Dobsonfly

Large insects with intimidating mandibles in males that are actually too large to bite effectively. Aquatic hellgrammite larvae are prized as fishing bait and indicate clean water.

💡

Male dobsonflies have terrifying mandibles up to 40 mm long, but they are so large the males cannot actually generate enough force to pinch — the females bite harder.

A bizarre nemopterid with extremely long, thread-like hindwings. Males have hindwings that can be several times their body length.

💡

Did You Know?
