For larvae : Plastic boxes with ventilation. Provide a quantity of substrate adapted to the number of larvae.

For example, for 10 larvae: provide a 10L box.

For adults: Provide a terrarium adapted to the number of individuals. For 1 or 2 couples, provide a glass tank of 40x30x40 (LxWxH) with ventilation on the lid. Also provide about 15cm of substrate. Also provide small branches for moving around.

The ground should not be completely flat because the beetles that fall on their backs die quickly because they can no longer turn around. It is therefore very important to fill it with bark, stones or other materials and not to flatten the substrate.

Temperature: for optimal conditions 23/24°C but breeding possible between 20°C and 28°C.

Humidity:

For larvae: provide a slightly damp substrate.

During pupation: provide a slightly drier substrate.

For adults: Provide a slightly damp substrate. If the terrarium is well ventilated, provide a small spray of water every 2 to 3 days.

Lighting: Classic lighting required for adults (bulb, spotlight, tube, etc.)

For larvae: Classic flower beetle substrate: decomposed and crushed oak, beech or possibly chestnut leaves. The larvae are saproxylophagous and feed on decomposing materials (wood, leaves). If the larvae lack food, there is a risk of dying them or obtaining small specimens. The substrate will need to be renewed as soon as there is too much excrement.

For adults: Fruits (mainly banana) or beetle jelly. Possible supplement with pollen. To be renewed as often as possible as soon as the food begins to deteriorate.
