Caring for spiny stick insects (e.g. Eurycantha calcarata) can be quite rewarding, especially for beginners or enthusiasts interested in exotic pets. Here’s a full guide on their care:
 
 
 
 
🐛 
Overview
 
 
Common Name: Spiny stick insect or Giant spiny stick insect
Scientific Name: Eurycantha calcarata
Origin: Papua New Guinea and surrounding islands
Size: Up to 15 cm (females larger than males)
Lifespan: 1 to 2 years
 
 
 
 
 
🏡 
Housing
 
 
Tank Size: Minimum 45cm x 45cm x 60cm tall for a small group. Vertical space is essential.
Ventilation: Good airflow is crucial to prevent mould.
Substrate: Soil, coconut fibre, or leaf litter kept slightly moist.
Hiding Places: Bark, cork, or hollow logs. They’re nocturnal and like shelter.
Climbing Areas: Add branches or twigs for climbing and moulting.
 
 
 
 
 
🌡️ 
Temperature & Humidity
 
 
Temperature: 22–28°C (room temp is usually fine, but avoid under 18°C)
Humidity: 60–80%
Misting: Lightly mist the enclosure once a day or every other day.
 
 
 
 
 
🥬 
Diet
 
 
Food: Bramble (blackberry), oak, hazel, rose, raspberry leaves.
Feeding Tip: Provide fresh leaves daily; use a container of water with mesh lid or soaked kitchen paper to keep cuttings fresh.
Avoid: Plants treated with pesticides.
 
 
 
 
 
🧼 
Cleaning
 
 
Remove uneaten food and droppings every few days.
Full clean every 2–4 weeks — replace substrate and wipe down the tank.

Breeding
 
 
Eggs: Females lay eggs in the substrate.
Incubation: Keep eggs warm and moist (about 6 months to hatch).
Handling: Gentle, as they are delicate — males have small spines and may “pinch” if threatened.
 
 
 
 
 
⚠️ 
Things to Watch For
 
 
Moulting Issues: Make sure there’s enough vertical space and humidity to avoid incomplete moults.
Mould: Common in overly damp tanks — ensure good airflow and don’t over-mist.
Escapees: They’re good climbers — keep the enclosure secure.
