Have you ever thought about how nutritious your bodily fluids are? Full of goodies like salts and proteins…Wild bees know all about it, feeding human sweat and tears as a source of nutrition.
Urban sweat bees, for example, use humans like a salt lick. “These bees prefer sweaty people—over most animals—because the human diet usually is so salty that their perspiration is saturated with the essential nutrient,” according to a recent feature in the Wall Street Journal on sweat bees. A new species (Lasioglossum gotham) of these bees was recently identified from a specimen netted in the heart of Brooklyn. Although they are as a group fairly common, they’re tiny and they don’t sting, which is why you probably haven’t heard New Yorkers complaining about them. “[M]ost people never notice when the tiny bees alight on a bare arm or leg,” says the WSJ.
