Sphodromantis lineola
The African lined mantis — a tough, reliable feeder and an excellent beginner species.
About Sphodromantis lineola
Sphodromantis lineola is a large, sturdy mantis found across sub-Saharan Africa. It comes in two colour forms — green and brown — both of which can appear in the same egg case (ootheca). The colour is fixed after the final moult and cannot change.
Like all mantids, S. lineola undergoes incomplete metamorphosis: nymphs hatch from the ootheca as tiny replicas of the adult and grow through a series of moults. There is no pupal stage. Total lifespan is approximately 12 months.
This species has a well-deserved reputation as a confident, aggressive feeder. It rarely refuses food and will take on surprisingly large prey items. That assertiveness makes it one of the most rewarding beginner mantids.
Enclosure
Enclosure height is the single most important factor. Mantids hang upside-down from the ceiling to moult, and the enclosure must provide at least three times the mantis's body length in vertical space. For adults, this means a minimum of 27 cm tall.
The ceiling must be mesh or otherwise textured — never smooth glass or plastic. A mantis that cannot grip the ceiling will fall during moulting, which is almost always fatal.
- Mesh pop-up cages, tall plastic containers with mesh lids, or glass terrariums with gauze tops all work
- Provide branches and twigs for climbing and ambush perches
- House individually — mantids are solitary predators and cannibalism is normal behaviour, not a sign of hunger
Temperature, humidity & misting
S. lineola is tolerant of a wide range. Aim for 22–28°C during the day. Room temperature in heated homes is usually sufficient; a heat mat on the side of the enclosure can help in cooler months.
Mist one side of the enclosure lightly every 1–2 days. The mantis will drink water droplets from the walls and mesh. Target 50–70% humidity. This species handles drier conditions better than many tropical mantids, but do not allow the enclosure to become completely arid.
Feeding
Live prey only. Mantids will not scavenge dead insects. Prey should be roughly the length of the mantis's raptorial forelegs — the specialised grasping limbs that define the order Mantodea.
- Small nymphs: fruit flies (Drosophila melanogaster, then D. hydei)
- Medium nymphs: houseflies, small crickets
- Adults: locusts, large crickets, bluebottle flies, moths
Feed every 2–3 days. Avoid overfeeding — a distended abdomen significantly increases the risk of a failed moult. If the abdomen looks drum-tight, skip feeding until it slims down.
Moulting & breeding
Pre-moult signs: food refusal, lethargy, and prolonged upside-down hanging. Never disturb a moulting mantis or mist directly onto it. After moulting, wait 24–48 hours before offering food.
Breeding is straightforward but carries risk. Sexual cannibalism is a real and normal part of mantis reproductive behaviour — the female frequently kills and eats the male during or after mating. Ensure the female is very well-fed before introducing the male, and be prepared for losses.
