In November 2016, Luiz Guilherme Zenóbio Alípio posted the following image from Nova Mutum, Rondonia, Brazil. Ryan St. Laurent identified it as Adeloneivaia boisduvalii, and I agree with that determination. Claude Lemaire had not previously placed it in Rondonia in his great Ceratocampinae work (1988), but indicated it as a Guiano-Amazonian species. Thus the sighting in Rondonia is not surprising.

The forewing ground colour is dark orange in both sexes. The basal and postmedial areas are a pinkish-brown. Males usually have a small double white discal spot on the dorsal surface of forewings, but there is no discal spot or yellow area on the forewing ventral surface.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Adeloneivaia boisduvali flies in at least two distinct broods in February, April-May and August suggesting at least two broods. Luiz Guilherme Zenóbio Alípio reports a November flight in Rondonia, Brazil, suggesting a third annual flight. Vany and Dominique report a September flight in French Guiana.

Larvae feed upon Acacia dealbata.

ECLOSION, SCENTING AND MATING:

Adult Adeloneivaia boisduvalii moths emerge from pupae, and males are considerably smaller than and have more falcate wings than females.

Mating probably begins shortly after dusk with a calling period from 10:30 pm. to 1:00 am.

EGGS, LARVAE AND PUPAE:

Night-flying females lay translucent eggs on host plant leaves.

Larvae pupate underground in small chambers.

Care of larvae and pupae should be as for any Neotropical species.

It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.
