The cockchafer, colloquially called Maybug, Maybeetle, or doodlebug, is the name given to any of the European beetles of the genus Melolontha, in the family Scarabaeidae. Once abundant throughout Europe and a major pest in the periodical years of "mass flight", it had been nearly eradicated in the middle of the 20th century through the agricultural intensification and has even been locally exterminated in many regions. However, since pest control was increasingly regulated in the 1980s, its numbers have started to grow again.
