Looking at the length of the manica rubida, we see that the queen can reach a length of between 9 and 13 millimeters. The worker ants remain somewhat smaller, at between 6 and 9 millimeters. Buying a manica rubida means you'll be dealing with ants that hibernate sometime between December and March. They prefer to hibernate at a temperature between 5 and 12 degrees Celsius. Ideally, the ants work at a temperature between 20 and 29 degrees Celsius. The optimal temperature for this ant species is between 23 and 25 degrees Celsius. If you decide to buy a manica rubida, it's best to choose a ytong nest.
