more related to climate than to host plant association, whereas both factors seem to affect diversification. Beccaloni GW, Symons FB (2000) Variation of butterfly diet breadth in relation to host-plant predictability: Results from two faunas. Results with a traditional phylogeny were very similar (global test.132, 4 of significant links for matrix A and.002,.8 of significant links for matrix X but with the alternative 2 phylogeny, both matrices were significantly congruent (global test.042 with.8 of significant.

Recent combined morphological and molecular analysis suggests that the true butterflies are paraphyletic and the superfamily Papilionoidea has been redefined to include all seven families 26,.

Janz N (2011) Ehrlich and Raven revisited: Mechanisms underlying codiversification of plants and enemies. Calyptra and if there is, in fact, a directional progression of feeding types in these moths. Under this scenario, there have been just a few secondary gains of monocot feeding among dicot-feeding lineages, and only a few reversals back to dicot feeding among monocot-feeding lineages. Lycaenidae was the honors college thesis learn second largest butterfly family, with 5,076 species (4,109 with distribution information most of them present in AT (33.7 and OR (26.1) regions. In general there was a significant (p.001) and strong positive correlation between host plant diversity measures and the logarithm of butterfly species richness. This phylogeny will be used to check the existing higher-level classification (tribes, genera) and propose changes where necessary. Clearly the completeness of the present database was only possible thanks to the availability of digital resources, which represent an important opportunity for the analysis of biotic associations. Later on it was recognized that other evolutionary scenarios could also explain the patterns observed. Within NT, Hesperiidae and Pyrginae were richer in species, but Pyrrhophyginae, Heteropteriinae and Eudaminae were also well represented.
