Leaf Mimic Katydids: "Peacock Katydid" (Pterochroza ocellata) to the left and a yellow leaf mimic (Cycloptera sp.), right, Loreto, Peru

Trying really hard to look like a leaf and doing a good job of it. The disguise includes leaf veins, moldy spots, and 'holes' in the wings. These outstanding leaf mimicking katydids from the Amazon (photographed on the main branch of the Amazon River, Loreto, Peru, November 2019) wear convincing disguises: The 'Peacock Katydid' (Pterochroza ocellata) to the left and a yellow leaf mimic (Cycloptera sp.) to the right. The 'Peacock Katydid' (Pterochroza ocellata) enacts a threat display. When faced with a potential predator, this katydid arranges its wings such that the eye spots on the ends of the wings are exposed - presenting a potential predator with, what appears to be, the eyes of a much larger animal.
