Behavior, Diet & Habits
Adults typically do not feed. They are attracted to lights and may been seen resting on walls near outdoor light fixtures. Larvae are aquatic and predators of other aquatic organisms. Fisherman sometimes use them as bait for fish.
Habitat & Reproduction
Females lay eggs in fast-moving streams and rivers. Dobsonfly larvae emerge and often hide under rocks and in crevices. They go through a series of molts until they pupate into adults. The larvae become adults after an underwater stage known as hellgrammites.
Larvae Bites: Signs and Symptoms
Typically living under rocks in flowing rivers and streams, hellgrammite larvae feed on small, soft-bodied insects. Their heads are equipped with sharp pincers capable of delivering painful bites to humans. While hellgrammites are not aggressive, bites from these larvae often pierce the skin and cause very minor bleeding.
