It's a type of hornet we have up at the big redwoods here,they have hives like yours up in the trees,that is a hive in the pic isn't it? Ours are little yellow boogers and the eat meat,especially when ya go to bar-b-quein or makin a sandwich,they will land on ya and take a hunk out of your arm and it hurts like the dickins!! When we camp we hang hot dogs on a string above a bowl of soapy water,they will eat till they can't fly and fall in the water and the soap keeps them put.
Last time i went bear huntin(campin) when we got ready to leave there was a hive up in a tree above us,right before we left i put a target arrow right through one,then we jumped in the trucks and made tracks================>
Dang meat bees drove us nuts! I saw where one guy made a cage from screen material and captured some hornets,took different colored poster paper and tore it up and threw it in the cage with the hornets and they made a nest out of the different colors.
