A beautifully refined, jewel‑toned flower beetle that’s both striking and easy to keep.
 
Protaetia speciosa jousellini is a wonderfully elegant Asian flower beetle, instantly catching the eye with its deep emerald‑green sheen and smooth, lacquer‑like finish. Under natural light, adults often show subtle gold or blue highlights, giving them a premium, almost “polished metal” appearance that stands out beautifully in any display setup. Their compact shape and confident movement make them a pleasure to watch, whether feeding, exploring, or interacting with other beetles.
 
This subspecies originates from warm, forested regions of East and Southeast Asia, where adults spend their time visiting flowers, feeding on fruit, and moving through leaf litter. In captivity, they’re gentle, active, and very easy to manage. Adults feed readily on beetle jelly, soft fruits, and nectar‑style foods, and they settle quickly into routine care. They’re strong fliers but not skittish, making them suitable for both display enclosures and breeding setups.
 
Larvae grow steadily in nutrient‑rich flake soil or leaf litter mixes, forming firm, reliable pupation cells when moisture is kept stable. Development is smooth and predictable, making this species a great choice for keepers who enjoy raising beetles through their full life cycle. Once emerged, adults are hardy, long‑lived, and show off their glossy colours beautifully.
 
With its jewel‑like appearance, calm temperament, and dependable breeding habits, Protaetia speciosa jousellini is an excellent option for both new and experienced keepers looking for a visually impressive yet straightforward flower beetle species.
