Introduction

Temnothorax melnikovi is a small ant species from the Palaearctic region, found in Georgia and parts of Russia. Workers are tiny, typically 2–4 mm, with a slender build and long legs. The species was first described as Leptothorax melnikovi by Ruzsky in 1905,then moved to Temnothorax by Bolton in 2003 . Their coloration is usually dark brown to black. They nest in dead wood inside oak forests .

Quick Summary

  • Difficulty: Easy
  • Origin & Habitat: This ant lives in the Palaearctic region, with records from Georgia (Akhaltsikhe and Sapara) and the Russian Federation [2]. It prefers oak forests where it nests in dead wood [1].
  • Colony Type: Colony structure is unconfirmed for this species. Most Temnothorax are monogyne (single queen), but some can have multiple queens. Ergatoid (wingless) replacement queens appear in related species, but have not been studied in T. melnikovi.
  • Size & Growth:
    • Queen: Size data unavailable, inferred from Temnothorax genus (typically 4–7 mm) [1]
    • Worker: Inferred from genus – workers are usually 2–4 mm [1]
    • Colony: Up to several hundred workers (inferred from typical Temnothorax colonies)
    • Growth: Moderate – based on related species
    • Development: Estimated 6–10 weeks based on Temnothorax patterns [1] (Temperature greatly affects speed – warmer conditions speed it up, cooler slows it down.)
  • Antkeeping:
    • Temperature: Keep at room temperature (18–24°C). Their oak forest habitat suggests they can handle a range. A gradient of 20–24°C is good for brood [1].
    • Humidity: Moderate humidity suits them. In oak forests the nest is likely damp but not wet. Keep the substrate slightly moist with some dry areas [1].
    • Diapause: Likely needed – most temperate Temnothorax have a winter dormancy. Provide 2–3 months at 5–10°C [1].
    • Nesting: Small nests that copy dead wood work best. Use Y-tong (AAC), plaster, or soil nests with tight chambers. Test tubes are fine for founding. Avoid large open spaces – these ants feel crowded in them.
  • Behavior: Temnothorax melnikovi is peaceful and not aggressive (inferred from related species). Their tiny size makes them expert escape artists – you need fine mesh (
  • Common Issues: escape risk – their small size lets them slip through gaps that seem tiny, use fine mesh and tight lids, may need a winter dormancy – without a cool rest period colonies might weaken or die, colonies grow slowly, which can test patience, unstudied biology – many care details are based on the genus, not the species itself

Housing and Nest Preferences

In nature, Temnothorax melnikovi nests in dead wood inside oak forests [1]. You can recreate this with small Y-tong, plaster, or soil nests that have narrow chambers. Test tubes work well for young colonies. The key is snug spaces – large chambers stress them. Outworlds should have fine mesh on ventilation because these ants can squeeze through very small gaps. Never use acrylic nests, they don’t hold humidity well and are hard to heat.

Feeding and Diet

Like most Temnothorax, this ant likely eats small insects, honeydew, and nectar. Offer fruit flies, pinhead crickets, small mealworms, or other tiny prey. Give sugar water or diluted honey a few times a week. Remove leftovers to stop mold. Portion size matters – prey should be no bigger than the ants themselves. They also accept small pieces of fruit or commercial ant food. [1]

Temperature and Seasonal Care

Room temperature (18–24°C) is fine. Their natural home in Georgia and Russia has seasons, so they likely need a winter rest. Gradually cool to 5–10°C for 2–3 months in autumn/winter. This rest helps health and may trigger egg‑laying in spring. Avoid sudden changes and keep the nest out of direct sun or drafts. [1]

Behavior and Temperament

Temnothorax melnikovi is calm and doesn’t bite or sting aggressively (inferred from related species). Their main challenge is escaping – use fine mesh (0.5 mm or smaller) and seal every gap. They are active foragers and will quickly explore for food. Despite being tiny, they are tough and adapt well to captivity if you keep them secure. [1]

Defense Mechanism

As a member of the tribe Crematogastrini (subfamily Myrmicinae), this species relies on a 'smear' defense. It has a flattened, spatulate stinger that wipes venom onto attackers rather than stabbing. This is general knowledge for the tribe, no specific study has been done on T. melnikovi.

Frequently Asked Questions

How long does it take for Temnothorax melnikovi to produce first workers?

Based on related Temnothorax, egg‑to‑worker takes about 6–10 weeks at 20–24°C. Cooler temperatures slow it down. This is an estimate – exact data for this species isn’t available [1].

Can I keep Temnothorax melnikovi in a test tube?

Yes. Use a small test tube with a cotton plug and water reservoir. Make sure the reservoir is long enough that ants can’t drown. For growing colonies, you can connect additional tubes [1].

Do Temnothorax melnikovi sting?

They have a stinger, but it’s very small and the venom is mild. They rarely use it on humans. Their main defense is avoiding conflict. If handled roughly, they might try to sting, but it’s painless [1].

Do Temnothorax melnikovi need hibernation?

Yes, they likely need a winter dormancy. Keep them at 5–10°C for 2–3 months in winter. This rest helps colony health and may encourage spring growth. Without it, colonies often weaken [1].

Are Temnothorax melnikovi good for beginners?

Yes, they are easy and forgiving. The main challenges are escape prevention and providing a winter rest. They tolerate a range of conditions and are peaceful. A good choice if you’re careful with sealing [1].

How big do Temnothorax melnikovi colonies get?

Colony size is unknown for this species. Related Temnothorax can reach a few hundred workers. They are not huge but can become populous over several years [1].

What do Temnothorax melnikovi eat?

Offer small live prey like fruit flies, pinhead crickets, or tiny mealworms. They also accept sugar water or diluted honey. A mix of protein and sugar keeps them healthy [1].

When should I move my colony to a formicarium?

Move when the test tube gets crowded – usually around 50–100 workers. Choose a small nest with tight chambers. Y-tong or plaster nests are better than large acrylic ones [1].

Can I keep multiple queens together?

This species’ colony type is unconfirmed. Most Temnothorax are monogyne (one queen), so keeping multiple unrelated queens together usually leads to fighting. It’s not recommended [1].

Why are my Temnothorax melnikovi escaping?

Their small size means they can go through gaps bigger than 0.5 mm. Check all connections and vents. Use fine mesh and apply fluon or oil barriers on edges. Inspect daily and seal any openings immediately [1].
