Crematogaster limata

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Wet forests from Mexico to Bolivia and southern Brazil, most abundant in disturbed areas from sea level to 1000m elevation ^[2][10]
• Colony Type: Flexible – either monogyne (single queen) or polygynous (multiple queens). One wild colony contained 21 physogastric queens. Colonies are polydomous, spreading across multiple nest sites over a cubic meter or more ^[2].
• Size & Growth:
  • Queen: Size not documented, likely larger than workers, estimated ~6-7mm based on Crematogaster genus.
  • Worker: 2.7mm ^[1]
  • Colony: Up to large polydomous colonies covering 30m or more in the wild ^[4]
  • Growth: Moderate
  • Development: 4-8 weeks (estimated, no direct data for this species) (Timeline based on tropical Myrmicinae, temperature affects development speed.)
• Antkeeping:
  • Temperature: 24-28°C (based on tropical habitat ^[2])
  • Humidity: High – keep nest substrate consistently moist but not waterlogged. They inhabit wet forests ^[2].
  • Diapause: No – as a tropical species, they do not require hibernation ^[10]
  • Nesting: Test tubes for founding. For mature colonies, use Y-tong (AAC), plaster, or 3D-printed nests with narrow chambers. Provide multiple connected chambers to match their polydomous tendency. In the wild they nest in dead sticks, small twigs (1.2-1.4 cm diameter), and other cavities ^[2][6].
• Behavior: Workers are aggressive defenders of food resources – when threatened they raise their heart-shaped gaster and may exude venom droplets ^[4]. They recruit strongly to protein baits and can dominate food sources ^[2][5]. Forage day and night. Good climbers – use fluon or barrier gel on smooth surfaces to prevent escape. Polydomous colonies can spread across multiple chambers, ensure all connections are secure ^[2].
• Common Issues: small workers (2.7mm) mean high escape risk – seal all connections and use barrier on smooth surfaces., humidity requirements can cause mold if ventilation is insufficient., aggressive recruitment can stress or outcompete other species in mixed setups., queen founding type is unconfirmed – starting from a single queen may require patience and suitable conditions., polydomous colonies may need frequent expansion of nest space as they grow.

Housing and Nest Setup

Crematogaster limata is a cavity‑nesting species. In the wild, they nest in dead sticks, small twigs (1.2–1.4 cm diameter), plant stems, and abandoned insect nests ^[2][6]. In captivity, start founding colonies in test tubes. As the colony grows, move them to Y‑tong, plaster, or 3D‑printed formicaria with narrow, secure chambers. Because they form polydomous colonies, connect several chambers with tubing to allow expansion. Workers are small (2.7 mm), so ensure all passages are tight enough to provide security. Provide a moist nest substrate (e.g., soil or sand kept damp but not waterlogged) and use a water tube to maintain humidity.

Feeding and Diet

These ants are omnivorous and opportunistic. They forage day and night, recruit strongly to protein baits, and frequently tend Homoptera (aphids, scale insects) and extrafloral nectaries for honeydew ^[2]. In captivity, offer sugar water or honey as a constant carbohydrate source. Provide small insects (crickets, mealworms, fruit flies) 2–3 times per week for protein. They are aggressive recruiters – expect dozens of workers to arrive at a new food source within minutes. Remove uneaten protein after 24 h to avoid mold. Their recruitment speed has been measured at 5.5 ant·seconds⁻¹ ^[1].

Temperature and Humidity

As a tropical species from Central and South American wet forests, Crematogaster limata needs warm, humid conditions. Keep the nest at 24–28 °C, room temperature often works, but a heating cable may be needed on cooler days. Brief temperature drops are tolerated, but steady warmth is best. Humidity should be high – the substrate should feel damp to the touch. Use a water tube connected to the nest and mist the outworld occasionally, but ensure good ventilation to prevent mold growth. This species does not require diapause or hibernation ^[2][10].

Colony Structure and Growth

One of the most interesting traits of Crematogaster limata is its flexible social structure. Colonies can be monogynous (single queen) or polygynous (multiple queens). A single wild nest was found with 21 physogastric queens ^[2]. They are also polydomous – the colony spreads across many connected cavities, with a central nest containing the queen and brood and peripheral nests containing only workers. In captivity, you may need to add chambers as the colony expands. The first workers (nanitics) appear after about 4–8 weeks (estimated), then steady growth follows. Large colonies can become impressive, covering several interconnected chambers ^[2][4].

Behavior and Defense

When threatened, Crematogaster limata workers raise their heart‑shaped gaster and may exude a droplet of venom as a repellent – this is why they are called acrobat ants ^[4]. They are aggressive defenders of food resources and often dominate baits in the wild ^[4][5]. Workers forage both day and night and recruit heavily to discovered food ^[2]. They have fascinating interspecific interactions: they conduct periodic ‘raids’ on nests of the larger ant Ectatomma tuberculatum, climbing onto the Ectatomma workers and licking honeydew from their bodies, which is tolerated ^[2][9]. They also live in parabiotic associations with Camponotus femoratus, sharing nests and trails while using different food resources ^[7][8]. In captivity, they are generally calm when the nest is undisturbed, but they will defend their colony against perceived threats.

Unique Ecological Associations

Crematogaster limata stands out for its rich web of ecological interactions. It nests in parabiosis with Camponotus femoratus in ant gardens, sharing the same nest structure and trail system ^[7][8]. Ant gardens are still debated – Orivel & Leroy (2011) note that this species likely does not form true ant gardens, it is often confused with Crematogaster carinata and Crematogaster levior ^[11]. Additionally, they have a cleptobiotic relationship with Ectatomma tuberculatum, stealing honeydew directly from the larger ants ^[9][2]. Many C. limata nests contain abundant inquiline beetles of the genus Gnostus (Ptinidae) ^[2]. The syrphid fly Pseudomicrodon biluminiferus has also been found as a predator of their brood ^[12]. These associations make C. limata particularly interesting for observing complex ant interactions.
