Morphology
Hessian + fly
The compound clearly marks a type of fly (fly = insect), so a learner who knows both words would infer it denotes a particular kind of fly; however the specific sense — that its larvae infest and damage wheat — cannot be predicted from 'Hessian' (a proper/adjectival element unlikely to be meaningful to a B1 learner) and is historically/entomologically specific. Because the headword yields the general category but not the important pest meaning, the expression is only partially transparent.
Etymology
Hessian fly gets its name from a popular 1700s story: people thought tiny flies were brought to North America in the straw used by Hessian soldiers and then damaged local 'wheat' crops. So the name helps you remember that this small fly attacks and harms 'wheat'.
