Derby's Flower Beetle (Dicronorhina derbyana)

Dicronorhina derbyana

The Dicronorhina derbyana (Derby's Flower Beetle). It is a medium-large cetonine beetle (up to 2 inches) of dazzling beauty, considered a must-have for those wishing to step up from the very easy Pachnoda to the more important African beetles. The base color is a vivid Emerald Green, Aqua Green or even metallic Purplish (depending on the subspecies, like the 'layardi'), longitudinally furrowed by wide and perfect Chalk-White bands along the entire body. The male is immediately recognizable by the prominent flat and rectangular spatula-shaped frontal horn, which he uses as a small 'bulldozer' in territorial disputes. Formidable diurnal flyers and tireless eaters of sugary fruit, they are extremely active in sunlight. Larvae require a generous base of Flake Soil (rotten wood and oak leaves), but unlike the demanding colossi, they better tolerate humidity fluctuations and have lower cannibalism rates.
