Our biologists found this dobsonfly larva (just before its adult stage) in Little Barton Creek during biological sampling for the Environmental Integrity Index (EII). Watch its gills pulse as it gathers oxygen from the water. Dobsonflies are sensitive to environmental conditions so their presence is an indicator of good water quality.

Explaining Insects 🦋 on Instagram: "The dobsonfly is a large, fierce-looking insect known for its intimidating jaws and dramatic appearance. Despite its scary look, it’s mostly harmless to humans. The males have extremely long, curved mandibles that can look like antlers, while females have shorter but stronger jaws capable of giving a small pinch. They are usually found near freshwater rivers, streams, and lakes because their larvae—called hellgrammites—live underwater and are fierce predators

Haw River Assembly on Instagram: "Happy Macro Monday! This week we're featuring the hellgrammite, the larval stage of the dobsonfly. These creatures are excellent indicators of water quality because they can only survive in clean, well-oxygenated streams. Our Haw River Watch volunteers identify macroinvertebrates like hellgrammites during four seasonal snapshot surveys each year, helping us determine stream health and notify state agencies when water quality is threatened.

Solvia Origin on Instagram: "‼️The Dobsonfly: An Ancient River Predator Disguised as an Insect‼️ - The dobsonfly (family Corydalidae) is one of the largest and most misunderstood insects on Earth, not because of what it does as an adult, but because of the life it lives before anyone ever sees it.
