Note to Paul - did you see any larva? Caterpillars? larval ladybugs, larval lacewings? Although those adult insects were feeding from the flowers, if they ingested pesticides from that flower's nectar site wouldn't you expect said pesticide to kill them shortly afterward? I suppose the only way to know would be to net/catch some and hold them for 24 hours so see if they exhibited normal behavior. Unfortunately we can only speculate on what chemical mix was being applied. It may be just a fungicide as you stated.
I believe that my massive monarch caterpillar kill last month was due to my husband's herbicide-spraying next to our home. In 40 years, I've never lost 98% of my cats in 24 hours like this. Ever. He was NOT using a pesticide, but an herbicide for dandelions, etc. He was sorry about the results and I just don't understand his drive for a 'perfect' lawn - it's not important to me as living butterflies are. And bees. And earthworms, etc...
