The Camponotus flight in parts of BC Canada I have found this year have been delayed due to the extremely dry weather making it dark for queens to dig after flight. At two good locations here In Victoria I have only found signs of a few small flights. I expect larger flights this week after some significant rain this coming weekend.
Good to know. The one I got in early May was infertile. I'll be looking out for flights soon. Doesn't look like it is going to warm up and be sunny till Mon or Tues though.
