The Esmeralda Longtail (Urbanus esmeraldus) is a vibrant Neotropical skipper butterfly primarily recognized by the iridescent emerald or blue-green tint on its body and wing bases. It belongs to a group of "longtail" skippers that are visually similar, often requiring close inspection of the wing undersides for positive identification. Typically inhabits open subtropical woods, lowland tropical forest edges, forest glades, and disturbed areas like roadsides.
