Lepidopterist → It is formed from "lepidon" (from Greek "lepis", meaning scale) and "pteron" (meaning wing), combined with the suffix "-ist" (meaning one who practices or is concerned with). A lepidopterist is someone who studies or collects butterflies and moths, which are characterized by their scaled wings.
