The map above showcases (in blue) the states and territories of North America where the Long-horned Slug 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 Long-horned Slug. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
