Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'лунная моль' (lunnaya mol') which implies a pest. The standard Russian term is 'лунный павлиноглазый сатурний' or, informally, 'лунная бабочка' (lunnaya babochka).
- Do not confuse with 'мотылёк' (motylyok) which is a generic term for a small moth.
Common Mistakes
- Misspelling as 'lunar moth'. While logical, the standard name is 'luna moth'.
- Using it as a generic term for any large, pretty moth (it is one specific species).
- Incorrect pronunciation: /ˈluːnə/ not /ˈlʌnə/.

Luna moths are found in deciduous forests across North America, east of the Great Plains, from Canada to northern Mexico.
