The White-blotched Heterocampa caterpillar sports a wide variety of appearances. A bright fuchsia pink is perhaps the most conspicuous one. Pink with a pair of purple diamond-like splotches of color on the top is also striking. Other variations blend in better with the surrounding foliage. The white blotches on the top of the body are easy to see on the green or brown caterpillars. The light brown head has a pale midline shaped like a 'V' that extends onto the body. A small, shiny, black orb or red stump sits on either side of the pale midline, like a small pair of eyes on the back of the head.
This species feeds on the leaves of oak trees and can produce many generations in one year in the warmer parts of its range.
The map above showcases (in blue) the states and territories of North America where the White-blotched Heterocampa Caterpillar may be found (but is not limited to). This sort of data can be useful in seeing concentrations of a particular species over the continent as well as revealing possible migratory patterns over a species' given lifespan. Some species are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America.*NOTE: States/Territories shown above are a general indicator of areas inhabited by the White-blotched Heterocampa Caterpillar. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
