I shouldn't be that close to these things; I'm very much allergic to them.
This was one HUGE bee. Perhaps the queen? It's either an overweight hornet or a slim bumblebee. (Bald Faced Hornet - Provided by Rob)
My lens was nearly touching the bugger. I was there for a while watching it build it's nest; It'd get material and come back and add to the hive.
I was so close to petting it lol. It's a good thing I didn't.
One of 7 bee hives in my backyard. The others were all wasp nests.
