Ancestral Habitat Reconstruction and the Evolution of Maximum Speed in Relation to Habitat Preference

(A) The pies represent the probability of ancestral habitat.

(B) Speeds, in body lengths per second (bl/s), are given for both water (blue bars) and ground (green bars) locomotion, except for the terrestrial species, which cannot move on water.

Abbreviations are as follows: Pentato, Pentatomomorpha; Dipso, Dipsocoromorpha; P.apt, Pyrrhocoris apterus; C.ali, Cryptostemma alienum; M.fur, Mesovelia furcata; H.sp, Hebrus species; H.sta, Hydrometra stagnorum; S.str, Stridulivelia strigosa; S.ter, Stridulivelia tersa; P. bra, Platyvelia brachialis; O.cun, Oiovelia cunucunumana; P.bul, Paravelia bullialata; P.con, Paravelia conata; H.tur, Husseyella turmalis; M.ame, Microvelia americana; L.dis, Limnoporus dissortis; G.bue, Gerris buenoi; A.pal, Aquarius paludum.

Samples sizes in terms of number of videos are given in Table S1. Error bars represent standard deviation. See also Figures S1 and S4 and Tables S1 and S2.
