DISTRIBUTION:

The Ithomisa umbrata moth (wingspan: males: 95mm; females: 114mm) flies in
Brazil: Rio de Janeiro; Sao Paulo.

This may be a dark form of I. catherina. Members of this genus frequently lose many of the darker scales as well as the lighter scales in flight.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Flight season is January-April. Ithomisa umbrata larvae probably eat Paepalanthus polyanthus.

ECLOSION, SCENTING AND MATING:

Day-flying males use well-developed antennae to seek out females which scent during the day but fly at night.

EGGS, LARVAE, COCOONS AND PUPAE:

Typical of species in the Genus Ithomisa and the Subfamily Hemileucinae, the larvae are armed with urticating spines.

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.
