lac insect
C2Technical/Specialised
Definition
Meaning
A tiny scale insect (Laccifer lacca, Kerria lacca) that secretes a hard resinous substance called lac, used historically to make shellac.
The insect itself and, by extension, the source of the natural resin lac/shellac, cultivated for use in varnishes, dyes, and formerly for record production.
Linguistics
Semantic Notes
A compound noun, most often used as a singular count noun ('a lac insect'), but can be used generically ('the lac insect'). Refers specifically to the producer, not the product (which is 'lac' or 'shellac').
Dialectal Variation
British vs American Usage
Differences
No significant lexical difference. 'Shellac' is the more common term for the product in both dialects.
Connotations
Technical/industrial or historical/artisanal, with no dialectal variation in connotation.
Frequency
Equally rare and specialised in both dialects, appearing mainly in entomological, historical, or art conservation texts.

Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводить как "насекомое-лак" в значении "лак для ногтей/пола". Речь идёт о конкретном виде щитовки.
- Не путать с "лаковым жуком" — это устоявшийся термин 'лаковый червец' или 'лаковая щитовка'.
Common Mistakes
- Using 'lac insect' to refer to the resin itself (that's 'lac' or 'shellac').
- Pluralising as 'lacs insects' instead of 'lac insects'.
- Capitalising as a proper name: 'Lac Insect' (not standard).

FAQ
Frequently Asked Questions
No. Both produce red dyes, but they are different species. Cochineal insects (Dactylopius coccus) feed on cacti and produce carmine. Lac insects feed on tree sap and produce lac resin, which can yield a red dye and shellac.
No. 'Lac insect' is the living producer. 'Shellac' (or 'lac') is the refined resinous secretion harvested from the insect and its host twigs.
It is a highly specialised term, common only in technical fields like entomology, agricultural history, and art conservation. The product name 'shellac' is far more widely recognised.
Traditionally and primarily in India and Thailand, on host trees such as ber, kusum, and ghont.
