the third (last) segment of the thorax from the head, abbreviated as T3.
The last segment of the 'true' thorax, which bears the third pair of legs and usually the second pair of wings, and is fused posteriorly to the propodeum (see also mesosoma). [drawing
The third thoracic segment bearing the hind legs and the hind wings.
the third thoracic segment which bears the hind legs and second pair of wings. The metathorax is variable in structure: it may be distinct from the mesothorax, it may be closely united with the mesothorax or in some species it may appear as part of the abdomen. See prothorax. View image
the second section of the insect thorax which houses the second pair of legs and the first pair of wings
The third of the three primary subdivisions of the thorax, bearing the hind pair of legs and, when present, the hind wings.
This is the last segment of the thorax. It has one pair of wings and one pair of legs.
The metathorax is the posterior of the three segments in the thorax of an insect, and bears the third pair of legs. Its principal sclerites (exoskeletal plates) are the metanotum (dorsal), the metasternum (ventral), and the metapleuron (lateral) on each side. The metathorax is the segment that bears the hindwings in most winged insects, though sometimes these may be reduced or modified, as in Diptera, in which they are reduced to form halteres, or flightless beetles (Coleoptera), in which they may be completely absent even though forewings are still present.
