Identification
Laphria saffrana can be distinguished from other eastern North Laphria by its coloration. It has been observed with a yellowish or saffron-colored pattern, consistent with its species epithet. As with other Laphria species, it likely exhibits dense pilosity (hairiness) and a body form that contributes to its -like appearance. are thick (not thin at the ), distinguishing the from the superficially similar Mallophora.
