Dieunomia heteropoda heteropoda (Say, 1824)
Scientific Name: Dieunomia heteropoda heteropoda (Say, 1824)
Common Name: Dieunomia heteropoda
Biology: Parker et al. (1986) studied and described the nesting biology and immature stages of D. heteropoda (Say). Blair (1935) indicated that their preference for nesting in sand or sandy soils likley contributes to the discontinuous populations throughour the range; this is also likely why the species is so uncommon in Canada. Wcislo and Buchmann (1995) gave a detailed account of mating behaviour and reproductive biology. Unlike most other groups of bees, male nomiine bees have secondary sexual structures; in D. heteropoda these include the modifed antenna and enlarged hind tibia, the latter used to wrap around the metasoma of the female during copulation (Wcislo and Buchmann 1995).
