A polyp or abnormal growth occurring on or affecting the elytra (hardened wings of beetles).
Combines 'elytron' (beetle wing cover) + 'polypus' from Greek 'polypous' meaning many-footed, used medically for fungal or tumor-like growths that spread.
Ancient doctors called growths 'polyps' because early ones resembled tiny octopuses, and scientists later borrowed this vivid word for any abnormal tissue growth, even on insect wings!
