Dobsonfly larvae, commonly known as hellgrammites, are primarily preyed upon by various aquatic predators, including fish such as trout and bass. They are also vulnerable to larger insects, amphibians, and birds. The larvae's habitat in freshwater environments makes them a key food source for these predators, contributing to the aquatic food web. Their tough exoskeletons can provide some protection, but they remain an essential part of the diet for many species.
There are over 220 species of dobsonfly so you'll have to be more specific in telling us what you want to know.
4 inches long
No, we just caught one in my front yard. It is not extinct.
they form big groups and wene predters come they atack and ther is a fest right ther.
dobsonfly live near bodies of water for that most part, they spend most of their lives in the larval states as water creatures, when they grow up they live for only seven days or so and primarily live near the body of water from which they were born.
If it's the same thing we called a "helgermite" back when I lived in WV, it's actually called a Dobsonfly. They are a variety of insects native to the Americas, Asia and Africa.
Dobsonflies eat small bugs and some plants
A Dobsonfly is a large insect with long mandibles, prominent eyes, and clear wings. Males have long mandibles that resemble antlers, while females have shorter, stouter mandibles. They are usually brown or black in color and are known for their intimidating appearance.
There are many different types of larvae and they eat different things that include leaves from various plants like milkweed. Some larvae eat meat and others eat insects like aphids.

A helgramite is the larval form of the dobsonfly. They are aquatic insects found in streams and rivers, known for their large, aggressive appearance with powerful mandibles. Helgramites are commonly used as bait by fishermen due to their attractiveness to fish like bass and trout.
