I was sitting on my deck, enjoying a cool drink on a summer afternoon, when a bee kept buzzing around me and trying to get into my drink. Then, on closer examination, I realized this wasn’t a bee; it was a fly! How can you tell the difference between bees and flies?
Certain flies, especially hoverflies or drone flies, imitate bees. The various species can resemble a bee’s shape, have black-and-yellow stripes and hairy bodies, buzz around like bees, and feed on nectar from flowers. But they are not bees. You could call them fake bees, hoping to fool potential predators–and me. These bee imitators can fool you unless you look closely and know the difference between bees and flies.
One major difference is that flies have only one pair of wings, while bees have two pairs, even though their transparency may make it hard to see both pairs. Another difference is the eyes. The eyes of flies are large and cover most of their heads, but bee eyes are much smaller. Flies also have short, stubby antennae, while bees have long, slender ones. One crucial difference, as far as I’m concerned, is that bees have stingers, but flies don’t.
When one creature imitates another, it’s called Batesian mimicry. It happens among many species. A viceroy butterfly looks similar to a monarch butterfly unless you look closely. What’s the point of Batesian mimicry? Monarch butterflies have a toxic, bitter taste that deters potential predators, while viceroys do not. The monarchs get their unpleasant taste from the milkweeds their larvae feed on. One bite will scare away potential predators. Viceroys benefit by avoiding predators, even though they might make a delicious meal for a bird.
Getting back to the difference between bees and flies, bees are generally avoided because of their potential to sting. By looking like a bee, flies gain protection from their enemies. That shows great cleverness on the part of those hoverflies or drone flies, as well as the viceroy butterflies. Or does it? Actually, I’m sure those flies didn’t choose to look like bees. The cleverness goes back to the Creator who gave the insects that special protection. God provides for his creatures, including us. For that, we can be thankful.
