The ocurrence of predator ladybeetles (Coleoptera, Coccinellidae) in an orange orchard, in Montenegro/RS, was verifi ed to follow a seasonal pattern. The monthly samples obtained between January to December of 2002, from 30 trees of an orchard treated ecologicaly, resulted in 14 species of identifi ed coccinelids. In a general way, the coccinelids were more frequent between July to September (Winter season), where 81% are from Coccidophilus citricola Brèthes, 1905. In spite of the large number of individuals that occur on winter, seven from fourteen species presented, individually, population peaks on Spring season.
