This study aimed to obtain information about the fauna composition standards, community structure and Chrysomelidae seasonality in an orchard located in Campos Gerais region of Paraná. During the nearly two years of sampling, 3,361 coleopterous were collected, and among these coleopterous, 1,103 belonged to Chrysomelidae family, representing 30.1% of the captured beetles. Eumolpinae and Galerucinae subfamilies showed the biggest species abundance and richness, furthermore, the most representative to the orchard were: Eumolpinae sp. 7 and Eumolpinae sp. 15, Diabrotica speciosa, Iphimeis dives, Spintherophyta semiaurata, Colaspis sp. 1 and Colaspis sp. 2 and Syphrea sp. 1, representing 91.7% of the collected coleopterous. In relation to the fruit trees, it was observed that the biggest insect number was collected on the orange and tangerine trees; orange tree had the biggest species richness index and persimmon tree showed the biggest diversity index. There was a considerable reduction of the Chrysomelidae species on the second annual cycle, and this fact demonstrated that the family has a great temporal variation. Spring was the season with the largest abundance on two years of collection and the meteorological factors did not show any relation to the Chrysomelidae abundance.
