Amaurodes passerinii linnei
(Schaum, 1844)
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Coleoptera
Family: Scarabaeidae
Subfamily: Cetoniinae
Genus: Amaurodes
Amaurodes passerinii linnei is a very beautiful species measuring about 30 to 40 mm. Its body is black with yellow punctuation, the whole with a downy appearance. Its pronotum is beige with a black band. The metatibias are red.
The larvae are a little different from other species of flower beetle , they are much less soft, not very mobile and have a black head. The substrate sticks to their hairs, the larvae are difficult to find at birth.
It is found in Tanzania and Kenya.

Special features:
Species not recommended for beginners.
- Breeding larvae: very high risk of cannibalism
- Pay attention to humidity during the nymphal phase: species very sensitive to excess humidity and lack of ventilation.
- Long nymphal phase. Once the last moult has been completed, the adult can remain in the shell for a few months before emerging.
The larvae are sent in individual boxes to avoid cannibalism during transport. As a result, shipping costs are higher than for other species.
What you might need:
01. Breeding
For larvae : Plastic boxes with ventilation. We recommend using our micro-perforated boxes , placing one larva per box.
For the nymphs : Once in the shell, you can leave it in the same box and remove some substrate in order to have a partially empty box and the shell.
For adults: Provide a terrarium adapted to the number of individuals. For 1 or 2 couples, provide a terrarium of approximately 40x30x40 (LxWxH) with ventilation on the lid. Also provide approximately 15-20cm MINIMUM of substrate. Remember to add branches for movement because this species is very active.

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: Around 25°C.
Humidity:
For larvae: Provide a slightly damp substrate.
During pupation: Provide a 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: Conventional lighting required for adults (bulb, spotlight, tube, etc.) 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 killing them or of obtaining small specimens. The substrate will need to be renewed as soon as there is too much excrement. This species seems to appreciate a protein intake.
For adults: Fruits (mainly banana) or beetle jelly. Renew as often as possible as soon as the food starts to deteriorate.
Incubation
2 to 3 weeks
Development
5 to 7 months
Nymphosis
3 to 6 months
Imago lifespan
4 to 5 months
02. Please note
Sexing: Sexing adult Amaurodes passerinii linnei is easy since males have a clearly visible forked horn. Females are slightly smaller than males and do not have a horn.
Prolificacy, mating and laying: Low prolificacy.
Cannibalism: Very high risk of cannibalism.
