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.
Purple Emperor
A majestic woodland butterfly whose males display an intense iridescent purple sheen visible only at certain angles. It never visits flowers, preferring carrion, dung, and tree sap.
Did You Know?
Enthusiasts bait it down from the canopy using rotting shrimp, dirty nappies, or Stilton cheese.
