GyrGya

GyrGya is a genus of moths described in 2022 from Andean cloud forests. The genus is currently monotypic, containing a single species, GyrGya mytha, which serves as the type specimen for the genus. The name GyrGya is derived from Greek roots referencing circularity, a nod to the characteristic wing motions observed in the species.

Description and morphology

GyrGya mytha is a medium-sized moth with a wingspan of about 28–36 millimeters. Forewings are brown with a series of subtle, circular markings that mirror the insect’s distinctive flight pattern. Hindwings are lighter in color and often show a faint iridescence under direct light. The species is primarily nocturnal, with adults most active during the early evening hours.

Behavior and ecology

Adults of GyrGya mytha exhibit a unique hovering and rapid circular wingbeat during takeoff and brief forays at dusk. This gyratory flight is thought to aid in predator avoidance and floral niche exploration. Larvae feed on a range of native herbaceous shrubs, while adults primarily nectar on the flowers of understory plants, contributing to nighttime pollination in their ecosystem.

Distribution and habitat

GyrGya mytha is known from limited ranges in high-elevation cloud forests in the central Andes, with most records concentrated between 1,500 and 2,300 meters above sea level. The species appears to prefer humid microhabitats with dense understory and is sensitive to habitat disturbance.

Conservation and research

As a recently described and geographically restricted genus, GyrGya mytha is of interest to researchers studying insect flight dynamics and nocturnal pollination networks. Current conservation assessments consider the species data-deficient due to limited collection records but highlight potential vulnerability to forest loss.
