Sphecomyia weismani
Sphecomyia weismani is a hoverfly species described in 2019, one of seven new species identified during a comprehensive revision of the genus Sphecomyia. It belongs to the S. pattonii species group, distinguished from other Sphecomyia by the absence of pruinose scutellar vittae. The species is a wasp mimic, exhibiting the characteristic large size and yellow-and-black coloration typical of this Holarctic genus. Like other members of subtribe Criorhinina, it likely develops in decaying wood or rot holes, though specific larval biology remains undocumented.
