Description

Beetle, Lamprima adolphinae, Iridescent green Stag beetle, mounted in a glass dome.

This beetle has been mounted in an aproximately  2 X 3 1/2 inch glass dome.  You will receive this specimen or one like it.

Lamprima adolphinae is one of Indonesia’s most dazzling stag beetles, a species that looks as though it has been cast from polished metal. Belonging to the Lucanidae family, this beetle is admired for its brilliant emerald-green iridescence, a color produced not by pigment but by microscopic structures in the cuticle that refract light—giving the beetle a shimmering, shifting glow as it moves.

Native mainly to New Guinea and nearby Indonesian islands, this species thrives in humid forest environments where decaying wood is abundant. Like other stag beetles, its larvae are wood decomposers, feeding on rotting logs and contributing to nutrient recycling in the forest ecosystem. Adults typically emerge during wetter months and are often encountered on tree trunks or near sap flows.

Males feature elongated mandibles, though they are more modest compared to the gigantic jaws of some other lucanids. These mandibles are used for male–male competition, but they also help define the species’ elegant silhouette. Females lack the exaggerated jaws but share the same brilliant metallic coloration, often displaying hints of gold or turquoise depending on lighting.

Collectors value Lamprima adolphinae for its combination of rarity, natural beauty, and the scientific intrigue of its structural coloration. It embodies the tropical forests’ incredible ability to produce organisms that seem almost crafted by a jeweler’s hand.
