Doug, this should narrow it down.
mid may until about the end of June..... black flys
end of June until the end of July........... mosquitoes
for the first 2 weeks of August......... no see 'ums( local terminology), can't see them and they bite like hell
3rd week of August, the first frost. I've had to light the fire at night during the last week of August... it's depressiing.
All of the bugs mentioned above bite. The closer you are(like right next to it) to the coast, the safer you are. Something to keep in mind while camping.
