dobsonfly

Believe it or not, young dobsonflies are called hellgrammites.

Multiple mating and lifetime reproductive output in female dobsonflies that receive nuptial gifts.

Dobsonflies spend most of their 2- to 5-year lives as freshwater larvae called hellgrammites.

Megalopterans are among the most primitive of winged insects in the world (Aspock et al., 2001) and include two families: Corydalidae (dobsonflies and fishflies) and Sialidae (alderflies).

Although maximum running and flying speeds in insects scale positively with body size (Dudley 2000, 2002; Bonner 2006), flying insects usually escape flying predators not by speed, but by maneuverability (Cloudsley-Thompson 1980) and acceleration, both of which are inversely proportional to body size (Dudley 2000, 2002) (e.g., syrphid flies vs large beetles, dobsonflies, mantids, etc.: McLachlan et al.
