I also really want to find this species (not on my top tier list to find though and would want to find accidentally) but I have spotted a major in my local forest running around so you can expect to find them in forests. Like any typical Camponotus nuptial flight; you would want to find queens and alates starting from 4:00 PM to time like even 10:00 PM (I usually look around 5:00 PM to 6:00 PM when I catch Camponotus in particular. I’d say black light in May she their peak nuptial flights occur, or you could look now. Good luck!
Keeping:
3x - S. molesta
1x - C. chromaiodes
2x - F. pallidefulva
2x - C. cerasi
1x - B. depilis
2x P. imparis (colonies) 3x P. imparis queens (1x queen in test tube, 3x queens in test tube, and 6x queens in another test tube. Can't wait to see the results!)
