Morphology

dobson + fly

The compound is transparently compositional: 'dobson' denotes a particular large insect (or its larva) and 'fly' denotes an insect, so 'dobson fly' is readily interpreted as a type of fly. This noun–noun naming pattern for species is common and predictable, so a B1 learner who knows both constituents can infer the meaning.

Etymology

Dobson fly may be named after a person called Dobson who first collected or described the insect. The name fits the image of a large fly with long, curved jaws and water-living larvae used as fishing bait, so today dobson fly means that big night-flying insect.
