TAXONOMY:

Superfamily: Bombycoidea, Latreille, 1802
Family: Saturniidae, Boisduval, [1837] 1834
Subfamily: Hemileucinae, Grote & Robinson, 1866
Tribe: Hemileucini, Grote & Robinson, 1866
Genus: Hidripa, Draudt, 1929

DISTRIBUTION:

Hidripa paranensis (wingspan: males: 51-67mm; females: 64-79mm) flies in
southeastern Brazil: Sao Paulo, Parana, Santa Catarina: Alfredo Wagner (AC); and
possibly into Peru (very doubtful).

Brazil: Parana: Joinville: Guaratuba, dirtroad to Castelhanos village (right turn + ca.3 km), 2008-09-02.

Ezequiel Osvaldo Núñez Bustos sent me a paper in August 2015 which includes Hidripa paranensis in northeastern Argentina: Misiones: Iguazu. I would not be surprised if the specimen indicated as paranensis is actually one of the recently (2015) described species from Argentina: Misiones: perdmisionesa or tagmisonesa. (Bill Oehlke)

The image below was sent to me as weymeri = paranensis from Brazil. It looks more like the species Lemaire depicts as albipellis, which supposedly does not fly in Brazil.

Lemaire indicates paranensis should have yellow around the hindwing eyespot. He indicates reduced yellow for albipellis as evident in the image from Eric van Schayck.

Other characters (much less contrast) also seem a good match for albipellis.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

There are at least three broods annually with peak flights in January-February, April-June, and September-October-November (AC). Larval hosts are unknown.

ECLOSION, SCENTING AND MATING:

Females extend a scent gland from the tip of the abdomen, and the night-flying males detect and track the airbourne pheromone plume with their well-developed antennae.

EGGS, LARVAE, COCOONS AND PUPAE:

Eggs are probably deposited in clusters on hostplant foliage.

Hidripa paranensis larvae are highly gregarious and have the urticating spines typical of larvae from the Subfamily Hemileucinae.

Larval Food Plants


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.
