Wavy-lined Heterocampa caterpillars are perfect leaf mimics. Their green bodies often have brown patches that resemble dry parts of dying foliage. Some have white, diamond-like marks on the top side, which look like lichen or spots of bird droppings. Some are brown-orange and covered in dark mottling. A pair of black orbs on the back of the head eventually becomes branching antlers that grow forward over the dark brown head. The rear ends in a two short 'tails'.
This species feeds on the leaves of apple, willow, and hickory as well as other deciduous trees.
The map above showcases (in blue) the states and territories of North America where the Wavy-lined Heterocampa Moth 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 Wavy-lined Heterocampa Moth Caterpillar. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
