Abstract
Epuraea domina Reitter (Coleoptera: Nitidulidae) is a flower-visiting insect and a pest that causes corky scar on citrus fruit. This study was conducted to investigate the life cycle of E. domina in a citrus grove. E. domina showed the characteristics of cold breeders as they complete key life history events of oviposition and immature development during the winter. E. domina adults spent the summer in uncultivated habits started to lay eggs in soil near fallen citrus fruit in orchards during late autumn. Oviposition activity continued throughout the winter with a large decrease in activity when the minimum air temperature was <0 °C. Hatched larvae fed on decaying citrus and pupated in soil in the spring. The pupae emerged as new adults in mid-May to feed on the pollen and nectar of citrus flowers, probably followed by their migration to uncultivated habitats in the summer.
