👉 Xenopteri is a genus of butterflies in the family Lycaenidae. They are found throughout much of the world, from tropical Africa to temperate regions like Europe and North America. The specific name "xenopteri" comes from the Greek word "xenos" meaning "unknown," and "opter" which means "wing." So, "Xenopteri" refers to a group of butterflies that are not well-known or known only through their wing shape.
