Abstract

Eighteen sexual mosaics of S. arcticum including 16 distinct gynandromorphs and 2 apparent intersexes are described. These were discovered among 41,615 normal females from Athabasca, Alberta. Male and female terminalia are compared in four specimens possessing duplicates. Four specimens including two presumed intersexes and two which appeared to be normal males were parasitized with mermithid larvae.
