Fig. 4 in Phylogeny of Maculinea blues (Lepidoptera: Lycaenidae) based on morphological and ecological characters: evolution of parasitic myrmecophily

Fig. 4. Evolution of the life history traits of Maculinea butterflies and their relatives. Only the species for which states of all relevant characters are reliably well-known are included (see Table 1), but the overall topology of the tree including all terminals (Figs 2 & 3) is preserved. (A) Myrmecophily. M. nausithous is optimized as a modified predatory species (see ''Evolution of life histories''). (B) Host plants and habitat associations. Rosids and asterids are two well-supported clades of eudicot angiosperm plants (see Angiosperm Phylogeny Group, 2003): Fabaceae and Rosaceae are included in the former, Lamiaceae, Gentianaceae, and Campanulaceae in the latter. In some cases, character-state optimization is derived from the all-species tree (Fig. 3).
