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

For example, for 10 larvae: provide a 5L box.

For the nymphs : Once in the shell, you can either leave them in the same box as the larvae or transfer them to another ventilated container. To do this, you will need to reposition the shell in the substrate.

For adults: Provide a terrarium adapted to the number of individuals. For 3/4 couples, provide a terrarium of approximately 40x30x30 (LxWxH) with ventilation on the lid. Also provide approximately 10cm minimum of substrate and small branches for movement.

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 larvae 20 to 30°C and up to 35°C locally for adults to encourage mating.

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: Lighting necessary for adults (bulb, spotlight, tube... if possible slightly heated) A lack of light can reduce or even make reproductions disappear.

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: Pachnoda sinuata love pollen. It can therefore be added to fruits (mainly bananas) or to beetle jelly. Renew as often as possible as soon as the food begins to deteriorate.
