Our <a class="glossary-term" href="/glossary/3#term175"><acronym title="A line along which environmental data is collected. In this study, the 10 locations that have been regularly sampled for butterfly diversity is roughly along a transect line paralleling U.S. Interstate 80 from the eastern San Francisco delta through the Sacramento Valley, and up and over the Sierra Nevada mountains.">transect</acronym></a> is right at its southern range limit in California. There appears to be a small population near Washington, Nevada County which was discovered only a few years ago (though it was probably there all along; it occurs at low density and is not seen every year). There may be others on the West slope in similarly cool, wet, shaded places. Adults sit in sunflecks and visit flowers, particularly native vetches which they pitch up onto from below. The larval hosts are presumed to be native grasses. There is one <a class="glossary-term" href="/glossary/3#term86"><acronym title="The description of how many broods (generations) per year a particular butterfly species produces at any one location. A butterfly with one generation per year is “univoltine”. Butterflies with two generations per year are called “bivoltine” and those with more than two are generally referred to as “multivoltine”.">brood</acronym></a> in early summer (May-July).</p> Carterocephalus Sun, 28 May 2006 18:09:37 +0000 admin 33 at http://10.70.15.71
