Morphology

plant + louse

The compound follows a straightforward noun + noun composition: 'plant' specifies the host/location and 'louse' names a small parasitic insect, so a B1 learner who knows both words can infer 'a louse that lives on or feeds on plants'. The pattern is cross-linguistically common (equivalent compounds or terms exist in many languages), making the meaning directly derivable and transparent.

Etymology

Plant louse comes from the image of a tiny insect that sits on a leaf and sucks the plant's juice like a louse on a person. So, it means 'a small insect that feeds by sucking the juices from plants'.
