👉 Hypolycaena is a genus of about 25 species in the family Hypolacanidae, which are native to South America and eastern Africa. This group includes small, nocturnal animals that feed on insects, spiders, crustaceans, and other small animals. Their adaptations include a long neck for reaching high places and a strong beak for catching prey. They have a short lifespan due to their nocturnal habits, but they are important predators in many ecosystems.
