Maximum likelihood optimization of larval habitat on the topology from Figure1(pruned to include only one terminal per species) analyzed with Mesquite using the AsymmMk model of character evolution. Only character states that are statistically significantly better than the others are shown along the branches. A solid (one color) node indicates that state is significantly better than all other possible states. Numbers after species names are specimen numbers (Table 1). Lagrange-estimated ancestral charater states are denoted by blue (aquatic) and black (terrestrial) boxes. Only those nodes with a single state estimated to be significantly better than all other states are plotted. The full Lagrange output is shown in Additional file 1: Figure S5.
