The male forewing is quite pointed with an orangey-beige ground colour, turning to purplish-brown in the basal and post median areas. The fw discal cell is diffusely outlined in black. The thin postmedian line is concave or even slightly angled. The hindwing is an almost uniform brown-rose with a very diffuse grey cell spot.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Adeloneivaia subangulata subangulata flies in at least two distinct broods in January - February and then again in May-June. Peter Bruce-Jones reports a June 14-15 flight in Shima, Junin, Peru, at 700m.

Nigel Voaden reports a late March flight in Cachoeiras de Macacu, Rio de Janeiro, Brazil.

In Rio Grande do Sul, Brazil, larvae feed on Moraceae and Salicaceae, with adult flights in January-March and September-December.

Larvae feed upon Salix caprea and mimosa. In Europe, Bernhard Wenczel reports Robinia pseudoacacia and Salix caprea are used with some success.

Eurides Furtado reports Anadenanthera falcata as a natural host in central Brazil.

ECLOSION, SCENTING AND MATING:

Adult Adeloneivaia subangulata subangulata moths emerge from subterranean pupae, and males are slightly smaller than females and the wings of the males are more falcate than those of the females. I am pretty sure the female has a dark grey, almost black, dorsal abdominal surface.

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

A light rainfall or mist seems to stimulate additional flight or eclosions resulting in more moths on the wing, or at least taken at lights, but overall this species is infrequent at lights and very irratic in flight when approaching.

In southeastern Brazil this species is sympatric with Adeloneivaia catharina. A. catharina has a pale orange forewing basal median underside, while the same area on A. subangulata is a deep pinkish-red.

EGGS, LARVAE AND PUPAE:

Night-flying females lay translucent green 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.
