Platythyrea mocquerysi

Platythyrea mocquerysi

Platythyrea mocquerysi is a Ponerine ant species native to Madagascar, the Comoros islands, and Mayotte. These ants belong to the subfamily Ponerinae, which includes some of the more primitive ant groups known for their potent stings. Workers are relatively small and slender compared to many other Ponerines, with the genus characterized by their distinctly flattened bodies. The species was first described by Emery in 1899 from specimens collected at Antongil Bay in Madagascar ^[1].

This species shows interesting nesting preferences, while primarily associated with arboreal habitats in Madagascar's tropical forests ^[2], some collection data suggests ground-nesting behavior as well ^[3]. This flexibility likely reflects their adaptation to Madagascar's diverse microhabitats, from rainforest canopies to dry deciduous forests. The genus Platythyrea is known for some unusual colony structures, though specific details for P. mocquerysi remain unstudied.

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Madagascar, Comoros, and Mayotte. Found in tropical forests including Kirindy Forest (dry deciduous forest) and forest sites in western Madagascar ^[4][2].
• Colony Type: Colony structure is unconfirmed. Multiple queens have not been documented in this species.
• Size & Growth:
  • Queen: Unknown, not directly measured in available literature
  • Worker: Unknown, not directly measured in available literature
  • Colony: Unknown, no colony size data available
  • Growth: Unknown, development timeline not studied
  • Development: Unknown, no direct development data available. Based on typical Ponerine patterns, expect 6-10 weeks at optimal temperature. (Development timeline has not been directly studied. Ponerine ants typically have slower development than more advanced ant subfamilies.)
• Antkeeping:
  • Temperature: Keep around 24-27°C. Madagascar is tropical, so these ants prefer warm conditions. A heating cable on one side of the nest creates a suitable gradient
  • Humidity: Moderate to high humidity (60-80%). Madagascar forests experience seasonal humidity changes. Keep the nest substrate moist but allow some drying areas
  • Diapause: Unknown for this species. Madagascar has mild seasons, so a true diapause may not be required. Monitor colony activity, if they slow significantly during winter months, a brief cool period (around 18-20°C) for 2-3 months may be beneficial.
  • Nesting: Arboreal nesting preference suggests they do well in setups that retain moisture while allowing some air flow. Y-tong (AAC) nests or plaster nests work well. Provide climbing structures and bark pieces if using a naturalistic setup. Test tubes can work but monitor for mold.
• Behavior: Ponerine ants are generally more primitive and tend to be more defensive than advanced ant genera. They possess functional stingers and may use them when threatened. Workers are likely to be active foragers, hunting small invertebrates rather than collecting honeydew. Escape prevention should be moderate, while not extremely small, they are agile and may attempt to escape. They are likely nocturnal or crepuscular based on typical Ponerine behavior.
• Common Issues: Ponerine ants can be sensitive to poor husbandry, water stress kills colonies quickly, Their sting is functional and can be painful, handle with care during nest maintenance, Slow development means colonies take time to grow, beginners may lose patience, Wild-caught colonies may carry parasites that cause captive failures, Humidity control is critical, too wet causes mold, too dry causes colony death

Natural History and Distribution

Platythyrea mocquerysi is endemic to the Malagasy region, found throughout Madagascar as well as the Comoros islands and Mayotte ^[1]. The species was originally described from specimens collected at Antongil Bay on Madagascar's east coast ^[1]. More recent surveys have documented the species in western Madagascar, including the Kirindy Forest in the Melaky Region and the Beanka Reserve ^[4][2].

This species inhabits tropical forests ranging from dry deciduous forest to more humid rainforest environments. Collection data from Kirindy Forest indicates arboreal nesting habits ^[2], though some specimens have been collected from general forest sampling, suggesting they also use ground-level microhabitats ^[3]. The morphological data from specimens shows they tolerate dry conditions (dry=1 in the habitat indices) while also being found in darker forest microhabitats ^[3].

Nest Preferences and Housing

Based on collection data showing arboreal nesting habits ^[2], these ants appear to prefer elevated nesting sites. In captivity, this suggests they do well in setups that provide moisture retention while allowing some vertical space for climbing. Y-tong (acrylic) nests or plaster nests work well for Ponerine ants.

For a founding colony, a test tube setup can work initially, but monitor humidity carefully, Ponerines are sensitive to both drying out and excess condensation. When the colony reaches 15-20 workers, consider moving to a more elaborate formicarium. Provide some climbing structures like twigs or cork bark, as their arboreal habits suggest they prefer some vertical space.

Avoid completely sealed setups, some ventilation is important to prevent mold. A small gap for air flow while maintaining humidity works better than sealed containers.

Feeding and Diet

Ponerine ants are typically predators, using their sting to subdue prey. In captivity, offer small live prey such as fruit flies, small crickets, and other tiny insects. They likely hunt small invertebrates in their natural habitat, so protein-rich foods should form the bulk of their diet.

Sugar sources may be accepted occasionally, you can offer a drop of honey water or sugar water, but don't rely on it as a primary food source. Some Ponerines will accept sugary liquids, while others ignore them entirely. Observe your colony's preferences.

Feed small prey items 2-3 times per week for established colonies. Remove uneaten prey after 24 hours to prevent mold. Founding colonies will need fewer feedings, a small prey item once or twice weekly is sufficient.

Temperature and Seasonal Care

As a Madagascar species, Platythyrea mocquerysi prefers warm, stable temperatures in the range of 24-27°C. Madagascar's climate is tropical, with relatively minor seasonal temperature swings. A heating cable placed on one side of the nest can create a temperature gradient, allowing ants to regulate their own exposure to warmth.

Regarding diapause: the need for hibernation is unclear for this species. Madagascar experiences mild winters rather than cold seasons. Monitor your colony's activity levels, if they naturally slow during winter months, a brief cool period at around 18-20°C for 2-3 months may be appropriate. However, many Madagascar Ponerines do not require true hibernation and remain active year-round with proper heating.

Avoid temperature extremes, sudden drops below 20°C or spikes above 30°C can stress and kill colonies.

Behavior and Temperament

Ponerine ants are generally more defensive than advanced ant genera like Formicinae or Myrmicinae. Platythyrea mocquerysi possesses a functional stinger, and while their sting is not as potent as some larger Ponerines, it can cause discomfort. Handle nest maintenance with care, work slowly and use gentle smoke or airflow to encourage ants away before disturbing the nest.

Workers are likely active foragers, hunting individually rather than forming large foraging trails. They may be more active during evening hours based on typical Ponerine behavior. Their relatively small size means they are not aggressive toward humans unless the nest is directly threatened.

Escape prevention should be moderate. While not among the smallest ants, they are agile and will explore any gaps. Standard barrier methods (fluon on container rims, tight-fitting lids) should suffice.
