Vittarioideae worthy of subgeneric rank, while "Rheopteris" had not yet been discovered. "Haplopteris" he explicitly synonymized with "Vittaria" in 1914. Carl Christensen used the name "Vittarioideae" in Verdoorn's "Manual of Pteridology" in 1938, but did not include a description, leaving it nomenclaturally invalid. Ren-Chang Ching raised Vittariaceae to the rank of a family in 1940. The first well-sampled molecular phylogenetic study of the vittarioids was based on the chloroplast gene rbcL. In this study, it was found that the type species of "Monogramma" is embedded in "Haplopteris"; the segregation of "Vaginularia" from "Monogramma" was also supported, as members of "Vaginularia" formed
Larval food plants of Lepidoptera (which often have to be abundant enough). Lepidopteran larvae can often be raised on a variety food plants and commercial mixtures. Closely related Lepidoptera tend to have similar food plant preferences. Many caterpillars sequester the toxins from their food plants and use them as a defense against predators. Though it is common for Lepidoptera to prefer a certain plant genus or family, some species feed on a narrow selection of unrelated taxa. The choice is unrelated to nectar plant preferences of adult Lepidoptera, which are much less strict. Larval food plants of Lepidoptera Caterpillars (larvae) of Lepidoptera species (i.e. of
