Morphology

woolly + adelgid

This is a straightforward adjectival noun combination: 'woolly' (having a wool-like, fluffy appearance) modifies 'adelgid' (an insect), so the phrase denotes an adelgid with a woolly appearance. The meaning is compositionally predictable from the constituents and follows a common descriptive pattern, so a learner who knows both words would understand it.

Etymology

Woolly adelgid gets its name from the white, wool-like clumps that cover the insect and its eggs: woolly points to those fluffy, cottony masses and adelgid is the small insect that sucks sap from hemlock trees. So, when you see white cotton on hemlock branches, those 'woolly adelgids' are likely feeding and can damage the trees.
