Lamprima adolphinae, often called the Jewel Stag Beetle, is a striking member of the Lucanidae family found in New Guinea and Papua. Males are especially eye-catching, with metallic hues that can range from emerald green and bronze to vivid gold, blue, or purple. Their elongated mandibles, used in competition for mates, give them the classic stag beetle silhouette, while females are smaller and less flamboyant in coloration.
 
In the wild, these beetles thrive in forested habitats where their larvae feed on decaying wood, playing an important role in nutrient recycling. Adults, meanwhile, are drawn to sweet fruits and tree sap, making them relatively easy to maintain in captivity. Their short development time—often just a few months from egg to adult—combined with their dazzling appearance has made them a favorite among beetle enthusiasts worldwide.
 
For keepers, L. adolphinae is considered one of the more approachable stag beetles to rear. They tolerate room temperatures well, breed readily, and live for several months as adults, providing ample opportunity to appreciate their jewel-like sheen.
