Definition
Pollanisus commoni is a species of day‑flying moth in the family Zygaenidae, endemic to Australia.
Overview
Pollanisus commoni belongs to the genus Pollanisus, which comprises small, metallic‑coloured moths that are active during daylight. The species was formally described in the mid‑1990s and is known from eastern Australian states, primarily New South Wales and Queensland. Adults are typically observed in warm, sunny weather and are attracted to flowering plants where they feed on nectar.
Etymology/Origin
The specific epithet commoni honours the Australian lepidopterist Ian F. B. Common, recognized for his extensive contributions to the study of moths and butterflies.
Characteristics
- Morphology: Adults have a wingspan of approximately 10–15 mm. The forewings exhibit a metallic green to bronze sheen, while the hindwings are usually a brighter orange‑red with a translucent basal area.
- Life cycle: Like other Zygaenidae, P. commoni undergoes complete metamorphosis (egg → larva → pupa → adult). Larvae are believed to feed on low‑lying shrubs in the family Myrtaceae, though specific host‑plant records for this species are not fully documented.
- Behavior: The species is diurnal, often seen basking on sunlit foliage. Adults are capable of short, rapid flights and are occasionally observed visiting garden flowers.
- Distribution: Confirmed records are limited to coastal and sub‑coastal habitats in southeastern Australia, especially in heathland and dry sclerophyll forest ecosystems.

Note: While the existence of Pollanisus commoni is supported by taxonomic literature, detailed ecological data such as precise larval host plants and full distribution range remain limited.
