Richmond VA 4/22/2022, year old Camponotus Queen. What species?


Best Answer Mettcollsuss , April 22 2022 - 1:01 PM

Just going off the queen, I don't think there are any pennsylvanicus with legs that light and the anterior edge of the gaster has a very faint red color, which should mean chromaiodes. Shouldn't be anything else that matches that.

1. Richmond Va, walking park in a log.

2. Last may I believe, Hard to recall exactly.
3. Suburban Richmonda Virginia walking trail around a pond. Some trees and brush but mostly office buildings. 
4. I think the queen is 3/4 inch but its hard to tell when measured exactly the length. Maybe a little more or less.
5. I thought she was all black and a lock for C. pennsylvanicus. However recently I got  a magnifing glass and noticed the legs are actually red. I can't tell about the under-area of the mesosoma.
6. See pictures
7. N/a).
8. Rotted log, under bark.

9. Unsure
 

I thought Camponotus Pennsylvanicus, and then I thought maybe Camponotus Herculeaus. But they aren't thaaat red. So maybe some kind of mix? There were a couple other regional species I considered due to coloration but thought head shape may be off.

 

Please let me know what you think!

Dark morph Camponotus chromaiodes, I believe.

Think so? I was expeting them to be more red in person, though I'm not familiar with the dark morph part of what you mention. 

 

Edit: Okay yeah I was just reading up on their article in antwiki and I see what they are talking about in the "Comparisons" section. Could be a good canidate.

Occasionally chromaiodes can be so dark as to have completely dark workers like this. Is there any red on the queen's gaster directly behind the petiole? I have yet to see a chromaiodes queen dark enough to not have at least a small patch of red there.

I looked very hard with the human eye to avoid picture color distortion and I cannot see any red on the gaster. I had the thought that it could be on the underside however
