Euchromia dubia is a species of moth within the subfamily Arctiinae (tiger moths), first described by the German entomologist Johannes Rรถber in 1887. Like other members of the genus Euchromia, it is known for its vivid, aposematic coloration, which serves as a warning to predators of its potential toxicity.

Description and Mimicry ๐
While specific detailed descriptions of E. dubia are rare in general literature, it belongs to a group of moths renowned for wasp mimicry (Batesian mimicry).
- Appearance: They typically feature striking patterns of black, iridescent blue, and vibrant orange or red bands across the abdomen. ๐
- Wings: The wings often contain translucent or “windowed” patches, further enhancing their resemblance to Hymenoptera (wasps and bees).
- Defense: These moths are often pharmacophagous, meaning they seek out and ingest pyrrolizidine alkaloids from plants to make themselves unpalatable to birds and monkeys. ๐
Distribution and Habitat ๐
- Range: This species is primarily found in the Indo-Australian region, with specific documentation on the island of Seram in Indonesia. ๐ฎ๐ฉ
- Habitat: They typically inhabit tropical rainforests and humid rural or agricultural areas where their host plants are abundant.
- Behavior: Unlike many moths, many species in this genus are day-flying (diurnal), relying on sunlight and warmth for activity. โ๏ธ
Lifecycle ๐
- Larvae: The caterpillars typically feed on plants in the family Fabaceae (legumes) or Convolvulaceae (morning glories).
- Metamorphosis: They undergo a complete metamorphosis from a herbivorous caterpillar to a nectar-sipping adult that contributes to local pollination. ๐บ
