Dogday harvestfly

The dogday harvestfly is black with green markings. Wings are clear green along their rear. Adult is not known to eat. The nymph feeds on root juices, especially pine and takes 3 years before maturing. A new generation hatches each summer in the same area. They are seen during the hot, dog days, of summer--that is where their name comes from. Their sound is a powerful call that sounds like a circular saw cutting through a board.
