Introduction
This species is one of 4 members of the genus Baeotus, all of which are confined to the neotropics.
Habitats
Baeotus japetus breeds in lowland wet tropical forests at altitudes below about 600m, and appears to be largely confined to the upper Amazon areas of Brazil and Peru.
Lifecycle
Unknown. The genus appears to be very closely related to Historis, which suggests that Moraceae and Urticaceae are probable foodplants.
Adult behaviour
The adults are usually seen singly, but sometimes in two’s or three’s, in the company of Baeotus aeilus or B. deucalion. They are regular visitors to patches of mineral-rich damp sand along the beaches of rivers in Amazonia. They have a rapid and powerful flight, and if disturbed, fly up and settle on nearby tree trunks or vegetation, but quickly return to their original feeding spot.
