Leptothorax acervorum

Leptothorax acervorum is a miniature woodland species that lives in small spaces: dead twigs, under bark, under stones, and in peat or litter. It fills a similar niche in the hobby to Temnothorax, but with a cooler woodland feel and very small colonies that never need a large nest.

Keeping notes

Keep the setup deliberately small. A test tube, tiny acrylic nest, or twig-style chamber is far more appropriate than a standard formicarium. Feeding is minimal: tiny sugar drops and very small insect prey are enough for a colony of this scale.

Colonies may have one or more queens, and growth is slow. That makes the species excellent for patient keepers with limited space, but it is not the right choice if you want a busy outworld full of visible workers.

Watch for

• Escape scale — gaps that look sealed for Lasius may be open doors for Leptothorax.
• Tiny workers are easy to miss; inspect with good light and avoid messy substrates.
• Slow growth is normal, not a sign that you need to feed or heat aggressively.
