The evolution of insect in size is limited because they have a rigid esoskeleton. For this reason they grow with metamorphosis.

In Cenozoic, Formicum species queen had an opening haul of 15 millimeters. Probably workers - don't know - could kill small birds. Currently, the biggest ant is Dorylus (Anomma) wilverthi queen: it's lenght is over 6 mm.

there was a time about 100 million years ago called the carboniferous age where because of the huge quantities of oxygen in the atmosphere some insects such as an ancestor of the dragonfly where around a meter long :shock: and some tarantulas were eating things the size of cats but because of oxygen levels dropping these species of giant insects died away, if this hadn't had happened then maybe insects like ants could have been very big.
