1. Location of collection: Philadelphia, PA.
2. Date of collection: May 17, 2017
3. Habitat of collection: Urban environment; several queens collected from side of building & pavement below.
4. Length (from head to gaster): approx 4.5 mm
5. Color, hue, pattern and texture: Dark brown with small hints of yellowish hues on underside, resembles smaller Prenolepis imparis queen.
6. Distinguishing characteristics: Post-petiole absent
7. Distinguishing behavior: NA
8. Nest description: Seemed to come from holes in asphalt outside of where the flight occurred.

 

Notes: This is definitley a Nylanderia queen; it was caught in a flight where Nylanderia males and workers were overly present. I have a feeling it's either N. flavipes or N. terricola but I'd like to determine the species. A total of nine queens were caught during this flight; this one didn't make it so we decided to do a little photoshoot with her. I've kept the specimen, so let me know if it'd be helpful to get shots from different angles or different parts of her body.

 

Detailed images of the potential Colobopsis mississippiensis worker coming later.

Just saying but just because one species is dominant in one area does not mean that it can't be a different species. But I do agree with it being Nylanderia

If there are standing hairs on the antennal scapes, then it is N. flavipes.

If you've enjoyed using my expertise and identifications, please do not create undue ecological risk by releasing your ants. The environment which we keep our pet insects is alien and oftentimes unsanitary, so ensure that wild populations stay safe by giving your ants the best care you can manage for the rest of their lives, as we must do with any other pet.

 

Exotic ants are for those who think that vibrant diversity is something you need to pay money to see. It is illegal to transport live ants across state lines.
