so any help would be appreciated. I was walking on a mulch trail in a wooded area in Central NJ and came across what I think was a nuptial flight taking place. I'd estimate there were as many as 50 queens! I gave them some privacy and came back about a half hour later, and managed to capture about 8 queens that were wandering around in the periphery after the nuptial flight. I'm guessing these are either solenopsis molesta or pheidole bicarinata?

I agree.


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).

Thanks for the quick replies! That's tough, it sounds like I'd have to find a host colony for a given queen to thrive. Given that I have multiple queens, I'm wondering whether I'd be able to pair them up in a host / parasite set up. Time to read up on this species...

I second this.
