Have been under air quality alerts off and on for a couple weeks, back up to hazardous the last few days with the smoke from the wildfires in Canada blowing down this way. Wondering if the poor air quality and smoke affects pollinators? Noticed what I'd peg as the "usual amount" buzzing around a few weeks ago, now virtually none. Have been seeing maybe 2-3 bumblees a day. A DAY! Haven't really noticed much of other flying insects, either. I have lots of goodies planted for them. Can't figure out any other reason for the decline, but I don't know enough about it to say the air quality is causing them not to fly or affecting them in some other way (hopefully not killing them off).
