We've been driving around the Yucatan the past week. I've been trying to see their stingless bees. So far we've been stopping at every bee supply store and small town mercados to ask around. I've heard the same story repeatedly- "There used to be some around here, but every year fewer and fewer."
Anyway, I did manage to hook up with a guy that keeps Apis Trigona bees. Here's a couple of pics:
Taking the pictures, I was blocking their entrance for a while and ended up with a half dozen in my shirt and hair- and a couple up my shorts. I experienced a moment of panic, but they truely are stingless, but they do bite a little.
