Morphology

proleg = leg (semi-transparent) = pro + leg

Formed from the recognizable parts 'pro-' + 'leg' so learners can tell it's a kind of leg-like appendage, but the technical sense (not a true thoracic leg and the precise meaning of 'pro-') is specialized.

Etymology

Proleg comes from the parts pro- ('before') and leg, so it literally means an extra or 'front' leg. These small, stubby legs on insect larvae help them grip surfaces, which is why we call them prolegs.
