The Indian (laboratory) stick insect is the classic beginner phasmid — easy, all-female parthenogenetic colonies that breed readily on bramble or privet. Because it breeds so prolifically and could establish as a crop pest, it is USDA-regulated in the US: a federal permit is required to keep or move it, and some states prohibit it outright.

Part of the Stick & Leaf Insects
Phasmids (order Phasmatodea) kept as gentle, low-cost display insects prized for their twig- and leaf-mimicking camouflage. Most are herbivorous, non-venomous, and harmless to handle, feeding on bramble and other foliage, though many non-native species are regulated (a USDA PPQ 526 permit is required for many in the US) and must never be released outdoors.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Tall mesh enclosure
12 × 8 × 18 in (≥ 3× body length tall)
Carausius morosus is parthenogenetic — even one female produces fertile eggs, so escape-proofing matters (this species is invasive outside its range). Tall enclosure with a fine-mesh lid is non-negotiable. Cull surplus eggs responsibly.

Recommended
Larger mesh terrarium with bramble
16 × 12 × 20 in, mesh sides
A bigger mesh terrarium with bramble/oak/ivy in water tubes, daily light misting, and a leaf-litter floor. Multiple animals tolerate each other well — they are a classroom-classic for that reason.

Ideal
Planted display enclosure
24 × 18 × 30 in, planted, mesh
A tall planted display with living food plants where possible, varied climbing structure, and a leaf-litter floor with bioactive cleanup crew. Keep all openings sealed against escape.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg
Insects begin as eggs, laid singly or in clusters on or near a food source. Egg size, shape, and incubation time vary widely; some are glued to surfaces, others inserted into plant tissue or soil.

Larva / Nymph
The immature stage either looks grub- or caterpillar-like and very different from the adult (a larva, in beetles, flies, and butterflies) or like a wingless miniature adult (a nymph, in roaches, mantises, and stick insects). It eats and molts repeatedly as it grows.

Pupa
In insects with complete metamorphosis, the larva pupates — often in a cocoon, chrysalis, or sealed cell — and its body is reorganized into the adult form. Nymph-developing insects skip a true pupa and molt straight to the adult.
Adult
The adult is the sexually mature, usually winged stage with the species' full coloration and form. Adults are typically the dispersing and reproducing stage, and in many insects do not grow further once mature.
Habitat & enclosure
Keep a small group in a mesh or netted vertical enclosure at least 3x the body length tall so they can hang to molt. A 30 cm cube houses several. They are social-tolerant and live happily together. Room temperature suits them; mist lightly for humidity and drinking.
Substrate
A paper-towel or coco-fiber base catches droppings and the scattered eggs, which look like tiny seeds and can be incubated in place.
Equipment & setup
Netted/mesh tall enclosure, a vase or jar to keep cut foodplant fresh, and a spray bottle. No heating needed at room temperature.
Diet
A herbivore that eats fresh leaves — bramble (blackberry), privet, hawthorn, ivy, and oak are favorites. Stand cut stems in water (cover the opening so insects can't drown) and replace as they wilt. They drink misted droplets from leaves.
Behavior & temperament
Nocturnal, slow-moving twig mimics that sway like a branch in wind. Reproduces parthenogenetically — virtually all are female and lay fertile eggs without males. Calm and easy to handle, though they can drop and regrow legs (autotomy) when stressed.
Health
Hardy. Main risks are molting failure from insufficient height and mold from soggy enclosures — keep airflow good. Avoid wilted or pesticide-sprayed foliage. Young nymphs can regenerate lost limbs across molts. Legality is the real concern: as a potential invasive crop pest, the USDA regulates it (PPQ permit) and keeping or releasing it is prohibited in some US states.
Tips, DIY & hacks
Because it breeds so fast, freeze unwanted eggs to control numbers and never release insects or eggs outdoors. Confirm your state's rules and any required USDA permit before acquiring. Line the floor with paper towel to make collecting the seed-like eggs easy.
