Red ant

Myrmica ruginodis

Intermediate 1,200–2,500 workers with 10–20 queens
Temperature 20–24 °C
Humidity 60–80 %
Hibernation October – March

Where it comes from

Range
Northern Palaearctic, from western Europe to Japan, in woodland and moorland
Size
Workers 4–6 mm, queen 5–7 mm
Queens
Strongly polygynous — ten or twenty queens is ordinary

Keeping them

Diet
Insects, some sugar water
Founding
Semi-claustral — the queen forages and must be fed while founding
Brood development
Egg to worker in roughly 8–10 weeks at 22 °C; late brood overwinters as larvae
Nest
Damp and cool, under bark or moss for preference
Wintering
5–10 °C

The cooler, damper cousin of Myrmica rubra, at home high up and far north. Larvae that do not finish before winter simply stop and resume in spring, so a quiet nest in autumn is not a problem.
