Orange Head Roach
Eublaberus posticus
The Eublaberus posticus (Orange Head Roach). It is a spectacular South American roach (about 1.6 inches), famous for its chromatic 'Aposematism': both nymphs and adults exhibit an extraordinary large spot (pronotum) of a bright Pumpkin Orange/Red set between raven black wings or burgundy bodies. Unlike the shy Dubia, Orange Heads are opportunistic carnivores, fierce detritivores, insatiable devourers of carcasses and excrement (bat guano in nature). They have a monstrous protein appetite (if undernourished they rapidly become cannibals devouring molting companions). They move much faster than Dubias and males are excellent flyers who love to dive from the top of perches. They require a substrate to dig in (being partly burrowers) and suffocating heat to thrive. A fantastic 'premium' feeder insect, very active and stimulating for predatory reptiles.

Profil d'invertébré terrestre
- Régime alimentaire
- Omnivore
- The diet of Eublaberus posticus 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.
- Taille adulte
- 5.2 cm
- Mode de vie/microhabitat
- Terrestrial
- The lifestyle of Eublaberus posticus 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.
- Cycle d'activité
- Nocturnal
- The activity pattern of Eublaberus posticus 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.
- Sociabilité
- Gregarious
- This is a communal species that absolutely thrives in very large, dense groups. However, their social dynamics are quite aggressive, particularly regarding food competition and access to mates. Overcrowding without a massive surplus of protein and hiding spots will almost certainly lead to visible wing biting and fatal cannibalism among the colony members.
- Reproduction
- Ovoviviparous
- The reproductive processes of Eublaberus posticus 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.
- Venimeux
- No
- Tolérance aux manipulations
- Tolerant
- Handling Eublaberus posticus 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.
- Brumation
- Non requise
- The brumation or resting period for Eublaberus posticus 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.
- Mue
- Regular
- The shedding or molting phase is a delicate time for Eublaberus posticus 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.
