noun any of various large European beetles destructive to vegetation as both larvae and adult
originFrom cock (“male bird”) + chafer (“beetle”). The Oxford English Dictionary speculates that the name may relate to a resemblance of antennae to coxcomb, or to the beetle’s size. Compare French hanneton (“cockchafer”), ultimately from Frankish *hanō (“rooster”). First attested in the late 17th century.
