A Hackberry emperor butterfly stands on gray rocky terrain.
A side view of a Hackberry emperor butterfly standing on a gray rock surface facing the left side of the image. The butterfly has brown wings with black and white spots. The wings are casting a shadow on the rocks below it extending down toward the bottom of the image. Behind the butterfly is a pile of gray rocks extending across the top of the image. The rocks are casting small shadows on rocks below and on the rock surface beneath the pile. The rock surface is rough and uneven, composed of many small rocks packed next to one another.
