# Orange Virbia Moth (*virbia aurantiaca*)

The Orange Virbia Moth (Virbia aurantiaca) is a delightful and vibrant member of the tiger moth subfamily. Known for its striking contrast of colors, this small moth brings a splash of warm orange to the grassy fields and damp meadows of eastern North America. Unlike many moth species that are strictly nocturnal, the Orange Virbia is frequently active during the day and at dusk, fluttering low through vegetation in search of mates or nectar. Its life cycle is deeply intertwined with various common weeds and wildflowers, making it a vital and fascinating contributor to local grassland ecosystems.

## Appearance

This small moth features a wingspan of approximately 2 to 3 centimeters. Its forewings are typically a muted, earthy shade ranging from yellowish-brown to deep cinnamon, which provides excellent camouflage when resting on leaf litter. In stark contrast, its hindwings are a brilliant, fiery orange or peach-colored hue, boldly bordered with dark charcoal-black markings. The abdomen is also bright orange, warning potential predators of its toxic chemical defenses.
