Resumo: One of the major pests of nursery seedlings of coffee (Coffea arabica L.) is the green scale, Coccus viridis (Green) (Hemiptera: Coccidae). The main predators of this species are beetles of the family Coccinellidae, especially Azya luteipes Mulsant. Morphological, behavioral and biological aspects of A. luteipes feeding on C. viridis on coffee plants were examined under laboratory conditions. Tests were conducted in room temperature at 28 ± 2 ºC. A. luteipes oviposits on the underside of the scale's body, laying two to four eggs per insect. The eggs have a subelliptical form and a white-clear color, and the incubation period is 8.3 ± 1.2 days. The number of eggs laid per female per day varies between eight and ten. A. luteipes undergoes four larval instars with durations of 2.0 ± 0, 3.2 ± 0.5, 3.6 ± 0.5 and 4.6 ± 0 days for the 1st, 2nd, 3rd and 4th instars, respectively. The average durations of the prepupal and pupal stages were 2.0 ± 0 and 10.9 ± 1.3 days, respectively. The viability of the larvae during each instar was 91.9, 89.3, 90.2 and 96.4 %, respectively, and the viabilities of prepupae and pupae were 99.1 and 98.2 %. The average duration of the egg-adult cycle was 34.3 ± 2.6 days, and the sex ratio was 0.52 %. Females presented a gray-colored head, while males presented a yellow head.
