I've seen a lot of info online about #SquashVineBorer being active only in June, or till mid-July or something like that.
I've been recording adult & egg sightings this year (Zone 6b, Southern Ontario). My first sighting was June 6th, and I've been seeing them ever since. Killed one laying eggs on my cucumbers this morning.
Once I stop seeing them regularly I'll drop another post.
