Introduction
The family Sphingidae comprises 200 genera and about 1200 known species worldwide. Eumorpha triangulum has a wide distribution, occurring from Belize and Guatemala to northern Argentina.
Habitats
This species is found in rainforest and cloudforest habitats at altitudes between about 100-1000m.
Lifecycle
Eumorpha triangulum lays its pale green eggs singly on the foodplants Saurauia and Cissus. In the first instar the caterpillar’s thin anal horn is about half of its body length, but becomes shorter in the later instars. The caterpillar turns pinkish just prior to pupation, and pupates just below the surface of the ground. The long thin pupa is brown, shiny, and has a spiky cremaster.
Adult
The adult moth is patterned in shades of olive-brown, and when at rest resembles a bunch of dead leaves. It has a wingspan of about 100-130mm.
