Hacienda Chichen Resort beside Chichén Itzá Ruins, central Yucatán, MÉXICO
Until I began looking closely at our butterflies here I'd always thought that butterflies in the family embracing the skippers -- family Hesperiidae -- were nearly always dark brown or blackish. However, lately we've been running into various predominantly white ones, and this week butterfly identifier Bea in Ontario says that we have a new one, the one shown above.
That's the Turk's-cap White-Skipper, HELIOPETES MACAIRA, distributed from southern Texas south through Mexico and Central America to Paraguay in South America. Its habitat is described as forest edges and openings, thorn-scrub, weedy areas and brush, which is the setting of the hut where I took its picture drinking from a flowerbed I'd just watered. Caterpillars of this species feed on the young leaves, flowers and fruits of Turk's-cap Hibiscuses, or Tulipanes, of the Hibiscus-Family genus Malvaviscus, of which we have very many here.
