-Glassy-winged Skipper (Xenophanes ruatanensis)


The genus Xenophanes is instantly recognizable, with a pale brown ground colour heavily speckled with greyish; and large hyaline windows in the fore and hind wings. . The adults are normally encountered singly or in two's and three's. They bask on bushes and low herbage with wings fully outspread but rarely spend more than a few seconds in one place.

Diet

  • The larval food plants of Xenophanes ruatanensis are members of the mallow family (Malvaceae).

  • Adults visit flowers for nectar and may also obtain nutrients from damp ground and other moist surfaces.

Range

  • Xenophanes ruatanensis is a tropical and subtropical species ranging from southern Texas and Mexico through Central America to Costa Rica.

  • Guerrero is within its range, and it occurs in the Zihua region. The Guerrero connection is particularly well supported by genomic examination of material from the state.

Habitat

  • It inhabits tropical dry forest, humid forest, woodland edges, roadside vegetation, clearings and secondary growth.

  • In Costa Rica, larvae have been found in both dry and wet forest environments, particularly in open areas such as roadsides and brushy clearings.

  • In the Zihua region, suitable habitat includes tropical dry forest, thorn scrub, open woodland and disturbed vegetation where Malvaceae host plants occur.

  • Adults are often encountered in open areas and along forest edges, where they perch on vegetation with the wings spread.

Description

  • A small to medium-sized skipper with a wingspan of approximately 30–33 mm.

  • The wings are predominantly brown, with large translucent or glass-like patches occupying much of the median areas of both the forewings and hindwings.

  • The forewing apex and hindwing tornus are pointed, while a series of translucent spots occurs near the forewing apex.

  • The distinctive translucent wing markings give the species its common name, Glassy-winged Skipper.
