Wow this is like fort Knox! Anyway I was searching small bees that kill caterpillars, frogs and praying mantas when I came on this site. I am 67 years old ---- spend lots of time in the great outdoors all my life and came across a small swarm of small bees (maybe small yellow jackets) bees --- they look like sweat bees (about the same size ---small) and they were stinging and attacking a large black caterpillar. They kept at it for 2 days, until it was gone. I watched every chance I could. Never saw anything like it. Then two days later they are swarming a small green frog. Today I was in my yard talking to a neighbor, when I noticed a medium sized praying mantas ----- I pointed it out to him and we noticed the same small bees attacking it and stinging it ----it's eyes ---- under its wings ----the mantas tried to grab at them but they were persistent -----I moved the mantas, shaking off the bees . He is also an outdoor person and had never seen or heard of bees attacking a mantas. they are small BEES or small yellow jackets ----look like sweat bees!!!!! Just thought you would like to know Always something NEW to learn!!!!!!!
