The hefty Leaf-footed Bug has a wide, prominent carapace (shoulder region) that somewhat resembles armor. The males of this large, plant-eating family have unusually thick thighs, often edged with spikes. Their lower legs may also be flat and shaped somewhat like a dried leaf. These parts of the leg are used to fight other males in order to win a female to mate with. Leaf-Footed Bugs may be heard when they fly. A foul odor can also be emitted as a defensive adaptation. Adults fly very well, and dash away if approached.
Nymphs feed on ash trees and other plants. They have flared and spiky abdomens that may curl upward when approached. Without wings at this younger life stage, they resemble the nymphs of Assassin Bugs.

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Leaf-footed Bug 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 Leaf-footed Bug. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
