Procryptocerus spiniperdus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Neotropical region including Brazil, Colombia, Ecuador, French Guiana, Peru, and Trinidad and Tobago. Found in arboreal habitats like bromeliads and tree cavities on Erythrina trees ^[1][4].
• Colony Type: Unconfirmed, no specific data on colony structure in available research.
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements for queens in available research.
  • Worker: 11-12 mm ^[2]
  • Colony: Unknown
  • Growth: Unknown
  • Development: Unknown, no direct measurements available. (Development timeline is unconfirmed for this species.)
• Antkeeping:
  • Temperature: Keep warm, around 24-28°C, based on their tropical distribution ^[1].
  • Humidity: Keep nest substrate consistently moist but not waterlogged, based on their habitat in humid tropical forests ^[4].
  • Diapause: No, tropical species do not require hibernation.
  • Nesting: Arboreal setup essential. Use vertical nests or cork bark setups to mimic tree cavities ^[4].
• Behavior: Workers are generally calm and non-aggressive. They are arboreal foragers, so escape prevention is important for their medium size.
• Common Issues: arboreal nature makes standard ground nests unsuitable, they need vertical setups, tropical temperature requirements mean they cannot tolerate cool conditions, humidity control is important, too dry causes desiccation, too wet promotes mold, wild-caught colonies may carry parasites or be stressed from collection

Natural History and Distribution

Procryptocerus spiniperdus is found across northern South America, with documented populations in Brazil, Colombia, Ecuador, French Guiana, Peru, and Trinidad and Tobago ^[1]. The species was originally described from Trinidad by Forel in 1899,with the queen later described by Wheeler in 1922 ^[4].

This is an exclusively arboreal species. Research in Brazilian Atlantic forest agroecosystems found them associated with twigs and bark cavities within bromeliads on Erythrina trees ^[4]. Unlike many ant species that use suspended soil or litter inside bromeliads, P. spiniperdus occupies upper plant structures, foraging in the tree canopy ^[4]. This makes them an arboreal ant that rarely descends to the ground.

Colombian records from Caquetá and Vaupés departments show they inhabit lowland tropical areas around 60-300 m elevation, consistent with their bromeliad-dwelling ecology ^[1][5].

Housing and Nest Setup

Keeping Procryptocerus spiniperdus successfully requires mimicking their natural arboreal habitat. These ants nest in tree cavities, twigs, and bromeliads, so standard horizontal ground nests are not appropriate ^[4].

The best captive setups replicate vertical tree hollows. Cork bark nests work well because they naturally provide cavity-like spaces. Alternatively, custom acrylic nests with narrow chambers scaled to their 11-12 mm worker size can work. The key is providing a vertical or angled orientation.

Because they are arboreal, the outworld should include branches or twigs for them to walk on. A naturalistic setup with cork bark as both nest and outworld often works best. Ensure proper escape prevention, while not tiny, they are agile and will find any gaps.

Humidity should be moderate to high inside the nest. Keep the nest material moist but not dripping wet.

Feeding and Diet

As a member of the tribe Attini, Procryptocerus has some relationship with fungal resources, but they are not true leaf-cutters. They are generalist foragers in their natural habitat.

In captivity, offer a varied diet: protein sources like small insects (fruit flies, crickets, mealworms) 2-3 times per week, and sugar sources like honey water or sugar water constantly. Remove uneaten prey after 24-48 hours to prevent mold. Observe your colony's preferences, some may favor certain foods over others.

Temperature and Seasonal Care

Being a tropical species from Brazil and Colombia, Procryptocerus spiniperdus requires warm temperatures year-round. Maintain the nest area at 24-28°C consistently ^[1]. Temperatures below 22°C for extended periods can stress the colony.

A small heating cable or mat on one side of the nest can help maintain warmth, but ensure a temperature gradient so workers can move between areas. Room temperature may be sufficient in warm homes, but monitor with a thermometer.

No diapause or hibernation is required, this is a tropical ant that remains active year-round. Avoid placing the nest near air conditioning vents or drafty windows.

Behavior and Colony Dynamics

Procryptocerus spiniperdus is generally a calm, non-aggressive species. Workers are moderately active and forage both within the nest and in the outworld. Their arboreal nature means they are comfortable on vertical surfaces.

The colony structure is unconfirmed, but based on typical Procryptocerus patterns, it may be monogyne (single queen). Queens are probably slightly larger than workers, but exact measurements are not available.

Colony growth is expected to be moderate. Expect the first year to focus on establishing the colony, with growth becoming more noticeable in subsequent years.
