The leaf insect is the extraordinary phasmid that mimics a living leaf, complete with veins, edge 'bite' marks, and a swaying gait. Its humidity sensitivity puts it just above beginner level.

Part of the Leaf insects
Leaf insects are phasmids that mimic living leaves down to vein and bite-mark detail, kept in humid mesh terrariums on fresh foodplant — beautiful but humidity-sensitive.

Habitat & space requirements
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 × 12 × 18 in (≥ 3× body length tall)
Phyllium spp. are exquisite leaf-mimics that need height (≥ 3× body length) and gentle airflow. House solitary or in same-sex small groups; cohousing males and females is fine. Mesh sides for grip during moulting.

Recommended
Planted mesh terrarium
16 × 12 × 24 in, mesh, daily mist
A larger mesh terrarium with bramble/oak/guava in water tubes, daily misting (~70% RH), warmth (~24–26 °C), and gentle airflow to prevent mould. They feed and rest among the leaves they mimic.

Ideal
Bioactive display
20 × 18 × 30 in, planted, bioactive
A bioactive planted display with live host plants, leaf litter, springtails/isopods, and stable warmth/humidity. Showcases the species' leaf-mimic camouflage at its best.
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.
Photo coming soon
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.
Photo coming soon
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 singly or in a group in a tall, well-ventilated mesh terrarium around 30-45 cm high. Maintain warmth (24-28 C) and steady humidity (60-75%) with airflow. Provide guava, bramble, oak, or rose foodplant standing in water for the insects to rest on and mimic.
Substrate
Moist coco fiber or paper towel maintains humidity and collects the seed-like eggs for incubation; keep lightly damp.
Equipment & setup
Tall ventilated mesh terrarium, foodplant water jar, spray bottle, hygrometer, and a gentle heat source to hold tropical temperatures.
Diet
A herbivore that eats bramble, guava, oak, rose, and rambutan leaves. Offer fresh, healthy foliage in a covered water jar and mist daily. Nymphs are delicate and need fresh young leaves and reliable drinking droplets to establish.
Behavior & temperament
A masterful leaf mimic — flat, green, and swaying as if in a breeze, with body edges that look nibbled. Largely sedentary and slow. Mostly parthenogenetic in culture (predominantly females). Newly hatched nymphs are reddish before greening up on foodplant.
Health
The most molt-sensitive of common phasmids; low humidity or poor leaf quality causes failed molts and nymph die-off. Keep humidity consistent with good ventilation and always offer fresh foodplant. Avoid handling delicate nymphs. Note US import/keeping regulations (USDA permit) for exotic phasmids.
Tips, DIY & hacks
Establishing nymphs is the hard part — start them on tender young leaves and keep humidity rock-steady. Incubate eggs on damp substrate; expect long hatch times. Provide leaves the insect can rest flat against to encourage natural mimicry.
