lives in Caribbean climates and its range extends from South America to Central America, and into Mexico. It also spans from the Caribbean to Florida and some of southeastern United States.
The range of this organism is from the Caribbean islands to Florida, and from upper South America into Mexico. Thelives anywhere that the oleander lives naturally, except for California. It flourishes, however, in southern Florida. Its original host plant is thought by many to be the Echites umbellata.
In the larval stage, the oleander caterpillar is a bright orange, much like the flower it is named after. It has bristly black hairs, and is about 3 to 40 mm long. In its adult stage, its body and wings are an incandescent blue-green with white polkadots, and its abdomen is red-orange. It has a wingspan of 45-51mm.
reproduces sexually, mating and laying their eggs on the undersides of the leaves of the oleander. Egg clusters can range from 12 to 75 eggs which are less than 1 mm in diameter. They hatch into larvae that are anywhere between 3 to 44mm. The larval stage is further divided into instars. The first instar hatches in a few days, depending on climatic temperature. The second and third instar eat a great deal and move down the oleander; this stage lasts around 8.5 days on average. The fourth instar is the only one that can eat other parts of the leaf as opposed to just the underside. During the fourth, fifth, and sixth instar, they eat alone. Then they search for a location to pupate. They then become a pupa and are smooth and brown. They are covered in a thin cocoon that they make from silk and their hair. Finally, they hatch into the adult moth. Generally, there are three generations of Syntomeida epilais a year.
When it is time to mate, the femalelets out an ultrasonic acoustic signal that can attract a male moth. Once they are close to each other, they continue calling to each other until a few hours before the sun rises.
This caterpillar's diet consists mainly of the leaves of the oleander plant on which it lives. During the earlier portion of its larval stage, it feeds on the undersides of the leaves, but as it grows into a mature larva, it can consume the entire leaf, except for the veins.
The oleander caterpillar doesn't posess any direct positive attributes for humans. It does, however, contribute to the food chain in many important ways which affect humans.
Because of their "skeletonizing" feeding behavior, they leave the leaf veins alone, but devour the tissue in between. This causes the oleander to be more susceptible to other insects and also causes asthetic damage to the oleander.
The oleander caterpillar is abundant.

rainforests, both temperate and tropical, are dominated by trees often forming a closed canopy with little light reaching the ground. Epiphytes and climbing plants are also abundant. Precipitation is typically not limiting, but may be somewhat seasonal.
A terrestrial biome. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.
A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. See also Tropical savanna and grassland biome.
A terrestrial biome found in temperate latitudes (>23.5° N or S latitude). Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. Fire and grazing are important in the long-term maintenance of grasslands.
