A dobsonfly is a large insect with distinctive long mandibles, prominent wings, and a generally ferocious appearance. The males have longer mandibles than the females, which they use for combat and courtship displays. Despite their intimidating appearance, dobsonflies are not aggressive towards humans and are primarily attracted to bodies of water, where their larvae develop. They are commonly found near streams and rivers, and their presence serves as an indicator of good water quality.
