- Do not confuse with 'крыло' (wing), which is general. The correct translation is 'надкрылье' (singular), 'надкрылья' (plural).
Common Mistakes

- Using 'elytron' to refer to the wings of butterflies or flies (it's specific to beetles/coleoptera and some true bugs/hemiptera).
- Using it as a countable noun with irregular plural (correct: one elytron, two elytra).

Frequently Asked Questions
The plural is 'elytra'. This follows a Greek-derived pluralisation pattern (similar to criterion/criteria).
No. Elytra are characteristic of beetles (order Coleoptera, which literally means 'sheath-winged') and some true bugs. Butterflies, flies, and bees do not have elytra.
It would be highly unusual and likely confusing. In everyday talk, people might say 'shell' or 'hard back' for a beetle, but the precise term is only needed in scientific discussion.
There is no difference. 'Wing case' is the common English descriptive term, while 'elytron' is the formal, Latinate scientific term. Entomologists use 'elytron/elytra'.
