I have a queen I found a few days ago (Feb 22) and have been trying to figure out what kind it is. I'm new to ants and need all the help I can get!
Thank you!
- Mal

1. Location (on a map) of collection:
Portland OR
2. Date of collection:
Feb 22nd 2022
3. Habitat of collection:
Kitchen, Suburb, Grassy/Meadow
It rained for three days straight, ending the night before collection
4. Length (from head to gaster):
5mm/.5cm
5. Color, hue, pattern and texture:
To the naked eye she appears fully black. Zoomed in she is dark brown-black on the abdomen with yellowish legs. Shiney, no apparent hairs. Slight banding - that might mean she's bred?
6. Distinguishing characteristics:
Yellowish legs
7. Distinguishing behavior:
I am sorry I am new to ants and this is the first queen I've seen. When I first caught her she appeared to try and spray me with acid. Since then she has been very friendly.
8. Nest description:
I have no idea where she came from. I found her on my kitchen table. It snowed here yesterday and I haven't seen any other ants out and about.
9. Nuptial flight time and date:
I didn't see any other ants except her.

They told me she is a Lasius, but I have struggled to narrow it down further.
Any help or advice is greatly appreciated!
Thank you!

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).

I’d ditch the plastic container and get her a proper test tube setup. She likely won’t be able to found in there.
