Mouthparts, antennae and genitalia of intersex Culicoides stellifer parasitized by mermithid nematodes.
A 12-month study of Culicoides in Bulloch County, Georgia, U.S.A., revealed that twelve of 23,859 specimens (0.05%) of C.stellifer were intersexes as a result of being parasitized by mermithid nematodes. Of these, eleven had male genitalia and female type antennae and one had female genitalia with male type antennae.
