Giant African flower beetle

Mecynorrhina torquata includes traded subspecies and lines. Retain the exact breeding record rather than inferring it from adult colour.

Confirm the exact subspecies.

Plan separate larval food-substrate and adult housing systems before buying grubs.

Arrange dependable holiday care and keep money available for food, replacement equipment and appropriate veterinary help. Test the habitat before the animal arrives.

Use individual larval vessels with several litres of suitable food substrate; the breeder proposes at least three litres each. Adults need a secure ventilated display with climbing grip, feeding stations and appropriate laying substrate.

Measure usable internal space after substrate, guards and furnishings. Check ventilation, cable holes and access against the smallest occupant. Fix heavy furnishings independently of loose substrate.

Assess the adult group and housing fit separately from larval accommodation.

The breeder uses 22–26°C. Measure within the larval substrate as well as enclosure air, and avoid warming a fermenting medium.

Record the warm and cool locations, overnight minimum and daytime maximum. Air, surface and substrate readings are different measurements. Any added heater needs compatible thermostatic control and safe separation from the animal; assess summer cooling as well as winter heating.

Adults need a normal daytime rhythm and usable climbing space; no mandatory UVB target was established. Do not overheat the substrate with display lamps.

Keep the night dark and provide retreat from daytime light. Lamp percentage, electrical wattage and a product name cannot establish the exposure reaching an animal. Check the finished installation after changes to mesh, branches or lamp position.

Keep nutritious substrate damp and aerated, not saturated. Adults need drier surfaces and safe access to food moisture.

Inspect the occupied refuge and substrate as well as the air reading. Adjust water provision and ventilation together, and clean contaminated drinking surfaces. A single humidity number cannot describe every microclimate.

Larvae consume suitable fermented/decayed hardwood-based food substrate; adults use beetle jelly and appropriate soft fruit. Adult jelly does not feed the larval stage.

Record what is actually eaten and follow changes in growth and body condition. Food size, life stage and the full diet matter. Supplement products require an individual plan; do not combine calcium, vitamin D and multivitamins by guesswork.

Check the larval food-substrate recipe and volume; this does not guarantee breeding success.

Provide several feeding stations and separate fighting adults. Do not break open a pupal cell for viewing.

Make necessary maintenance predictable and allow voluntary retreat. Prepare a secure transfer container before essential moves. Observation should not repeatedly interrupt feeding, rest or moulting.

Review larval growth and substrate conversion to frass without repeatedly disturbing pupation.

Keep dated observations of appetite, activity and condition. A sudden decline, injury, abnormal breathing or repeated failed moults needs appropriate professional assessment. This guide does not provide a diagnosis or medicine dose.

Keep subspecies/line and stage records, and contain eggs and emerging adults.

Ask for a dated source record, scientific identity, life stage and established care history. Keep new arrivals and their equipment separate while an appropriate quarantine plan is agreed. Check current official rules for the exact animal, route and transaction before importing or buying; this page does not establish legal clearance. Never release animals or viable eggs outdoors.

Check adult food hygiene or larval vessel security and temperature, according to stage. Review larval food volume and avoid disrupting established pupal cells. Keep a dated record of measurements and observations, and revisit the full advice when conditions or life stage change.
