About
The Daisuke subspecies of the giraffe stag (Prosopocoilus giraffa daisukei) is found on Negros and Sibuyan in the Philippines and is named after the eldest son of describer Tetsuro Mizunuma. Males measure 66-114 mm and females 44-63 mm. Among the nine subspecies it is second in size only to keisukei of Flores, with a wild maximum of 114.0 mm and a captive record of 119.4 mm. Its glossy elytra are characteristic, and Japanese hobbyists call it "Daisuke giraffa". Biology matches the species: it feeds on sap high in rainforest hardwoods and females lay in rotten wood. Larvae pupate 7-14 months after hatching, and adults live 6-15 months, long for the genus. Keep at about 20-26 C, collect eggs from fairly soft logs, and rear larvae in fungus bottles or substrate. The long mandibles pinch weakly but the basal inner teeth are powerful, and stressed males may injure females. The BE-KUWA captive record is 119.4 mm (2009).
