can be difficult to tell apart, requiring close examination of the
Only 4 Emesis species have a falcate
apex to the forewings - angularis,
and tenedia. The first two have an
angular tornus on the hindwings, narrowing the identification of the
illustrated insect to two near-identical 'sister' species
tenedia. Both are subject to variation in their markings, and
their distribution ranges overlap, so it can sometimes be difficult
to tell them apart, but tegula tends to
have more conspicuous dark bands.
Emesis tegula is a largely Central
American species found from Mexico to Colombia.
This species occurs in primary and secondary forest, at elevations
between about 100-900m.
The eggs of
Emesis species are typically white and
highly sculptured. They are laid singly or in clusters of up to 30,
according to species. The known larval foodplants encompass the
families Ranunculaceae, Euphorbiaceae, Rhizophoraceae,
Sterculiaceae, Anacardiaceae and Nyctaginaceae.
