You’ve decided you want a praying mantis. Good choice. But buying one is nothing like buying a hamster or a fish. There’s no PetSmart aisle for mantises, the shipping logistics are different from anything you’ve dealt with, and picking the wrong seller can mean a dead bug in a box.
This guide covers everything you need to know before you buy a praying mantis online — where to find them, what to look for in a seller, which species to pick, and what you need to have set up before it arrives at your door. (New to the hobby? It’s worth a quick check that keeping a mantis is legal where you live.)
Where to buy a praying mantis
You have three main options, and they’re not created equal.
Dedicated breeders are your best bet. A breeder who focuses on mantises knows the animals, raises them properly, and ships them routinely. They can tell you the exact instar, the hatch date, and what the nymph has been eating. They also tend to carry multiple species and can help you pick the right one for your experience level.
Pet stores occasionally carry mantises, but it’s rare and usually limited to Chinese mantises (a naturalized species) or native Carolina mantises — typically wild-caught or pet-store ootheca hatchlings. You won’t find exotic species, you won’t know the age or instar, and the staff usually can’t answer mantis-specific questions.
Online marketplaces and classified sites are hit or miss. Some legitimate breeders sell through these platforms, but you’re also dealing with resellers who bulk-ordered oothecae, hatched them in a shoebox, and have no idea what they’re doing. There’s no accountability if your mantis arrives dead.
For exotic species like Orchid Mantis, Ghost Mantis, or Spiny Flower Mantis, a specialized breeder is realistically your only option.
What to look for in a seller
Not all sellers are equal. Here’s what separates a good operation from a bad one:
Captive-bred stock. This is non-negotiable. Captive-bred mantises are healthier, parasite-free, and adapted to enclosure life. Wild-caught mantises are stressed, often carrying parasites, and have unknown histories. Any reputable seller will explicitly state their animals are captive-bred.
Live arrival guarantee. Shipping live insects involves risk — extreme temperatures, rough handling, delays. A seller who guarantees live arrival is putting their money behind their shipping practices. If they won’t guarantee it, they’re telling you they don’t trust their own process.
Transparent shipping practices. Good breeders use insulated boxes, heat packs in winter, cold packs in summer, and ship via express carriers. They’ll hold shipments during extreme weather rather than risk your animal. They should be able to tell you exactly how they pack.
Clear communication. A good seller will tell you the species, the instar, and what they’re feeding. They’ll answer your questions before you buy. If someone can’t tell you what instar a nymph is, they shouldn’t be selling it.
Reviews and reputation. Check for reviews, look at their social media, see how they handle problems. A breeder who has been at it for years and has happy customers is a breeder who knows what they’re doing.
At Lobo Mantis, we ship captive-bred mantises with a live arrival guarantee, insulated packaging, and a clear photo of what you’re getting. Every listing includes the species, current instar, and care requirements. That should be the baseline for any seller you consider.
Choosing your first species
Not every mantis is beginner-friendly. Some need exact humidity, some are fragile at small instars, some are skittish and prone to bolting when you open the enclosure. For a deeper breakdown, see our guide to the best pet mantis for beginners, and if you’re torn between the two most popular picks, the orchid mantis vs ghost mantis comparison covers the tradeoffs.
Best beginner species:
- Ghost Mantis — Hardy, tolerant of a range of conditions, slow-moving, and one of the few species that can be raised communally with enough space, clutter, and steady feeding — though even ghosts will cannibalize if crowded or underfed. This is my top recommendation for first-time keepers, and beginners are usually safest housing one mantis per enclosure. See the ghost mantis care guide for specifics.
- Spiny Flower Mantis — Bold, colorful, and aggressive eaters. They’re not shy and will take food without hesitation. They do want good ventilation and moderate humidity, and are a touch less forgiving of stale air than ghost or dead leaf.
- African Twig Mantis — Low maintenance, interesting body shape, and tolerant of room temperature conditions.
- Double Shield Mantis — Long-lived and impressive, but they’re large and need appropriately sized enclosures and feeders as adults.
Intermediate species:
- Dead Leaf Mantis — Easy care requirements and incredibly cool camouflage. Very forgiving of minor humidity fluctuations.
Expert species:
- Orchid Mantis — Stunning but more demanding. They need higher humidity, consistent temperatures, and females can be picky eaters. Not hard, but not as forgiving.
Pick something forgiving for your first. You can always move up to the more demanding species once you’ve got the basics dialed in.
What instar to buy
Mantises are sold by instar — the stage between molts. L1 is fresh out of the egg, L2 is after the first molt, and so on up through adulthood.
L1-L2 nymphs are the cheapest but also the most fragile. They need fruit flies (Drosophila melanogaster), tiny enclosures, and precise humidity. They’re easy to lose if you don’t know what you’re doing. I generally don’t recommend L1 for first-time buyers.
L3-L4 nymphs are the sweet spot for beginners. They’re past the most fragile stage, big enough to handle small prey confidently, and you still get to watch most of their growth. They’ve been established on feeders and have proven they’re eating well.
L5 and above are more expensive but nearly bulletproof. If you want maximum ease and don’t mind missing the early growth stages, this is a safe bet.
Sub-adults and adults give you the least time with the animal (most mantises live between 6 and 18 months from hatch, varying widely by species and sex) but are the easiest to care for. Good if you want to experience keeping a mantis before committing to raising one from a nymph.
What you need before your mantis arrives
Do not order a mantis and then figure out the setup when it arrives. Have everything ready and waiting. Here’s your checklist:
Enclosure. For nymphs L1-L3, a 32oz deli cup with ventilation holes works perfectly. For L4 and above, you’ll want a proper acrylic enclosure or mesh cage. Rule of thumb: the enclosure should be at least 3 times the mantis’ body length tall and 2 times wide. Check our terrarium setup guide for details.
Feeders. Have feeders on hand before your mantis arrives. Fruit flies (D. melanogaster for small nymphs, D. hydei for medium nymphs), houseflies or green bottle flies for medium-large nymphs, and blue bottle flies for sub-adults and adults. See our feeder insects guide for matching prey to instar. Your mantis will be hungry after shipping stress.
Misting bottle. A simple spray bottle for maintaining humidity. Mist the enclosure walls — never spray directly on the mantis.
Thermometer and hygrometer. Know what’s happening inside the enclosure. A combo unit that sticks inside works fine.
Substrate or paper towel. Paper towel on the bottom for easy cleaning. Some keepers use coco fiber for humidity retention, but paper towel is better for beginners because you can spot mold or mites immediately.
Something to climb on. A stick, a piece of fake plant, or mesh on the lid. Mantises need to hang upside down to molt. Without a suitable perch, they can mismolt and die.
Red flags to avoid
Walk away from any seller who:
- Can’t tell you the exact species or instar
- Ships without insulation or heat/cold packs
- Has no live arrival guarantee
- Sells wild-caught mantises as “captive bred”
- Won’t answer questions before the sale
- Has no reviews or a pattern of complaints about dead arrivals
- Ships during extreme heat (over 95F) or cold (forecast lows below ~45-50F along the route) without adding a heat pack or holding the shipment — see how we handle weather holds and live arrival
- Lists mantises at suspiciously low prices — healthy captive-bred exotics cost what they cost (here’s what a praying mantis actually costs)
