Macroxyelinae
macroxyelid sawflies
Macroxyelinae is a small subfamily of sawflies within the family Xyelidae, one of the most basal lineages of Hymenoptera. The group contains two extant genera, Macroxyela and Megaxyela, with approximately six described species. These insects are characterized by their relatively large body size compared to other xyelid sawflies and their association with specific host plants, primarily hickories and walnuts (Juglandaceae). Macroxyelinae represents an ancient relict lineage with a primarily Holarctic distribution.
