Leaf-mimic katydids courting on a leaf. There are two katydids here, with the smaller male riding on the larger female. This is a precursor to possible mating. Katydids are a widespread family of insect related to crickets, and are also known as bush-crickets. The leaf-mimic katydids are found in the neotropics (Central and South America). As their name suggests, they mimic the appearance of leaves. Many species are sexually dimorphic, as here, with the females being larger than the males. Photographed in the Ecuadorian Amazon.
