Nomada composita Mitchell 1962

Nomada composita Mitchell, 1962: 408 (Connecticut holotype). Holotype. Female USA: Connecticut: Litchfield Co.: Colebrook (MCZ). Notes: Under-recorded due to identification difficulties, but S. Droege (pers. comm.) has recognized it from numerous sites across the region. However, material determined by him from New York and Canada proved on reexamination to pertain to two species one of which may be the morphospecies reported as Nomada sp. aff. composita Mitchell by Veit et al. (2022[“2021”]); see also Ascher et al. (2014) which differs in having an all red T 3 (lacking yellow lateral spots) and in having a wider prepygidial fimbria with yellower hairs (vs. narrower and more silvery in true N. composita) and subtle differences in spines at the apex of the hind femur. In Connecticut this species is best known from powerline ROW (Wagner et al. 2014a) where two voucher specimens confirmed to be true N. composita upon reexamination were found to vary in color, with one having small yellow sublateral spots on T 4 and some diffuse yellow on T 5 medially whereas the other had T 4- T 5 red.
