a winged dragon with jaws too long to bite and too dramatic to ignore

means A large nocturnal insect with broad veined wings, the male sporting enormous curved mandibles that look fearsome but are too long to deliver a real bite, whose aquatic larva (the hellgrammite) is prized as fishing bait.

from The name's roots are genuinely murky. "Dobson" appears as an angler's term for the larva (the hellgrammite) in 19th-century American fishing usage, and the adult took its name from there — but who or what "Dobson" was is unrecorded. It may be a surname or a regional bait-fisher's word; honestly, no one is sure. The insect's order, Megaloptera, is on firmer ground: Greek megalo- "large" plus pteron "wing," a fitting tag for so dramatic a flyer.
