Idolomantis diabolica
An East African species and one of the largest flower-mimicking mantises. Adults are striped white and green with red, blue and purple threat colours. Needs high heat, humidity with ventilation and a flies-only diet; the hardest mantis to keep.
The devil's flower mantis (Idolomantis diabolica) is a large empusid from East Africa, from Ethiopia to Tanzania, and the only species in its genus. Females reach about 13cm and males about 10cm, making it the largest flower-mimicking mantis. Nymphs are dead-leaf coloured, while adults turn white with green stripes and flash red, white, blue, purple and black on the forelegs and wings when threatened. In the wild it takes only flying insects such as butterflies and flies. Captive care requires daytime temperatures of 32-40C with high humidity and plenty of ventilation, and food limited to flies and moths. It is skittish, easily stressed by disturbance or too many prey insects, and whole groups are often lost to moulting failures. It cannot walk on glass, so use mesh cages or enclosures with many branches. Males mature after about seven moults and females after eight; an ootheca holds 10-50 eggs and hatches in roughly 50 days. Its difficulty and price make it a prestige species, with thousands traded in Europe and North America each year.

Humidity
60〜80%
Flying insects only such as flies and moths (fruit flies for nymphs)
Keep 32-40C by day (around 35C) with a bulb and let it drop to about 20C at night. Maintain high humidity with strong ventilation: open the cage by day and mist in the evening.
Mature 2-4 weeks after the final moult. Females lay several oothecae at 2-3 week intervals, each with 10-50 eggs hatching in about 50 days. In captivity the female often eats the male's head during mating.
Because it hunts only flying prey, cannibalism is relatively rare and groups can share a large cage. Adults will eat nymphs of their own species, so move the parents before the ootheca hatches.
Lifespan is typically about 12 months. Males mature after about seven moults and females after eight; growth speed depends on temperature and humidity.
Feed only flies and moths, never crickets. Do not leave it without prey for more than two days, but do not crowd the cage either. It cannot climb glass, so provide mesh, branches and dry leaves. Moulting failure is the main cause of death.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The average lifespan of Devil's Flower Mantis is About 12 months (typical). With proper care and nutrition, they can live a long and healthy life.
Devil's Flower Mantis typically reaches Females about 13cm, males about 10cm as an adult. Size may vary depending on care conditions and individual genetics.
Devil's Flower Mantis feeds on: Flying insects only such as flies and moths (fruit flies for nymphs). Aim for a balanced diet with appropriate feeding frequency.
