raspberry sawfly
LowTechnical, Gardening
Definition
Meaning
A common insect pest whose larvae feed on the leaves of raspberry plants.
Any of several species of sawfly (especially in the genera Arge and Priophorus) whose larvae are defoliators of raspberries, blackberries, and related cane fruits. The name can also be used more broadly by gardeners for similar-looking pests on berry crops.
Linguistics
Semantic Notes
The term is a compound noun. It is primarily used in agricultural, horticultural, and gardening contexts. The 'sawfly' part refers to the insect's order (Hymenoptera, suborder Symphyta), not a true fly (Diptera).

Differences
No significant lexical differences. Spelling remains identical. The pest is known in both regions.
Connotations
Purely denotative; signifies a specific garden pest. No regional connotations.
Frequency
Slightly more frequent in UK usage due to a strong tradition of domestic fruit gardening. In the US, the term is common in Pacific Northwest and other berry-growing regions.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct calque like 'малиновая пила-муха'. The correct translation is 'малинный пилильщик'. 'Sawfly' is one word, not 'saw fly'.
- Do not confuse with 'raspberry beetle' (another pest) which is 'малинный жук'.
Common Mistakes
- Misspelling as 'rasberry sawfly' or 'raspberry saw fly'.
- Confusing it with the 'raspberry beetle' (Byturus tomentosus) which affects the fruit, not just the leaves.

FAQ
Frequently Asked Questions
No, they pose no threat to humans. They are only a pest to plants.
They are small, greenish, caterpillar-like larvae, often with black spots, sometimes called 'slugworms' due to their slimy appearance.
Severe, repeated defoliation can weaken the plant significantly, reducing fruit yield and making it susceptible to other stresses, but it rarely kills established plants outright.
The best time is in late spring or early summer when the larvae are small and actively feeding on the leaves, before they cause extensive damage.
