Brachysternus viridis

(Coleoptera, Scarabaeidae)

ENGLISH: Brachysternus viridis : This is one of the largest and most colorful chilean scarabs. Measures up to 30 mm. It is frequently seen flying at dusk on different species of Fagaceae of the genus Nothofagus. There are several species of this genus surprisingly little studied. Some of them can be collected in very large numbers attracted by light at night. Nothing is known of its biology and life cycle despite its abundance. It is supposed that the larvae live in the ground. It can be found in the areas where are Nothofagus, between Santiago and Osorno, especially from November to February. There are probably several species considered under this name. This group of beetles currently being studied by entomologists at Nebraska University.
