an obvious trendp < 0.05
Five common subfamilies (Pteromalidae: Asaphinae, Miscogasterinae, Pteromalinae; Eulophidae: Entedoninae, and Tetrastichinae) showed an obvious trend ( p < 0.05) of the FL increasing with altitude, except for Eulophinae ( p > 0.05) ( Figure S4 ), mainly due to the relatively large-sized Euplectrus , Cirrospilus, and Pnigalio generally being distributed at low altitudes ( Figure 4 ).
