🏠 Enclosure
- Use a 30 × 30 × 45 cm ventilated enclosure for a small group, reducing numbers if animals crowd the hanging sites.
- Height must remain at least three body lengths after foliage is installed.
- Separate new stock for several weeks and inspect food intake, droppings and molts.
🪨 Enclosure furniture
- Provide upright food branches and clear space below the ceiling for molting.
- Paper on the floor makes eggs and droppings visible; a thin 1–2 cm clean substrate layer is optional.
- Inspect every branch before replacing it because tiny nymphs resemble leaf stalks.
💡 Lighting
- Provide a normal 12-hour light cycle and darkness at night.
- Special UVB is not established as necessary.
- Avoid direct sunlight through glass.
🌡️ Temperature
- Aim for 20–24°C by day and 18–21°C at night.
- A stable heated room is usually simpler than heating a small cage.
- If supplementary heat is needed, use a thermostat and leave a cooler area.
- Do not deliberately chill eggs or animals to delay development without a species-specific protocol.
💧 Humidity & water
- Maintain moderate humidity, approximately 50–70%, with ventilation.
- Lightly mist some leaves for drinking when needed, allowing them to dry between applications.
- Waterlogged paper and persistent condensation are unnecessary.
- Cover the water container holding cut branches so no nymph can fall in and drown.
🪳 Diet
Staple foods — follow the feeding schedule:
- Keep fresh, pesticide-free bramble, rose or suitable privet available continuously.
- The PSG also records ivy among accepted foodplants for this species; do not generalize that choice to other animals.
- Wash leaves, avoid sprayed gardens and roadside collecting, and replace wilted stems.
- Inspect chewing marks daily: newly hatched nymphs may need tender leaf edges.
In moderation:
- Introduce a new accepted foodplant gradually while retaining familiar fresh leaves.
Avoid:
- Pesticide-contaminated food, spoiled leftovers and unverified wild-collected foods.
Supplements:
- Reptile calcium and vitamin powders are unnecessary.
🩺 Health — warning signs
- Failed molts usually call for checking hanging clearance, crowding and drying conditions.
- Persistent food refusal with few droppings suggests unsuitable or contaminated leaves.
- Several animals becoming weak together warrants immediate investigation of pesticide exposure and a change to verified safe food.
- Do not pull off old skin; seek an invertebrate-experienced veterinarian for injury, leakage or sustained decline.
