Figure 1

The morphology of the hind wing of H. axyridis is composed of a wing membrane, veins and a pst. (a) H. axyridis hind wing. Scale bar: 1 mm. (b–j) Cross-sectional structures of psts. Scale bar: 50 μm. (k) Simplified model of the veins and pst based on the location marked in brown. ScP: subcosta posterior. RA: radius anterior. RP: radius posterior. RP2: radius posterior 2. MP1 + 2: media posterior 1 + 2. AA: anal veins. CuA: cubitus anterior. cb: costal bar. arc.c.: complex arculus. pst: pterostigma. ams: anteromedian sclerotization. cs: central sclerotization. aas: antero-apical sclerotization. pcas: postcosto-apical sclerotization.
