cabbage moth
lowspecialist (horticulture, agriculture, gardening), technical (entomology), everyday (among gardeners)
Definition
Meaning
A common insect (Mamestra brassicae) whose larvae feed on and damage cabbage and other brassica plants.
In broader, sometimes regional usage, it may refer to other moth species whose caterpillars are pests of cabbages (e.g., Diamondback moth).
Linguistics
Semantic Notes
A compound noun where the head is 'moth' and 'cabbage' denotes its primary food source/habitat. It refers specifically to the adult moth, though the pest damage is caused by its larval stage (cabbage caterpillars).
Dialectal Variation
British vs American Usage
Differences
No significant lexical difference. 'Cabbage worm' is a more common non-technical term in the US for the caterpillar stage.
Connotations
Identical in both: a significant agricultural/horticultural pest.
Frequency
Slightly higher in UK due to greater prevalence of allotment and home vegetable gardening discourse.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'капустная моль'. While understood, the more common specific Russian terms are 'капустная совка' (for Mamestra brassicae) or 'капустная моль' often refers to the Diamondback moth (Plutella xylostella).
Common Mistakes
- Using 'cabbage moth' to refer to butterfly larvae (e.g., cabbage white butterfly). While both are pests, they are different insects. Confusing the adult moth with the damaging caterpillar stage in description.

FAQ
Frequently Asked Questions
No. They are different insect species. The 'cabbage white' is a butterfly (Pieris rapae), while 'cabbage moth' typically refers to a night-flying moth (Mamestra brassicae). Both have caterpillars that eat cabbages.
The adult Mamestra brassicae moth is nocturnal, with greyish-brown forewings featuring distinctive white, kidney-shaped markings and darker bands. It is less conspicuous than the white butterflies seen during the day.
Common methods include using fine insect netting to exclude the moths, inspecting leaves for eggs and larvae, using pheromone traps to monitor adults, and applying biological insecticides like Bacillus thuringiensis (Bt) that target caterpillars.
Yes. While cabbages and related brassicas (like broccoli, kale) are preferred hosts, the larvae can also feed on a range of other plants including lettuce, beet, and potato.
