ⓘ Propodeum

The propodeum or propodium is the first abdominal segment in Apocrita Hymenoptera. It is fused with the thorax to form the mesosoma. It is a single large sclerite, not subdivided, and bears a pair of spiracles. It is strongly constricted posteriorly to form the articulation of the petiole, and gives apocritans their distinctive shape.
