| Eumorpha labruscae (Linnaeus, 1758) |
The Gaudy Sphinx (Eumorpha labruscae) is a moth in the sphingidae family, with a wingspan of 4 5/16 - 4 3/4 inches (11 - 12 cm). Its body and dorsal forewings are a deep green color. The dorsal hindwings have purple-blue patches, yellow borders, and a red spot near the inner margin. The underside is yellow-green and gray-purple. Like most moths in the sphingidae family, caterpillars pupate in underground burrows. Their range is Argentina north through Central America, Mexico, and the West Indies to Florida, Mississippi, South Texas, and Arizona. Ocationaly winds carry them to other places, such as to Missouri, southern Michigan, Pennsylvania, Maine, and southern Saskatchewan.
[edit] Life cycle
Female adults lay their eggs on the leaves of the host plant, mainly Grapes (Vitis), Vine (cissus, and Christmasbush eupatorium (Eupatorium odoratum). Caterpillars hatch and start eating. When they are ready to pupate, they climb down their host plant and burrow underground. When the pupa is ready, it wiggles to the surface just prior to eclosion. The newly emerged adults then climb on a plant or some other surface, and pump fluid into their wings to extend them. Females emit pheromones at night, and males fly into the wind to pick up and track the pheromone plume. Adults probably feed on flower nectar
