Solenopsis belisarius

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Western Australia, restricted to the mid-north regions around Geraldton and Carnarvon, in arid to semi‑arid habitats ^[1][2].
• Colony Type: Unconfirmed, likely monogyne (single queen) based on typical Solenopsis patterns, but no specific data available.
• Size & Growth:
  • Queen: Size data unavailable
  • Worker: Size data unavailable
  • Colony: Unknown
  • Growth: Unknown
  • Development: Unknown (No published data on development times for this species.)
• Antkeeping:
  • Temperature: Temperature requirements are unconfirmed. As an arid‑adapted species, maintain moderate warmth around 20‑25 °C with a gradient if possible. Avoid extremes below 15 °C or above 35 °C.
  • Humidity: Humidity needs are unconfirmed. Given its dry natural habitat, keep the nest substrate mostly dry with a small moist area in the outworld. Avoid waterlogging.
  • Diapause: Unknown, the species comes from a warm‑temperate/arid region in Western Australia, so a strict diapause may not be necessary. A mild winter rest period (2‑3 months at 10‑15 °C) could be beneficial but has not been studied.
  • Nesting: In nature they probably nest in soil or under stones, common for Solenopsis. For captivity, test tubes or small formicaria (Y‑tong, plaster) with compact dark chambers can be tried. No validated nest design exists.
• Behavior: Behavior is poorly documented. Based on its subfamily and tribe, Solenopsis belisarius has a functional sting and is likely an aggressive forager. Workers will recruit nestmates to food sources and defend their territory. Given the unknown worker size, excellent escape prevention is recommended regardless.
• Common Issues: stinger, they can sting and the pain is noticeable, handle with care., escape prevention, even if exact size is unknown, assume they can squeeze through tiny gaps and use fluon and fine mesh., unknown husbandry, because basic requirements are unstudied, colonies are at risk from improper temperature, humidity, or disturbance., wild‑caught colonies may carry parasites that cause colony failure., overheating can be fatal, avoid temperatures above 35 °C.

Housing and Nest Setup

Housing requirements for Solenopsis belisarius are not documented. A test tube setup (water reservoir with cotton plug) is a safe start for a single queen, though her founding method is unknown. For a small colony, any standard formicarium with compact, dark chambers (Y‑tong, plaster, or 3D‑printed) can be offered. Keep the nest dry and provide a small foraging area. Escape prevention is critical, use fluon on all rims and seal connections tightly. Observe the colony often to adjust conditions.

Feeding and Diet

Based on the genus, Solenopsis belisarius is likely an omnivorous predator and scavenger. Offer small insects (fruit flies, pinhead crickets, mealworms) as protein, and sugar water or honey as carbohydrates. Feed every 2-3 days and remove uneaten prey after 24 hours to avoid mould. For a founding queen, provide a tiny drop of honey water and occasional prey if she appears active. No specific dietary studies exist for this species.

Temperature and Seasonal Care

Temperature needs are unconfirmed. The species lives in arid Western Australia, so keep the nest warm (20-25 °C) with a gradient using a heating mat. Avoid prolonged temperatures above 35 °C. A seasonal rest period may not be required, but if the colony shows reduced activity in winter, a mild dormancy of 2-3 months at 10-15 °C could be attempted. Do not feed during the coldest part. Monitor the colony’s response.

Behavior and Defense

Solenopsis belisarius belongs to the sting‑bearing subfamily Myrmicinae and tribe Solenopsidini. Workers possess a functional stinger and will use it to subdue prey and defend the nest. The venom contains piperidine alkaloids, causing a sharp, burning pain typical of fire ants. Caution is advised when handling the colony. Foraging behavior is likely similar to other Solenopsis: efficient recruitment using chemical trails, active day and night. Exact colony behavior has not been studied.

Colony Growth and Development

Colony founding and growth are unconfirmed for this species. Based on typical Solenopsis patterns, a newly mated queen may seal herself in a chamber and raise the first brood on stored reserves (claustral founding). The first workers (nanitics) would then begin foraging. Colony size probably reaches a few hundred workers, but no verified data exists. The growth rate, development time, and presence of repletes are unknown.
