I hadn't noticed a lot of them at any one time, but they have had a long season, much like most of the insects.
They could have been a mass hatching and they are newly emerged
We went to the beach Monday and there was swarms of them being washed up from the sea. Some were barely alive and others were dead.
Why would they be in the sea in those quantities?
Ive only seen one and that was today on my Sunflowers. Tried to take a pic but it didnt come out very clear. I think they are beautiful but yes I did know they could bite.
