camponotus pennsylvanicus nuptial flight time?

[JustSomeKid]

So for the past year I've REALLY wanted a large camponotus species like pennsylvanicus and I was wondering what time of day is better to find them, I know an area where there are plenty but I haven't found a queen yet. I normally go about 2-3 pm.

In my area, they often fly late afternoon and all evening.
