Genus Chalybion Dahlbom, 1843 View in CoL

Chalybion View in CoL has the most complex and differentiated cocoon among genera of Sceliphrinae View in CoL , apparently due to the retention of ancestral traits, as discussed below. Rau (1915) commented that cocoons of C. californicum View in CoL are similar to those of Sceliphorn, but have an additional external silken wall, which is a feature not observed in other Sceliphrinae View in CoL . Pham (2017, fig. 1d) illustrated a cocoon of Chalybion malignum (Kohl, 1906) View in CoL in which the external layer of silk is denser than observed in species of Sceliphron View in CoL . Ohl and Höhn (2011, fig. 4d) provided a photograph of a Chalibyon sulawesii Ohl, 2011 cocoon in which the meconium can be observed placed in a differentiated, somewhat cylindrical, portion of the cocoon’s basal end.
