Prolasius hemiflavus

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Southern Australia (Western Australia, New South Wales, Tasmania, Victoria). They nest under stones, in trees, and near the south coast ^[1].
• Colony Type: Single-queen or multi-queen structure remains unconfirmed.
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: size data unavailable
  • Growth: Unknown
  • Development: Unknown, no development data available (Development speed has not been studied.)
• Antkeeping:
  • Temperature: Unknown, start around 20-26°C and watch how the colony reacts. Keep the environment stable and adjust based on worker activity.
  • Humidity: Unknown, provide a humidity gradient. Keep the main nest chamber mostly dry with one small moist area to match their natural under-stone habitat.
  • Diapause: Unknown, southern Australian populations may need a cool period, but this is unconfirmed. Observe your colony for signs of winter dormancy.
  • Nesting: They nest under stones and in trees ^[1]. Use a Y-tong, plaster, soil, or 3D-printed nest. Start small and expand as workers appear.
• Behavior: Activity levels and temperament are undocumented. As a Formicinae ant, they likely defend themselves with formic acid spray rather than a stinger. Escape risk is high due to their small size. Use fine mesh and secure barriers.
• Common Issues: lack of scientific data makes care recommendations uncertain, monitor colony response closely, no documented feeding preferences, offer varied sugar and protein sources and adjust based on acceptance, colony founding behavior unconfirmed, unknown if the queen seals herself in or must forage, winter care requirements unknown, unclear if diapause is needed, no known diseases or parasites documented, maintain standard antkeeping hygiene

Natural Distribution and Habitat

Prolasius hemiflavus lives in southern Australia ^[1]. You will find them in Western Australia, New South Wales, Tasmania, and Victoria ^[1]. In Western Australia, they appear along the south coast and near Jarrahdale, about 60 kilometers south of Perth ^[1]. Collectors find them in pitfall traps, in trees, and under stones ^[1]. This shows they forage on the ground and in vegetation. They prefer temperate coastal and forest-edge spots.

Identification and Morphology

Workers show two clear traits: a sharp propodeal angle and one pair of upright hairs on the pronotum ^[1]. Clark described both workers and queens in 1934 ^[1]. No published measurements exist for workers or queens, so size-based ID is hard. The genus Prolasius sits in the Melophorini tribe under Formicinae.

Housing and Nesting

Field data shows they nest under stones and in trees ^[1]. Start with a test tube for founding. Move them to a Y-tong, plaster, soil, or 3D-printed nest as the colony grows. Humidity needs are unknown. Keep the nest substrate slightly moist but not waterlogged. Watch how they use the space. Small size means escape prevention matters. Use fine mesh and secure barriers.

Feeding and Diet

No specific diet studies exist. Formicine ants usually eat a mix of sugars and proteins. Offer sugar water or honey for energy. Provide small insects like fruit flies or pinhead crickets for protein. They may accept honeydew from aphids if you keep them in a setup that allows tending. Adjust offerings based on what the workers take.

Temperature and Seasonal Care

No thermal data exists for this species. Southern Australian populations likely handle cool to moderately warm conditions. Start at 20-26°C. Watch worker behavior. If they cluster in warm spots, raise the temperature slightly. If they avoid heat, lower it. Diapause needs are unknown. Southern populations may slow down in winter, but this is unconfirmed.
