Cataulacus reticulatus

Quick Summary

• Difficulty: Unknown
• Origin & Habitat: Borneo (Sarawak), Peninsular Malaysia, Indonesia (including Celebes/Sulawesi) ^[1][2]
• Colony Type: Unconfirmed, colony structure has not been documented
• Size & Growth:
  • Queen: size data unavailable, queen has not been described in literature
  • Worker: 4.2mm total length ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown
  • Development: Unknown, no development data exists for this species (Development timeline is unstudied)
• Antkeeping:
  • Temperature: Unconfirmed, likely 24-28°C based on tropical rainforest origin. Start in this range and observe colony activity.
  • Humidity: Unconfirmed, likely requires high humidity typical of arboreal rainforest ants. Keep nest substrate moist but not waterlogged.
  • Diapause: Unknown, tropical species may not require formal diapause but may show reduced activity during cooler periods
  • Nesting: Arboreal species, likely prefers nests in hollow twigs, bamboo, or nests with narrow chambers. Y-tong or plaster nests with small chambers work as captive alternatives.
• Behavior: Behavior is unconfirmed. The genus Cataulacus is generally known to be less aggressive and more docile than many Myrmicinae. Workers are relatively slow-moving. Escape prevention should be moderate, workers are small but not extremely tiny. They likely forage in the canopy layer and may tend aphids or collect honeydew.
• Common Issues: No biological data exists, keepers must experiment with care conditions, Colony may fail if temperature or humidity is incorrect since optimal ranges are unknown, Growth rate is unknown, colonies may grow very slowly or quickly depending on undiscovered requirements, Wild-caught colonies may have unknown parasites or diseases, Feeding preferences are unconfirmed, may be selective about food types

Species Identification and Taxonomy

Cataulacus reticulatus was originally described by Frederick Smith in 1857 from specimens collected in Sarawak, Borneo. The species was later considered a junior synonym of Cataulacus granulatus but was revived as a valid species by Bolton in 1974. The holotype worker measures 4.2mm in total length, with distinctive features including a complete occipital crest raised into a low ridge, preocular teeth, and well-developed propodeal spines. The body sculpture shows fine rugoreticulum with reticulate-punctate interspaces. This species is part of the taprobane group, distinguished from related species by specific morphological characters detailed in Bolton's 1974 revision ^[1].

Distribution and Habitat

Cataulacus reticulatus is known from Borneo (specifically Sarawak in East Malaysia), Peninsular Malaysia, and Indonesia. Historical records also mention Celebes (Sulawesi) and Tondano in the broader distribution ^[2]. The species appears to be restricted to the Indomalaya region. As an arboreal ant genus, Cataulacus species typically inhabit forest canopies, nesting in hollow twigs, branches, or pre-existing tree cavities. The tropical rainforest environment suggests they prefer warm, humid conditions with ample vegetation cover.

Unknown Biology - What We Don't Know

AntWiki explicitly states that nothing is known about the biology of Cataulacus reticulatus. This includes critical antkeeping information such as: colony size and structure (monogyne vs polygyne), founding behavior (claustral or semi-claustral), diet preferences, nuptial flight timing, development timeline, and overwintering requirements. Even the caste system (whether they have distinct worker subcastes) is undocumented. This makes keeping this species particularly challenging, as there are no established care guidelines to follow. Keepers will need to experiment and potentially draw inferences from related Cataulacus species, though such inferences should be treated as educated guesses rather than established requirements ^[1].

General Cataulacus Genus Information

While specific data for C. reticulatus is lacking, the Cataulacus genus as a whole provides some context. Cataulacus ants are arboreal Myrmicinae known for their distinctive appearance with spines and sculptured bodies. They typically nest in above-ground locations like hollow twigs, bamboo, or tree cavities. The genus is not particularly aggressive compared to many arboreal ants. Workers are generally moderate-sized and slow-moving. In captivity, they often accept sugar water, honey, and small insects, though exact dietary requirements vary by species. Related species in the taprobane group may share similar biology, but this remains unconfirmed for reticulatus specifically ^[1].

Recommended Care Approach

Given the complete lack of biological data for this species, keepers should approach care experimentally. Start with conditions typical of tropical arboreal ants: temperatures around 24-28°C, humidity 70-85%, and nests that mimic their natural arboreal habitat. Y-tong nests with small chambers or plaster nests work well for arboreal species. For feeding, offer a varied diet including sugar water/honey, small live insects (fruit flies, pinhead crickets), and observe what is accepted. Keep detailed notes on colony behavior and adjust conditions based on observed preferences. Given the species' rarity in the hobby and lack of documented captive success, this is an experimental species for advanced antkeepers willing to contribute to collective knowledge ^[1].
