- Avoid calquing as 'изумрудная моль' as 'моль' typically refers to clothes moths/pests. Use 'изумрудная бабочка-моль' or 'зелёная ночная бабочка' for clarity.
- Do not confuse with 'майский жук' (cockchafer) which is a beetle, not a moth.
Common Mistakes
- Misspelling as 'emerald mouth'.
- Using it as a general term for any green insect.
- Incorrect stress on the first word (should be EM-er-ald).
