Crane Flies Are Invading Ohio This Fall And They Look Like Giant Mosquitoes

If you think you’ve spotted a mosquito or two this fall, you’ve likely just encountered some crane flies. Due to last year’s fairly mild and wet winter, Ohio is seeing an abundance of both native and non-native crane flies this fall. Although these unique insects can appear unsightly—especially in the fall after the mosquitos are supposed to be long gone—there’s little to worry about.

Resembling giant mosquitos, crane flies are flying insects that are harmless to humans. This fall, Ohio is experiencing an abundance of these unique creatures that are commonly mistaken for mosquitos.

The fairly mild winter of 2019 and 2020 enabled the larvae to survive after hibernating underground to avoid the summer heat.
After hatching, the larva feeds on decaying plant matter underground and emerges in the fall as a crane fly.

As an adult crane fly, the average lifespan it just 3 - 5 days.
The Marsh Crane Fly is non-native to Ohio but can make an appearance in northern Ohio and Lake Erie counties.

These crane flies can also emerge in the spring as well as the fall.
Non-native crane flies can cause notable damage to grassy areas or other green plant material. Because they feed off of grass and greenery, turf can thin and leave room for weeds to sprout.

Luckily, most of Ohio doesn't experience this kind of damage because non-native crane flies are up north.
So, should you spot some of these creepy crawlies in your yard this fall hiding among the changing leaves (and you don't live close to Lake Erie), don't fret. They'll be gone in a matter of days!

If you want to discourage their presence, just rake your leaves often.
