OHIO – All over Ohio people are posting on the internet, where did these giant bugs come from? They look like a giant mosquito, or a daddy long legs fly, but they are actually called a crane fly and no they do not bite, because they don’t even have mouthparts.
Some crane flies never even eat, their entire job in life is to hatch, find a mate spawn, and die. The lifespan of the males is just 3 to 5 days.
What you are seeing on your garage doors and homes is exactly that, Late September early October is the mid-spawning season of this fly. With the last few years of mild winters, scientist say that a lot of the larve have survived the winters
The Larve of crane fly is called leatherjackets because of the tough exoskeleton, they mostly live in high organic material areas, and the Ohio species do not harm plants or grasses.
They will be gone before long just like the leaves.
