Ruby Tiger Moth

Phragmatobia fuliginosa

Also known as Ruby Tiger

Ruby tiger moths are distinctive day-and-night flyers with translucent rust-red forewings and brilliant carmine hindwings dotted with dark spots. Females emit potent pheromones from low perches at dusk to draw hovering males, producing two broods across most of their temperate range. In late autumn, their bristly black caterpillars often march visibly along paths and roadsides before overwintering under leaf litter or snow.
