What environment does the Rucker's Flower Beetle need?

Since it's native to Southeast Asia, it does best in a stable indoor environment without sudden temperature or humidity swings. Use a well-ventilated case with substrate, keeping it neither too dry nor too wet.

How can I tell males and females apart?

Males have noticeably longer tarsi on their front legs than females. This difference makes visual sexing straightforward.

Is this a good beetle for a first-time keeper?

This species is generally considered suitable for keepers with some prior experience. Having a basic handle on temperature, humidity, and feeding routines beforehand makes for a smoother start.

What should I watch for when keeping several together?

Males can fight and risk injuring each other's legs or antennae. If housing multiple beetles together, add extra hiding spots or separate the males into different enclosures.

What should adults be fed?

Adults feed mainly on commercial insect jelly. When keeping multiple beetles, set out extra jelly dishes to reduce competition over food.

Rucker's Flower Beetle key facts

Care level: Intermediate
Lifespan: Adults 3-6 months
Size: 25-35mm
Diet: Adults take fruit and beetle jelly; larvae feed on rotten wood and leaf litter
Temperature & Humidity: No published figures for rearing temperature or humidity could be found for this species, so none are given. Its range takes in tropical and subtropical montane forest, so it may prefer cooler conditions than lowland tropical species, but no documented figure was found.
Breeding & Egg-laying: No breeding report for this species could be found. Following the usual method for flower beetles, eggs would be laid into a mix of rotten wood and leaves and the larvae raised in the same medium, but no measured figures for laying conditions or larval period are available for this beetle.
Cohabitation: Adult males fight, so keep them apart except for pairing. No report of cannibalism in the larvae of this species could be found, but individual containers are the safer choice.
Lifespan & Rearing Period: No reliable published figures for larval period or adult lifespan could be found for this species.
Health & Notes: Importing live stock requires the species identification certificate demanded for Scarabaeoidea. Several subspecies exist and the markings run white in some populations and orange in others, so do not cross beetles from different localities.

About Rucker's Flower Beetle

A Southeast Asian flower beetle with a steel-blue head and glossy green elytra marked with white or orange spots. Adults reach 25-35mm; males have longer front tarsi, making sexing straightforward. Best suited to keepers with some experience.

7 things to know before welcoming a Rucker's Flower Beetle

1Enclosure & Substrate
Rucker's Flower Beetles do well in a well-ventilated insect case with substrate kept lightly moist. Avoid letting it dry out completely or become waterlogged — the surface should feel just slightly damp to the touch.
2Temperature & Humidity
As a Southeast Asian species, this beetle has limited cold tolerance. Keep it in a stable indoor environment and avoid sudden temperature swings between seasons.
3Feeding Adults
Adults feed primarily on commercial insect jelly. When keeping several beetles together, provide multiple jelly dishes spaced apart so individuals don't compete over the same feeding spot.
4Telling Males from Females
Males have noticeably longer tarsi on their front legs than females. Learning this distinction makes it easy to sex individuals at a glance, whether at purchase or when planning a pair.
5Housing Multiple Beetles
Two males kept in the same enclosure may fight and risk damaging legs or antennae. If keeping several beetles, separate the males or add plenty of hiding spots to reduce stress.
6Handling Carefully
Handle the beetle gently and avoid pinching its legs or wings. Hold it close to a surface when transferring it, since a fall can damage its wings or legs.
7Preparing Before Arrival
Have the enclosure, substrate, insect jelly, and climbing branches ready before your beetle arrives. Since this species suits keepers with some prior beetle-keeping experience, brushing up on basic care beforehand is a good idea.
