In wasps, bees and ants the 'metasoma' consists of the second abdominal segment (which typically forms a petiole) and those segments posterior to it, and is often called the gaster rather than referring to it as the "abdomen". In these insects, the first abdominal segment is called the propodeum and is fused to the thorax. The 'metasoma' is armoured with chitinous plates on the upper surface by the tergites and on the lower surface by the sternites.

Lots of anatomical words for your weekend<:))
