jumping plant louse
Low (specialist/technical)Technical/Entomological
Definition
Meaning
A small, sap-sucking insect of the superfamily Psylloidea, known for its ability to jump when disturbed.
Refers to any member of the family Psyllidae, which are plant pests that can cause gall formation and transmit plant diseases. In casual usage, may refer to any small jumping insect found on plants.
Linguistics
Semantic Notes
The term is specific to entomology and agriculture. It is not a true louse (order Phthiraptera) but belongs to the order Hemiptera (true bugs). The 'jumping' descriptor distinguishes them from other, more sedentary psyllids.
Dialectal Variation

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'вошь' (louse) alone, as this refers specifically to human/animal parasites. The correct biological term is 'листоблошка' (listobloshka).
Common Mistakes
- Using 'grasshopper' or 'flea' incorrectly. Confusing it with aphids (which don't jump). Treating it as a plural noun ('louses') instead of the irregular plural 'lice'.
