Procryptocerus clathratus

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Native to Brazil, specifically Santa Catarina and central Amazonia. Arboreal, living in forest canopies ^[2][3][4].
• Colony Type: Colony structure is unconfirmed. No specific data on queen number or social structure.
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: Unknown
  • Growth: Unknown
  • Development: Estimated 6-10 weeks based on typical Myrmicinae patterns at warm temperatures. (No direct development data, estimates based on related species.)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on tropical habitat.
  • Humidity: Keep substrate consistently moist but not waterlogged, based on canopy habitat.
  • Diapause: Unknown, tropical species may not require diapause.
  • Nesting: Arboreal species, provide vertical nest setups such as Y-tong or naturalistic arboreal nests ^[3][4].
• Behavior: Likely docile based on genus patterns, escape risk moderate due to climbing ability.
• Common Issues: rarity in the antkeeping hobby makes finding colonies difficult, arboreal nature means standard ground nests may not be suitable, no established captive breeding protocols exist, high humidity requirements can lead to mold issues if ventilation is poor, tropical origin means they are sensitive to temperature drops

Natural History and Distribution

Procryptocerus clathratus is endemic to Brazil, with confirmed records from Santa Catarina in southern Brazil and central Amazonia. The species was originally described by Carlo Emery in 1896 ^[2]. Unlike many Myrmicinae ants that nest in the ground, P. clathratus is arboreal, they live in the forest canopy. This was confirmed when researchers collected them through canopy fogging of Calophyllum brasiliense trees in Amazonian Brazil ^[3]. The genus Procryptocerus is known for its elaborate sculptural features, with P. clathratus specifically having distinctive clathrate (lattice-like) sculpturing on the frons and promesonotum ^[1].

Identification and Morphology

Procryptocerus clathratus workers have several distinctive morphological features. The head and mesosoma display clathrate sculpture, a lattice-like pattern that gives the species its name. The frontovertexal margin is medially indistinct but laterally distinct, with a crenate outline. The vertex (top of the head) is concave, and the frontal carina is curvate. The propodeal spines are parallel and upturned. The petiole and postpetiole have areolate (network-like) sculpturing ^[1]. These features make the genus relatively easy to identify under magnification.

Housing and Nest Preferences

Being an arboreal species, Procryptocerus clathratus requires different housing than typical ground-nesting ants. In captivity, provide a vertical or elevated nest setup rather than horizontal ones. Y-tong (AAC) nests work well, or you can create a naturalistic arboreal setup with vertical structures and chambers. The nest should have narrow passages scaled to their worker size. Include a water tube for humidity and ensure the setup allows for climbing surfaces. Because they are from the Brazilian rainforest, they need high humidity, think damp but not stagnant ^[3][4].

Temperature and Humidity Requirements

As a tropical Brazilian species, Procryptocerus clathratus needs warm and humid conditions. Keep temperatures in the range of 24-28°C. A heating cable placed on one side of the nest can create a temperature gradient, allowing the ants to self-regulate. Avoid temperatures below 22°C for extended periods. Humidity should be high, aim for consistently moist substrate without flooding. In their natural canopy habitat, they experience high humidity year-round.

Feeding and Diet

Procryptocerus belongs to the tribe Attini, which includes fungus-growing ants. However, Procryptocerus itself is not a true fungus gardener. In the wild, they likely feed on small arthropods, honeydew, and possibly nectar. For captive care, offer a varied diet: protein sources like small insects (fruit flies, small crickets, mealworms), and sugar sources like honey water or sugar water. Since they are arboreal and likely foragers, they may accept small prey items.

Colony Development and Growth

No specific development data exists for Procryptocerus clathratus. Based on typical Myrmicinae patterns, expect founding to take 6-10 weeks from egg to first worker (nanitic) at optimal temperatures. Queens are likely claustral, they seal themselves in and survive on stored fat reserves while raising the first brood. Initial colony growth is typically slow, with the first few workers (nanitics) being smaller than normal workers. Once the colony establishes, growth rate should increase.
