Box-headed Blood-bee - Sphecodes monilicornis

    Description

    One of three medium-sized to large Sphecodes (Blood-bees), in which females have punctures (rather than just rugosity) behind the ocelli.  Males are one of a number of species with somewhat compressed and shiny antennal flagellar segments and are best confirmed using genitalia.

    Similar Species

    S. monilicornis is easily separated from the other two (S. gibbus and S. reticulatus) by the box-shaped head when seen in top view, with the hind corners well formed. The hairs of the hind tibiae are also whitish rather than dark like the other two, and the pygidium is broader.
