Low / SpecializedInformal / Technical (Entomology)
Definition
Meaning
A small insect, particularly the nymph of a froghopper, which secretes a frothy, protective mass resembling saliva on plant stems while feeding.
Informally, can refer to any insect that creates a frothy secretion; metaphorically, something small and insignificant that creates an unsightly, messy, or annoying residue.
Linguistics
Semantic Notes
The term is descriptive of the insect's most notable behavior rather than its taxonomy. In casual use, may be confused with 'aphid' or other sap-feeding insects.
