Hover Flies

Hover Fly

Many people have been asking me about sweat bees. Here in Illinois we have had an invasion of hover flies.  They are about 1/4” long and will hover and land on you.  They are not bees. The easiest identifier is that they only have one wing on each side and bees have two wings per side. They cannot sting or bite although while they are licking you, you can feel it and you might think you are about to be stung, but they are after your sweat.  They are actually syrphid flies which is a term that includes a lot of flies. If you are like me, you’ve allowed your yard to grow taller because you don’t want to cut the clover. You’ve helped out your bees and hoverflies. They both feed on the same thing, pollen and nectar. I took this picture as one landed on my finger. Probably our wet spring provided a good breeding season. These flies are pollinators too and their larvae feed on dead organic matter. The larvae are predators of aphids. You’ll see less of them as we enter the gap between summer and fall nectar flows. You will not see any after the first frost. I’ve seen birds and dragonflies catching them. No, they will not bother your bees. It is useless to attempt to reduce their numbers. Bug spray usually doesn’t keep them off. Just enjoy them for a few more months.
