Vietnamese Stick Insect
Medauroidea extradentata
The Medauroidea extradentata, the Vietnamese Stick Insect. It is, together with the C. morosus, the most famous and absolute easiest phasmid for beginners. The animal embodies the perfection of essential mimetic evolution: a long, thin and dry twig of 4 inches, brown and green in color. It is so robust that it forgives almost any temperature and humidity error typical of neophytes. Obligate parthenogenetic in captivity (almost exclusively females that auto-clone themselves by laying eggs are found), it is 100% herbivorous and loves bramble, ivy and hazel. The nymphs (L1) are incredibly skilled at escaping if the ventilation holes of the bin are not tiny.

Descrição da espécie
Geographic Origin and Habitat: The consulted Phasmida Species File record has a distribution line reading “Vietman” and a California, United States occurrence marked in the source as introduced. The spelling in that source line requires source-level confirmation before it is normalized in the dataset.
Taxonomy and Genetics: Phasmida Species File identifies Medauroidea extradentata (Brunner von Wattenwyl, 1907) as a species in subfamily Clitumninae, tribe Medaurini, genus Medauroidea.
Behaviour and Habits: The record gives its ecology as terrestrial.
Morphology and Sexual Dimorphism: The consulted taxonomic record does not provide a comparative description of the sexes.
Cuidado, criação e companheiros de tanque
Terrarium Setup: This proposal does not establish a terrarium setup. The cited research examined the arolium, euplantulae, and body surface of adult female Medauroidea extradentata; it is not a setup guide.
Lighting and Heating: The study kept its adult female specimens in a climate chamber at 24 °C with a 12 L:12D photoperiod. This is an experimental maintenance condition, not a general husbandry recommendation.
Humidity and Hydration: The study kept its adult female specimens at 70% relative humidity. This is an experimental maintenance condition, not a general husbandry recommendation.
Feeding and Supplementation: The study provided blackberry leaves ad libitum. This records the study protocol only; it does not establish a complete diet or supplementation guidance.
Compatibility and Coexistence: This proposal does not establish compatibility or cohabitation guidance.
Health and Common Diseases: The article reports differences in hydrocarbon composition between the arolium and euplantulae secretions. This is an anatomical and chemical research result, not clinical, disease, or veterinary guidance.

Perfil de invertebrados terrestres
- Dieta
- Herbivore
- The diet of Medauroidea extradentata requires careful consideration to ensure optimal health. In captivity, a varied and appropriately sized selection of food items is necessary to mimic their natural intake. Keepers must provide a balanced feeding schedule and consider nutritional supplements. Proper hydration alongside the diet is also crucial for their digestion. Understanding these dietary needs is fundamental to successful husbandry.
- Tamanho adulto
- 11 cm
- Estilo de vida/Microhabitat
- Arboreal
- The lifestyle of Medauroidea extradentata is perfectly suited to its natural habitat, dictating its physical and spatial needs. Whether they are climbers, burrowers, or ground-dwellers, their enclosure must reflect these requirements. Providing ample space and correct structural elements is necessary to accommodate their daily routines. A proper setup not only ensures physical health but also encourages natural exploration. Simulating their native lifestyle is the cornerstone of excellent husbandry.
- Ciclo de atividades
- Nocturnal
- The activity pattern of Medauroidea extradentata is closely linked to natural diurnal or nocturnal cycles. They exhibit peak periods of movement and foraging that align with their instinctual rhythms. Maintaining a consistent day-night light cycle in their enclosure is essential for their health. Disruptions to this routine can cause lethargy and affect their feeding response. A well-regulated environment ensures they remain active and healthy.
- Socialidade
- Gregarious
- This species is completely peaceful and non-cannibalistic. They can, and often are, housed communally in large numbers. As long as there is an abundance of fresh food and sufficient vertical space for all individuals to molt safely, overcrowding is the only significant concern.
- Reprodução
- Oviparous
- The reproductive processes of Medauroidea extradentata are fascinating and require specific environmental cues. Successful breeding often depends on precise temperature, humidity, and lighting adjustments. Mating behaviors can be complex, requiring careful observation to ensure the safety of the animals. Once successful, proper care for the resulting eggs or offspring is paramount. Dedicated breeders can achieve rewarding results by mimicking their natural habitat.
- Venenoso
- No
- Tolerância de tratamento
- Tolerant
- Handling Medauroidea extradentata should be approached with caution, respect, and proper technique. Unnecessary manipulation can induce stress, so it is best kept to a minimum or during essential health checks. When handling is required, slow and supportive movements are crucial to prevent injury. Ensuring a safe, calm environment during these brief periods protects both the animal and the handler. Always observe the animal's body language to gauge its comfort level.
- Brumação
- Não obrigatório
- The brumation or resting period for Medauroidea extradentata is an important biological phase tied to seasonal changes. During this time, they may exhibit a significant decrease in activity and appetite. Keepers should carefully research the specific environmental triggers needed to safely induce and end this phase. Monitoring weight and overall condition before and during brumation is vital. This resting period often plays a key role in their long-term health and reproductive success.
- Muda
- Regular
- The shedding or molting phase is a delicate time for Medauroidea extradentata that requires specific environmental conditions. Maintaining adequate humidity is essential to help them shed their old skin completely and without complications. Retained skin can lead to serious health issues if not addressed promptly by the keeper. Observing pre-molt signs, such as dull coloration or behavioral shifts, allows for timely adjustments. A successful molt is a strong indicator of good husbandry and animal health.
