''Sphaerularia vespae'' is a endoparasitic nematode that infects the Japanese yellow hornet, ''Vespa simillima''. It invades and resides in the gaster (abdomen) of female hornets where it grows and develops. Because ''S. vespae'' sterilizes its host, it is also known as a parasitic castrator. After ''S. bombi'', it is the second recognized species of the genus ''Sphaerularia''. == Diagnosis == ''Sphaerularia vespae'' is characterized by the round, finger-like tip tail of females and the conspicuous male bursa. These features are used to distinguish ''S. vespae'' from ''S. bombi''. In addition, the square head shape of parasitic juveniles also distinguishes ''S. vespae'' from ''S. bombi,'' which have a more round, dome-shaped head.〔
