on my last encounter with a yellow jacket , within 10 min my blood pressure was 40 / 60, and i had no pulse at either wrist, nor either ankle, my vision was almost totally black .I was lucky to be near a emergency care center ,I parked my car in the middle of the road, fell in the door, and they saved my life.You are much braver than I my friend. I'll do close ups of honey bees but none in the hornet/wasp family. Too aggressive for me.
Great photos
Incredible shots! For attracting flies I put some fish (dead, of course) in a bucket of water and that gets tons of flies and also prevents the ants from eating it.
