It got up to the mid-80's yesterday where I live. I would have gone queen hunting but from my experience the only Camponotus to fly this early are species in the subgenus Myrmentoma, as well as Camponotus chromaiodes. I have very bad luck with Myrmentoma Camponotus, so I figured I'd let them be this year. It's strange, but I think Prenolepis may have flown for the first time in my area yesterday as well. It's weird to have Camponotus and Prenolepis fly for the first time on the same day, because yesterday not only was hot, but it was also only the second day of the year so far to reach over 75 degrees.
Anyways, I'm interested to hear if others have seen Prenolepis yet.
