Description
Red Spiny Devil Giant Stick Insect
The Red Spiny Devil Giant Stick Insect is an extraordinary tropical invertebrate, renowned for its impressive size, heavily armoured appearance and incredible defensive spines. Also known as the Malaysian Jungle Nymph, this spectacular species is one of the heaviest stick insects in the world and makes a fascinating addition to any specialist invertebrate collection.
Native to the tropical rainforests of Southeast Asia, particularly Malaysia, Heteropteryx dilatata is a remarkable example of natural camouflage and defence. Females develop a large, robust body covered in sharp spines, while males are considerably slimmer and possess fully developed wings.
Despite its intimidating appearance, this species is primarily a plant-eating insect, making it a fantastic display animal for keepers looking for something truly unusual.
Habitat
Red Spiny Devil Giant Stick Insects are primarily arboreal and require a spacious, well-ventilated enclosure with plenty of climbing opportunities.
-
Enclosure: A tall, secure enclosure with sufficient room for climbing, feeding and successful moulting
-
Temperature: Approximately 22–26°C
-
Humidity: Generally around 70–80%, with good ventilation
-
Lighting: A consistent day/night cycle should be provided, with normal ambient lighting generally sufficient
-
Decor: Sturdy branches, twigs and plenty of climbing structures
-
Ventilation: Good airflow is essential to prevent stagnant conditions and excessive moisture
-
Water: Regular light misting helps maintain humidity and provides drinking droplets
-
Moulting: Plenty of unobstructed vertical space is essential, particularly for growing nymphs
Due to their impressive adult size and weight, strong climbing structures are particularly important.
Feeding
Red Spiny Devil Giant Stick Insects are herbivorous and feed on a variety of suitable fresh leaves.
-
Primary Diet: Bramble and blackberry leaves
-
Alternative Foods: Raspberry, rose and other suitable pesticide-free foliage
-
Feeding Frequency: Fresh foliage should be available at all times
-
Food Preparation: Leaves must be free from pesticides, herbicides and other chemical treatments
-
Water: Drinking droplets should be available through appropriate misting
-
Maintenance: Replace old or wilted foliage regularly to maintain freshness
Fresh branches can be placed in a secure water container, ensuring the opening is covered to prevent insects from falling into the water.
General Care
Red Spiny Devil Giant Stick Insects are fascinating display animals, although their size and defensive behaviour mean they are better suited to keepers who appreciate observing rather than regularly handling their invertebrates.
-
Temperament: Generally slow-moving but capable of strong defensive reactions when threatened
-
Handling: Handling should be kept to a minimum due to their sharp spines and powerful defensive movements
-
Defence: Females can raise their spiny hind legs and clamp them together when disturbed, potentially causing injury
-
Adult Size: Females can reach approximately 14–17cm, while males are generally smaller and slimmer
-
Lifespan: Commonly around 12–24 months, depending on sex and environmental conditions
-
Activity: Primarily nocturnal, spending much of the daytime resting amongst vegetation
-
Housing: Can sometimes be maintained in suitable groups with sufficient space and food
-
Maintenance: Stable humidity, fresh foliage, good ventilation and regular enclosure cleaning are essential
Females are particularly impressive due to their heavily built bodies and prominent defensive spines, while adult males are more slender and capable of flight.
