Fiji Moth

A day-flying forester moth endemic to Fiji, with metallic blue-black wings. It is found in native forest where its larvae feed on native vines. The bright metallic colouration suggests it may be chemically defended.

💡

Did You Know?

The metallic blue sheen of this moth's wings is produced by nanoscale structures rather than pigments, making the colour unfadeable even in museum specimens.

Euthalia Flower Beetle

A beautifully iridescent flower beetle with emerald green elytra and yellow-orange head markings. It frequents forest clearings where it feeds on fermenting fruit. Sexual dimorphism is moderate.

💡

Did You Know?

The metallic coloration is produced by microscopic structures in the cuticle that reflect light, not by pigments.
