Pachnoda butana
A close relative of the sun beetle — similarly easy, similarly rewarding, and often confused with its cousin P. marginata.
About Pachnoda butana
Pachnoda butana is a medium-sized African flower beetle (Cetoniidae) native to Sudan and nearby regions. It is frequently confused with P. marginata in the hobby — both are similar in size and care requirements, though P. butana typically has more orange-brown colouration compared to P. marginata's bright yellow. Both species are excellent beginner beetles.
The full life cycle takes around 6–9 months. Adults are diurnal, active, and entertaining to watch as they fly and feed during the day.
Larval care
Larvae are white C-shaped grubs that feed underground on decaying organic matter. Provide a deep, moist substrate:
- Well-rotted deciduous hardwood mixed with coco coir
- Leaf litter and general organic debris are also acceptable substrate components — this is a forgiving species
- At least 15cm substrate depth
- One larva per litre of substrate as a minimum
- Keep consistently moist — squeeze test: a drop or two of water, no more
Larvae will construct a pupal cell from compacted substrate when ready to pupate. Once they stop moving and begin to darken, do not disturb the substrate. A broken pupal cell is usually fatal. The pupal stage lasts 4–8 weeks.
Adult enclosure & feeding
A ventilated enclosure of roughly 40×30×30cm suits a small group. Provide cork bark and branches for climbing. Adults feed on ripe fruit (banana, mango, peach) and beetle jelly. Replace food every 1–2 days and remove anything mouldy.
For egg-laying, provide 15–20cm of moist rotted wood substrate in the enclosure. Females will burrow down to deposit eggs.
Breeding
P. butana breeds readily in captivity at 24–26°C. Eggs hatch in 2–4 weeks. A female can lay 20–40 eggs. This species reproduces quickly enough that a small colony can sustain itself indefinitely with minimal intervention.
