Delta pyriforme is a species of potter wasp in the subfamily Eumeninae of the family Vespidae. They are distributed across Asia. Several populations are recognized:

D. p. circinale (Fabricius, 1804)
D. p. nigrocinctum Giordani Soika, 1993
D. p. philippinense (Bequaert, 1928)
D. p. pyriforme (Fabricius, 1775)

Delta pyriforme males have a yellow labrum and clypeus contrasting with the brown body colour. They also have a yellow pronotum and differ from Delta esuriens in lacking a yellow band on the petiole. Delta conoideum lacks yellow on the thorax.^[1]^[2]
