Relating to or characteristic of beetles, which are insects belonging to the order Coleoptera.
The coleopterous species in the garden are known for their hard shells and diverse colors.
Coleopterous → It is formed from "coleo-" (from Greek "koleos", meaning sheath) and "pteron" (meaning wing). The word describes insects that have wings covered by a sheath, specifically beetles.
Think of 'sheath' ('coleo-') covering 'wings' ('pteron') — that's why coleopterous refers to beetles with wing coverings.
