CARE NOTES

Keeping considerations

Maintain a 26°C baseline with strong vertical climbing options, a gentle night drop to 20–22°C, and a transition from 60% humidity in early stages down to drier conditions for adults

PRACTICAL HUSBANDRY

Day-to-day care

Diet & prey

Green/blue bottles, locusts, roaches, curly-wing flies, and fruit flies for nymphs

Feeding

Adults benefit from larger prey items every 2 to 3 days; nymphs require small daily meals while keeping enclosures from getting waterlogged

Enclosure

Vertical arboreal setup with branches and bark for climbing and ambush hunting

Substrate

Standard clean substrate keeping appropriate moisture levels without stagnant air

Ventilation

High cross-ventilation or good airflow, especially as humidity is dropped for older instars

Hydration & misting

Daily fine misting for young nymphs; drier ambient air for older stages with external drinking sessions (fine-misted houseplant or droplets) every few days

Handling

Fast and high-strung; best treated as an active display mantis rather than a handled pet

Sex differences

Clear from i5 onward—males have thicker/longer antennae, longer wings, and a slender build (living ~8 months), while females are heavier, more compact, and larger (living ~13 months)

IMPORTANT CONSIDERATIONS

Keeper notes

Highly aggressive hunters; strictly solitary past early instars to prevent cannibalism

BREEDING & LIFE CYCLE

Breeding notes

High female aggression requires careful pairing supervision; oothecae are deposited on vertical surfaces and hatch after a warm, moderate-humidity incubation period
