Morphology

Fenusa + pusilla

This is a Latin binomial (a scientific species name) referring to a specific small sawfly; its meaning (a particular insect that mines birch leaves) is specialized and not constructed following ordinary English compositional patterns. The elements are proper names/Latin roots (and one element is dictionary-missing), so a B1 learner who knows the constituent words would not be able to derive the species' biological meaning from them.

Etymology

Fenusa pusilla comes from Latin. The second word pusilla means 'very small', so the name literally points to a tiny insect. That image helps you remember: these small black sawflies have young insects that make thin tunnels inside birch leaves and can eat many leaves, so the name fits their size and the damage they cause.
