Ask experienced mantis keepers what they would recommend to a complete beginner and most will give the same answer: Sphodromantis viridis, the giant African mantis. It is large enough to watch easily, calm enough to handle without drama, and forgiving enough that the small humidity and temperature wobbles every beginner makes rarely turn fatal.
This guide covers African mantis care from the moment your nymph arrives through to adult life, sexing, and oothecae. If you are still deciding whether to get a mantis at all, our praying mantis care guide gives you a full species comparison to help you choose.
Key Takeaways
- Temperature range of 75-85°F is easy to hit with a low-wattage heat lamp.
- Humidity target is 50-65%: very forgiving compared to tropical species.
- Accepts a wide range of feeder insects — fruit flies at L1-L3, crickets and roaches as adults.
- One of the few mantis species that actively watches its keeper. The head-turning behavior is remarkable.
- Females reach 4 inches and are visually impressive animals.
- Solitary housing is non-negotiable: cannibalism happens at every instar.
Is the African mantis a good beginner pet?
Yes, and it earns that recommendation honestly. Here is why experienced keepers keep recommending it:
Size and visibility. A 4-inch adult female is substantial. You can watch her strike prey, track her eyes as they move, and see the deimatic threat display up close. Small species like orchid mantises are beautiful but harder to observe day-to-day.
Temperature tolerance. The 75-85°F range is achievable with a single low-wattage bulb or even just a warm room. You do not need elaborate heating setups.
Humidity tolerance. 50-65% is the target. That is much drier than tropical species and more in line with what naturally occurs in most homes. A beginner who mists a little too much or a little too little will not kill an African mantis the way they might kill an orchid mantis.
Feeder flexibility. Sphodromantis viridis eats almost anything appropriately sized. Crickets, roaches, flies, mealworms as occasional treats — this species is not picky, which keeps feeding simple.
Temperament. African mantises are unusually interactive. They are known for tracking their keeper’s movements by rotating their heads 180 degrees from across the room. This kind of observable behavior makes them engaging pets in a way that surprises people new to mantis keeping.
The one honest caveat: juvenile African mantises (L1-L4) are still delicate, as all mantis nymphs are. If you want a species where the juveniles are even more forgiving than average, the Chinese mantis is a close alternative that handles cool temperatures particularly well.
Featured snippet: African mantis care at a glance
The African mantis (Sphodromantis viridis) needs 75-85°F and 50-65% humidity, fed live insects every other day. Early instars eat fruit flies; adults take crickets and roaches. This is the top beginner mantis recommendation: large, calm, interactive, and forgiving of care wobbles. House one mantis per enclosure.

Enclosure setup
Size and dimensions
Use the standard mantis rule: at least 3x the mantis body length in height, and 2x the body length in width. Height is critical because mantises need to hang vertically during molts — if the enclosure is too short, the mantis cannot hang freely and the molt can fail.
For L1-L4 nymphs, start with a 32 oz deli cup. Punch or drill ventilation holes in the sides (not just the lid) for cross-ventilation. Add mesh or paper towel to the ceiling so the nymph can grip.
From L5 through adulthood, a 12” x 12” x 16” or 12” x 12” x 18” tall mesh enclosure works well for adult females. Adult males are smaller and can live comfortably in slightly smaller enclosures.
Mesh enclosures are preferred because they offer airflow on all sides and a natural grip surface for molting. If you use a glass terrarium, make sure the lid is mesh (not glass) and that there are ventilation paths on multiple sides.
Temperature
The target range is 75-85°F. A basking zone of 85°F in one area of the enclosure, with an ambient of 75-78°F in the rest, is ideal. The mantis will thermoregulate by moving between zones.
The easiest way to achieve this is a 25-40W incandescent bulb positioned above one side of the enclosure. Measure with a thermometer (not just feel) before placing an animal in the setup. The mantis should be able to get within 4-6 inches of the bulb without the surface it is on exceeding 90°F.
Nighttime temperatures can drop to 65-68°F without causing problems. Temperatures below 60°F for more than a few hours are a real risk and should be avoided.
African mantises from West Africa are adapted to warm, seasonal climates. They are more cold-sensitive than Chinese mantises but more cold-tolerant than Southeast Asian tropical species like the orchid mantis.
Humidity
Target 50-65%. Mist one side of the enclosure daily, let it dry before the next misting, and you will stay in range.
In practice: give one wall a brief misting each morning. By afternoon it should be mostly dry. If it is still visibly wet by evening, reduce the amount you are misting. If the enclosure feels dry and the walls show no moisture at all, add a second light misting in the evening.
African mantises at this humidity range tolerate normal home variation well. If your home humidity ranges from 45-70% seasonally, the mantis will be fine without a separate humidifier.
The only scenario where humidity becomes critical is in the 48 hours before a molt. Keep the enclosure at the higher end of the range (60-65%) as a molt approaches to prevent stuck sheds.
Substrate and decor
Coconut coir, peat moss, or chemical-free topsoil at 1-2 inch depth. The substrate holds a small amount of moisture to stabilize humidity and makes cleanup straightforward.
Add at least one vertical branch, bamboo stick, or cork tube. African mantises are perch-sitters — they spend most of their time on a vertical surface watching downward for prey. A simple setup with a single large branch and a small piece of cork bark is all you need.
Live plants are optional but appreciated. Pothos and small tropical houseplants that tolerate moderate humidity work well. If you add live plants, choose ones that have not been treated with pesticides and rinse them thoroughly before placing them in the enclosure.
Feeding by instar
Sphodromantis viridis is one of the least picky mantis species when it comes to feeders. As long as the prey is the right size and alive, the mantis will likely strike. The general rule: prey size should not exceed 1/3 to 1/2 the mantis body length.
L1-L3 (weeks 1-6)
Drosophila hydei fruit flies are the staple at this stage. D. melanogaster (smaller fruit flies) work for L1 if hydei feels too large. Start a fruit fly culture before your nymph arrives — you will go through several jars in the first two months.
Release 5-8 flies per feeding. Check consumption after 2-3 hours and remove uneaten flies. Feed every other day.
L1-L3 nymphs are small and easily stressed by prey items that are too large or too numerous. Err on the side of fewer flies rather than more.
L4-L5 (weeks 6-12)
Transition to larger flies: houseflies, blue bottle flies, or small waxworms. Crickets become viable by late L4 if they are small enough (no larger than 1/3 the mantis body length). African mantises often take crickets more readily at this stage than some other species.
The mantis is now large enough to handle prey confidently and small enough that most keeper errors at feeding time are low-stakes. This is a comfortable stage.
L6 to adult (weeks 12+)
Adult African mantises eat enthusiastically. Crickets, Dubia roaches, houseflies, blue bottle flies, and large waxmoths are all good. Adults readily accept prey from tweezers, which allows for controlled feeding without live prey escaping in the enclosure.
A large adult female may eat every day when gravid (pregnant). A recently molted or non-breeding adult does well on feedings every 2-3 days.
Adult African mantises will occasionally attempt to take prey close to their own size. This is rarely a problem with roaches and flies, but a cricket that is too large can injure a mantis by biting back. If in doubt, go slightly smaller on prey size.
Feeding schedule summary
| Instar | Feeder | Frequency |
|---|---|---|
| L1-L2 | D. hydei or D. melanogaster fruit flies | Every other day |
| L3-L4 | D. hydei, houseflies, small waxworms | Every other day |
| L5-L6 | Houseflies, blue bottle flies, small crickets | Every other day |
| Adult | Crickets, roaches, flies, waxmoths | Every 2-3 days |
Sexing Sphodromantis viridis
Reliable sexing is possible from L4 onward using the abdominal segment method.
Turn the mantis gently so you can see the underside of the abdomen, or place it on clear plastic and look from below.
- Males: 8 visible ventral abdominal segments
- Females: 6 visible ventral abdominal segments
By adulthood the difference is visually obvious without counting:
- Adult females: 3.5-4 inches, robust abdomen, shorter wings relative to body length
- Adult males: 2.5-3 inches, slimmer, fully winged
Male African mantises develop slightly faster than females and will mature 3-6 weeks before females of the same hatch. If you plan to breed, account for this when timing purchases or hatch batches.
Deimatic display: the threat posture
One of the most striking things about Sphodromantis viridis is its deimatic (threat) display. When the mantis feels threatened, it raises its forelegs and spreads its wings to expose a bright orange or yellow coloration on the inner wing surface. The mantis simultaneously sways side to side and may open its mandibles.
This display is visually startling — entirely by design. It is meant to startle predators. For keepers, it is a fascinating behavior to observe, but it is also a clear signal: the mantis is stressed and would like to be left alone.
If your mantis displays at you during handling: put it back. Do not persist. Try again in a few hours when it has settled. Regular exposure to calm handling will reduce how often an adult displays, but some individuals are more defensive than others.
Molting
African mantis females molt 8-9 times; males molt 7-8 times before adulthood. At 75-80°F, total development from L1 to adult takes 5-7 months.
Pre-molt signs:
- The mantis stops eating 3-5 days before the molt
- It becomes motionless and hangs from the ceiling of the enclosure
- The cuticle may look slightly dull or whitish
During the molt:
Do not disturb. Do not mist. Remove all live feeders. A mantis that drops during a molt risks limb loss or death. Even a well-timed bump to the enclosure can disrupt a mid-molt. Walk away and check back in 30-60 minutes.
After the molt:
Wait 72 hours before offering food. The new exoskeleton needs time to harden. Offering prey too soon means the mantis cannot grip or bite effectively, and the prey can harm a soft-bodied post-molt mantis.
For detailed molt troubleshooting — including stuck molts, partial molts, and deformed legs — see our mantis molting guide.
Handling
African mantises are among the most handleable mantis species. Adults are large enough to feel substantial in your hand, and they are curious rather than defensive once they are used to you.
Practical handling tips:
- Wash your hands before handling. Residue from food, soap scents, or insect repellent can agitate the mantis.
- Work low: sit on the floor or hold the mantis over a bed or couch. A fall from a low height is survivable; a fall from waist height onto a hard floor is not.
- Let the mantis walk onto your hand, do not grab it. Open your hand, present it below the mantis, and wait.
- Keep sessions to 10-15 minutes while the mantis is young. Longer as the animal matures and you understand its behavior.
- The head-turning response is the most enjoyable part: hold the mantis at eye level and move your face slowly side to side. Most African mantises will track your movement actively.
Do not handle within 3 days of a molt in either direction. A newly molted mantis is fragile; a pre-molt mantis is stressed.
Breeding and oothecae
Adult African mantises breed readily in captivity. Feed the female heavily (daily if possible) for 3-4 weeks after her final molt before attempting a pairing. A hungry female is more likely to cannibalize the male.
Introduce the male to the female’s enclosure during the day when both are warm and active. Supervise the pairing. Mating typically takes 2-6 hours. Remove the male immediately afterward.
The female lays an ootheca (egg case) 4-8 weeks after mating. She produces a foamy mass that hardens into a tan-brown case, usually attached to a branch or the enclosure wall. A well-fed female may produce 3-5 oothecae.
Incubate oothecae at 82-85°F and 60-70% humidity. Nymphs hatch in 4-8 weeks. Have fruit fly cultures ready before the expected hatch date. For complete incubation and hatch management steps, see our praying mantis oothecae care guide.
How does the African mantis compare to other beginner species?
| African Mantis | Chinese Mantis | Orchid Mantis | |
|---|---|---|---|
| Difficulty | Beginner | Beginner | Intermediate |
| Temperature | 75-85°F | 68-78°F | 78-90°F |
| Humidity | 50-65% | 60-65% | 60-80% |
| Adult size | Up to 4” | Up to 4.5” | Up to 3” (female) |
| Feeder flexibility | High | High | Low (prefers flying prey) |
| Handling temperament | Excellent | Good | Limited |
| Availability | Good | Very good | Good (but expensive) |
The African mantis and Chinese mantis are both excellent first choices. The African mantis is slightly warmer in its temperature requirements but has better handling temperament and produces a more interactive pet day-to-day. The Chinese mantis is more cold-tolerant, which gives it an edge if your home is cool in winter.
Common problems
Mantis not eating: Check temperature first. Below 70°F, appetite drops noticeably. If temperature is fine, check for pre-molt posture. If neither, try a different feeder or a slightly larger prey item.
Deimatic display during handling: Normal stress response. Give the mantis space, try again later. Frequent displays from the same animal during calm handling suggest it is stressed by something environmental — check temperature, humidity, and whether it is approaching a molt.
Stuck molt: Usually a humidity issue. If you see a nymph partially stuck in its old cuticle, increase humidity by misting the walls and wait. Do not try to remove the old cuticle manually. In most cases the mantis will work free if given the right conditions.
Ootheca not hatching: Check temperature and humidity. If conditions are correct and 8-10 weeks have passed, the ootheca may be infertile or from an unmated female. Infertile oothecae are common if a female is isolated. Some females lay oothecae without mating; these will not produce nymphs.
FAQ: African mantis care
Is the African mantis a good beginner pet?
Yes, it is the most commonly recommended beginner mantis. Large size, wide feeder acceptance, moderate temperature and humidity requirements, and an engaging interactive temperament all make it accessible for first-time keepers.
How big do African mantises get?
Females reach 3.5-4 inches (up to 10 cm). Males are smaller at 2.5-3 inches. This makes them one of the larger mantis species kept in captivity, which is part of what makes them so observable and satisfying as pets.
Do African mantises bite?
They can bite if mishandled, but the bite is not medically significant to a healthy adult. Their forelegs can grip firmly and the spines can scratch, but this is not an injury risk under calm handling conditions. The bigger risk with any mantis is a fall.
Can African mantises be housed together?
No. They are cannibalistic at all life stages. You may briefly house very young nymphs (L1-L2) together in a large, heavily fed enclosure, but separating them by L3 is strongly recommended. Once they are past L3, cohabitation means one mantis eats the other.
How often should I feed my African mantis?
Every other day for nymphs. Every 2-3 days for adults, increasing to daily for gravid females. African mantises have good appetites and are generally less likely to stop eating without a reason (temperature, pre-molt, dehydration) than some more sensitive species.
What is the difference between Sphodromantis viridis and Sphodromantis lineola?
S. viridis and S. lineola are closely related African mantis species with nearly identical care requirements. S. viridis (giant African mantis) is slightly larger and more commonly available in the US and European hobby. Care for both is interchangeable using this guide.
