I ended up finding two other queens running around that shouldn't be out this time of year as far as I know. One is a formica fusca group that I'm familiar with, I caught a few last summer, but in July.
The other one is a mystery to me. It's about the same length as the fusca but skinnier. The most numerous queens I find in the yard are formica pallidefulva group but this looks very different.
These were spotted on a sidewalk in a suburban area by the way. Interestingly I did also nab a pallidefulva sp queen about this time last year running across the driveway.
Here's the fusca sp:
Here's the unknown:
Here they are side by side with a cm ruler:
Any ideas? Thanks!
