It is an insect, specifically a butterfly species (Lasiommata megera).

Can you find wall brown butterflies in the United States?

No, they are native to Europe, North Africa, and parts of Asia. They are not found in the wild in the Americas.

Why is it called a 'wall' brown?

Because it is commonly observed resting on walls, rocks, and other vertical surfaces to bask in the sun.
