All specimens of this species were reared from Pelochyta misera ( Erebidae : Arctiinae ). Food plants include Heliocarpus appendiculatus ( Malvaceae ), the introduced species Psidium guajava ( Myrtaceae ), Inga oerstediana , and Erythrina costaricensis ( Fabaceae ). Host caterpillars were collected in June, August, November, and October. Notes. This species has a sexually dimorphic color pattern: females have bicolored wings and a mostly orange mesosoma, while males have infuscate wings and a black mesosoma. Figure 18.
