Aphaenogaster smythiesii - "Smyth's Funnel Ant"
Aphaenogaster smythiesii is a fascinating ant species known for its slender, elongated body and fast movements. Workers of this species are monomorphic, meaning all workers in a nest are roughly the same size, typically over 3.4mm long. They have distinguishing features like 12-segmented antennae with a 4-segmented club, which helps differentiate them from similar-looking genera such as Pheidole or Carebara. These ants are omnivorous, foraging both solitarily and cooperatively, often found in leaf litter and subterranean environments.

- Colony Type: Monogyne, claustral founding.
- Size & Growth:
- Queen: Not specified

- Colony: Small (hundreds). Slow initially, gradually increasing. growth.
- Antkeeping:
- Temperature: Maintain a temperature range of 21-24°C in the nest area, with an arena temperature of 18-28°C. A temperature gradient is beneficial, allowing the ants to choose their preferred spot..
- Humidity: The nest part should have a humidity of 50-70%, while the arena can be kept at 30-50%..
- Diapause: Required. 3-3 months at 15-15°C.
- Nesting: They prefer nesting in soil, under stones, or in rotting wood in the wild. For captive setups, a Ytong nest, acrylic nest, or a naturalistic setup with sand-loam substrate in the farm area is suitable..
- Behavior: Low aggressiveness.
- Common Issues: Queen stress from light exposure, Humidity fluctuations, Colony stalling if conditions are not optimal.
Aphaenogaster smythiesii workers are quite active and agile, making them engaging to observe in an outworld. They are known for their speed and slender appearance. Despite their active nature, they can be quite sensitive to light, often scurrying to a darker spot when exposed. Providing them with a consistently dark nest setup is crucial to reduce stress and encourage natural behavior, especially for the queen and brood.
These ants are omnivores, readily accepting a varied diet of insects and sugary foods. While they are known to forage on dead insects and collect nectar in the wild, some Aphaenogaster species also benefit from plant elaiosomes, especially when insect prey is scarce. Ensure a consistent supply of both protein (like freshly killed insects) and carbohydrates (such as honey water or sugar water).
Colony growth can be slow in the initial stages, but once established and past the first few dozen workers, their growth rate can pick up significantly, particularly when kept at optimal temperatures. Be patient with new colonies; a stable environment and consistent feeding will help them thrive and expand. Providing a suitable heating gradient allows them to regulate their own temperature, which is beneficial for brood development.
Aphaenogaster smythiesii are not considered aggressive towards handlers, but like many ant species, they may bite if their nest is disturbed. Always exercise caution when performing maintenance or observations. Their preference for nesting in soil, under stones, or in rotting logs means a naturalistic setup in your formicarium can greatly benefit their well-being and encourage natural behaviors.
While generally easy to care for once established, some Aphaenogaster species are considered semi-claustral during founding, meaning the queen may need to forage for food to raise her first workers. This differs from fully claustral queens who can sustain themselves until the first workers emerge. If acquiring a founding queen, be prepared to offer small amounts of food in a connected outworld.
Frequently Asked Questions
What kind of enclosure is best for Aphaenogaster smythiesii colonies?
For Aphaenogaster smythiesii, a setup that mimics their natural nesting preferences is ideal. Ytong nests, acrylic nests, or naturalistic setups with a sand-loam substrate are all excellent choices. Ensure there's enough space for growth, as established colonies can reach a decent size, and remember they appreciate a dark nest area.
Do Aphaenogaster smythiesii queens require feeding during founding?
Yes, some Aphaenogaster species, including potentially A. smythiesii, are considered semi-claustral. This means the queen may need to forage for food to support herself and her first brood. Providing a small outworld connected to her test tube setup with access to protein and sugar water is recommended.
What should I feed my Aphaenogaster smythiesii ants?
These ants are omnivores. Offer a varied diet of fresh-killed insects (like crickets, mealworms, or fruit flies) for protein, and sugar water or honey water for carbohydrates. They might also take small amounts of oily seeds occasionally.
Are Aphaenogaster smythiesii workers monomorphic or polymorphic?
Aphaenogaster smythiesii workers are monomorphic, meaning all workers in the colony are approximately the same size. You won't see distinct 'major' or 'minor' worker castes like in some other ant species.
Do Aphaenogaster smythiesii need to hibernate?
Yes, Aphaenogaster smythiesii requires a diapause (hibernation) period. This typically lasts for about 3 months, at a temperature of around 15°C, from late November to late February.
How fast do Aphaenogaster smythiesii colonies grow?
Colony growth for Aphaenogaster smythiesii can be slow at the beginning, especially during the founding stage. However, once a colony surpasses around 20 workers and is kept in optimal conditions (like consistent warmth), their growth rate tends to accelerate, producing more brood and workers.
Are Aphaenogaster smythiesii aggressive?
Towards handlers, Aphaenogaster smythiesii are generally considered to have low aggressiveness. However, they may bite if their nest is disturbed. They are typically agile and prefer to flee when threatened.
What kind of humidity do these ants prefer?
Aphaenogaster smythiesii prefer a relatively moist environment. Aim for 50-70% humidity in the nest area and 30-50% in the foraging arena. This helps in brood development and overall colony health.
What's the ideal temperature range for Aphaenogaster smythiesii?
For optimal health and brood development, maintain the nest area between 21-24°C. The foraging arena can be a bit cooler, ranging from 18-28°C. Providing a temperature gradient in your setup is beneficial.
Where are Aphaenogaster smythiesii naturally found?
Aphaenogaster smythiesii are native to parts of Asia, including India, China, Afghanistan, Pakistan, Nepal, and Japan. They inhabit forested ecosystems, often nesting under stones or in rotting logs.
Why are my Aphaenogaster smythiesii hiding when I observe them?
These ants are quite sensitive to light. If you expose their nest to bright light, they will quickly try to move their brood and themselves to a darker, safer location. It's best to keep their nest dark most of the time to minimize stress.
Can I keep multiple Aphaenogaster smythiesii queens together?
Aphaenogaster smythiesii colonies are typically monogyne, meaning they have a single queen. Keeping multiple queens together is not recommended, as they may not tolerate each other and could fight.
What size do Aphaenogaster smythiesii workers get?
Aphaenogaster smythiesii workers are generally over 3.4mm in length. They are considered medium-sized ants with a notably slender and agile appearance.
