Morphology

spring + cankerworm

The noun is a straightforward composition of 'spring' (the season) modifying 'cankerworm' (a caterpillar that harms trees), so the combined meaning — a cankerworm associated with or active in spring — is directly inferable from the parts. Season + animal/pest compounds are a common, productive pattern in English and other languages, so a B1 learner who knows both constituents would readily understand this term.

Etymology

The noun spring cankerworm comes from two simple parts: spring, because this caterpillar appears in early spring, and cankerworm, an old name for caterpillars that eat leaves and cause 'cankers', or sore spots, on trees. That's why the name means 'a caterpillar pest that eats and damages trees in spring'.
