This cute lil' guy is a hover fly. They drink nectar, sugarwater from hummingbird feeders occasionally, and sweat. This one didn't seem to enjoy the clover flowers, so he drank my sweat instead! As a larvae, he would have been eating aphids, and other pesky buggers. But after he changes to an adult hover fly, he goes more to liquids, like sweat, nectar, dew, and thankfully for me, a hoverfly lover, NOT blood. I would have been in bad luck if they did, though. :V
Keep hovering, peeps!
