Cetonischema aeruginosa
( Drury , 1770)
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Coleoptera
Family: Scarabaeidae
Subfamily: Cetoniinae
Genus: Cetonischema
Beautiful shiny green rose chafer with a dazzling shimmer. As adults, they can measure from 2.5 to 3 cm in size.
This species can be found in France, Greece, Albania, Central Europe, and southern Asia Minor.
The reproduction of Cetonischema aeruginosa is quite late and occurs 1 to 2 months after hatching. It is recommended to induce hibernation or rather a diapause at the end of the larval stage to achieve better reproduction and egg laying.
For the larvae: Plastic containers with ventilation. Provide an adequate amount of substrate based on the number of larvae.
For example, for 10 larvae: prepare a 5L container.
For the nymphs: Once in the pupal stage, you can either leave them in the same container as the larvae or transfer them to another ventilated container. To do this, you will need to place the pupae back in substrate.
For the adults: Prepare a terrarium suitable for the number of individuals. For 2/3 pairs, consider a 40x30x30 glass tank (LxWxH) with ventilation on the lid. Also, provide about 10/15cm of substrate. Additionally, provide small branches for movement.
Temperature: for optimal conditions 23/24°C but breeding possible between 20°C and 28°C.
Humidity:
For larvae: provide a slightly humid substrate.
During pupation: provide a slightly drier substrate.
For adults: provide a slightly humid substrate. If the terrarium is well ventilated, consider a light misting every 2 to 3 days.
Lighting: Standard lighting required for adults (bulb, spotlight, tube…)
For the larvae: Classic cetonia substrate: decomposed and crushed oak, beech, or possibly chestnut leaves. The larvae are saproxylophagous and feed on decomposing matter (wood, leaves).
For the adults:Fruits (mainly bananas) or beetle jelly. This species particularly enjoys pollen.
Incubation
ABOUT 1 month
Development
From 7 months to 1 year
"Nymphose" is a French term that refers to nymphomania, a psychiatric disorder characterized by an excessive or insatiable sexual desire in a woman.
1 to 2 months
Adult lifespan
1 year and older
Sexing: The male has its last ventral abdominal segment shaped like a trapezoid with few punctuations. Also, the hind tarsi are the same length as the tibiae.
In contrast, the female has shorter hind tarsi compared to the tibiae. Her last ventral abdominal segment is triangular in shape with more pronounced punctuation.
Fecundity: Medium to high under optimal conditions.
Cannibalism: Absent
It is recommended to induce hibernation or rather diapause at the end of the larval stage to achieve better reproduction and egg-laying.
Larvae at the end of the L3 stage are placed in a drier substrate and in a cooler place at 5-8°C (for example, a wine cellar) for 2-3 months. Then they are returned to the rearing temperature.
