Crematogaster osakensis
A small amber-coloured acrobat ant. Polygynous; on autumn evenings huge numbers of alates gather at lights and dealated queens cluster in clumps.
Crematogaster osakensis is a small acrobat ant found from Sapporo in Hokkaido through Honshu, Shikoku, Kyushu, Tsushima, Yakushima, Tanegashima and Amami-Oshima, and abroad in China and the Korean Peninsula. Workers measure 2-3mm and queens about 5mm; the body is yellow to amber. Its habit of raising the gaster over the back gives it the Japanese name. It nests under stones, in soil and in decayed parts of standing trees in grassland and forest, and colonies are polygynous. Alates fly on evenings in September-October and gather at lights, after which large numbers of dealated queens cluster in sheltered spots, a familiar autumn sight. Because so many queens can be obtained then, colonies are easily founded with several queens. It favours sweets in spring and summer and readily takes sugar water or insect jelly in captivity. Common even in cities and tolerant of temperature swings and fasting, it is listed among species suitable for first-time keepers.

Keep at 23-25C, never above 30C. Honshu stock overwinters indoors unheated. Being tiny it dries out easily, so keep the test tube watered.
Alates fly on autumn evenings in September-October and come to lights. Being polygynous, several dealated queens placed together in a test tube will co-found a colony.
New queens collected at the same site can be housed together, but workers from other colonies or other species cannot be mixed in.
Small and space-saving, but with multiple queens the colony grows quickly, so expand the nest and foraging area early.
At 2-3mm it escapes easily; a sealed container and escape barrier are essential. Soak liquid food into cotton to prevent drowning.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Yellow Acrobat Ant is 23〜25℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Yellow Acrobat Ant is Queens 3-6 years. With proper care and nutrition, they can live a long and healthy life.
Yellow Acrobat Ant typically reaches Workers 2-3mm, queens about 5mm as an adult. Size may vary depending on care conditions and individual genetics.
Yellow Acrobat Ant feeds on: Mainly sugars (honeydew, sugar water); also insects. Aim for a balanced diet with appropriate feeding frequency.
