© Frank Model
There are 41 Emesis
species, all but one of which are confined to the neotropical
region. Several including aurimna,
and toltec occur in Mexico, but only 2
species ares and
zela penetrate beyond the Mexico border to breed in the USA.
Emesis ares is found in Arizona and New
Mexico; and in north-west Mexico.
This species is found in open oak woodland on desert mountains.
The eggs are white.
They are laid singly or in pairs on the twigs or leaves of the
foodplant Quercus ( Fagaceae ). The
caterpillar is brown when newly hatched but when fully grown is pale
green and covered with short white bristly setae. It lives in a
shelter constructed by half-folding a leaf and fastening it with
silk. The pupa is formed on a leaf of the foodplant.
Both sexes nectar at
Eupatorium and various other flowers.
