Pompelon is a monotypic moth genus in the family Zygaenidae erected by Francis Walker in 1854.

It is a day-flying moth found throughout Southeast Asia, with sightings in the Philippines, Myanmar, Thailand, Sulawesi, Borneo, Peninsular Malaysia, Singapore, and Sumatra.

[3] P. marginata is a mid-sized day-flying moth with predominantly black and rounded wings, with iridescent blue margins.

Its body stands in stark contrast to its dark dorsal side, having a bright red thorax and abdomen.

When disturbed, the larva emits a clear liquid, potentially serving as a defense mechanism against predation.
