Host plant specificity can vary greatly across butterfly species, ranging from only 1 plant species to dozens of suitable plant species. Host plant specificity can promote speciation between two or more groups of closely related through reproductive isolation. Prime examples of this are Euphilotes blue butterflies and some Apodemia metalmarks that almost exclusively use different species or varieties buckwheats (Eriogonum) as larval hosts. A similar situation has been demonstrated in Mitoura hairstreaks that feed on trees in the family Cupressaceae (junipers, incense-cedar, cypresses).">host plant</acronym></a> is present and there are breeding populations around nearby Lake Berryessa.

For our purposes, groups of interbreeding or potentially interbreeding populations of individuals that share an evolutionary history and ancestry. However, there is significant debate on what exactly constitutes a species and many definitions and concepts have been proposed. The most common of these is the biological species concept, which requires that sets of populations must be able to successfully and regularly interbreed and produce viable, fertile offspring.">species</acronym></a> often occurs on <a class="glossary-term" href="/glossary/3#term167"><acronym title="A rock type derived from subducted ocean floor material that are characterized by unusually high concentrations of magnesium, chromium, manganese, cobalt, and nickel. Sodium and calcium are in unusually low concentrations. As a result, few plants are able to grow on these soils, and those that can are usually “edaphic endemics” (see above) and exhibit stunted growth patterns. Serpentine habitats also frequently are home to unique animals (for example see the Sleepy Dusky-wing or Muir’s Hairstreak).
