Morphology

Lens + louse

The word 'louse' clearly signals a parasitic insect, and if a learner recognises 'Lens' as a taxonomic genus (capitalized), they can infer this denotes a species/type of louse — a parasitic organism. However, the meaning relies on domain-specific scientific naming conventions and the capitalised genus, which many B1 learners may not know and might instead interpret as a louse on a camera or optical lens, so the transparency is only partial.

Etymology

The noun lens louse probably comes from seeing tiny lice on the aquarium glass: lens refers to the glass and louse to a small clinging insect. These little creatures stick to fish or tank surfaces and are seen as a 'pest', so the name came to mean 'a small parasite in aquariums'.
