Metathorax meaning

The number of spiracles is greatly reduced; in the adult a pair is present on the mesothorax, sometimes also a pair on the metathorax, and there is always a pair on the first and another pair on the eighth abdominal segment.

On account of the great extension of the metathorax and the haunches of the large hindlegs, the first abdominal sternite is wanting, and the second is - the stylets.

The males are very small, free-flying insects with the prothorax, mesothorax and elytra greatly reduced, the latter appearing as little, twisted strips, while the metathorax is relatively large, with its wings broad and capable of longitudinal folding.

Two pairs of wings are present in the vast majority of insects, borne respectively on the mesothorax and metathorax.

Metathorax: m, Scutum.
