Sphinx moths are larger than most moths and the White-lined Sphinx Moth is no exception. Their forewings are mostly brown, but each has a thick white line that extends from the base by the head out toward the tip of the wing. Thin white lines cross this thicker one in spaced intervals from left to right. The tops of the hindwings have a flash of bright pink that is only visible when the moth completely spreads its forewings open.
The caterpillar comes in a wide variety of colors. The immature caterpillar is known to feed on a large variety of plants, but more mature ones tend to prefer evening primrose and roses. A more mature caterpillar is horned and can be black with yellow lines on the sides.

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the White-lined Sphinx Moth may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects 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. States/Territories shown above are a general indicator of areas inhabited by the White-lined Sphinx Moth. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
