There are hundreds of species of crane flies in North America. Their larvae (pictured here) range in color from tan to gray to green and resemble a caterpillar. While you may not have seen the larvae before, you’ve likely noticed the adults. They kind of look like a mosquito on steroids …but luckily have no interest in you or your blood. Adult crane flies only live about 10 to 15 days. Their primary purpose is to mate. The females will lay eggs in suitable habitat …which depending on the species can range from water, soil, or a rotten log.
