Okay so I am probably too late for the T. caespitum flights in my area now. I live in Northern VA. I saw a queen on Sunday in the mall but someone stepped on her before I could even try and get her. Anyway, after that I have been waiting ever since for more flights, and it's been raining here lately followed by a sunny day and then more rain. Does T. caespitum fly during the daytime or at night? I have actually never experienced a T. caespitum flight.
