Wonderful Wacky Water Critters
The blackfly larva moves like an inchworm, first spinning small loops of silk with its mouth, then attaching itself to the loops with tiny hooks on its back end. It is the original Velcro!® It also uses the silk as a safety line to reel itself back if knocked off its rock. It eats whatever the river brings to it, mostly bits of dead plants. (Talk about a life of ease!) The adult blackfly has a short body with a humped back. This critter can be a real pest in the summer. Its bite is not very painful . . . until later. Some blackflies can only live in clean streams; other kinds are very tolerant of pollution. The female lays eggs on rocks in streams and rivers. The blackfly is food for other animals.
