Schematic drawings of different types of setae found on leg sections of Rhagovelia distincta and Gerris latiabdominis that interact with the water surface. (A) Microsetae, m. (B) Macrosetae 2, M2. (C) Grooming comb, G. (D) Cuspidate setae, C. (E) Stumped setae, S. (F) Macrosetae 2, M2. (G) Hook setae 1, H1. (H) Hook setae 2, H2. (I) Spoon setae, Sp. (J) Obtuse setae, O. (K–L) Macrosetae 1, M1. (M) Thorn setae 1, T1. (N) Thorn setae 2, T2. (O) Thorn setae 3, T3. (P) Web setae, W. (Q) Leaf-blade setae, L. (R) Leaf-like setae, l. (S) Grass-blade setae, g. Alphabetical labels correspond to SEM photos in Figure S10 and morphological data in Table S3. Setae found in both species are labeled in black; those found only in R. distincta are in blue; and those found only in G. latiabdominis are in green. Note that scales vary between panels and are specified for each seta type. Descriptions of all seta types are provided in Supplementary Information Part 3 C.
