The blue pororó (Hamadryas Arete) is an uncommon species, present in shaded areas of ombrophilous forests, and can be seen crossing sunny areas. Despite belonging to the group of snapper butterflies, individuals of the species do not produce the sound when moving. With fast and irregular flight, the butterfly flies over the plant that is going to feed and begins to fly in circles more slowly. It also feeds on ripe fruits that have fallen to the forest floor. The caterpillar of the blue pororo has a black body with alternating green and orange stripes. The body is covered in black spines and the head has branched horns. They have diurnal habits.
