"As far as the bugs from the Jericho Dunes, I am not exactly sure what those are (and I suspect nobody really knows, yet). They might be a lupini, or most likely a texanus (if texanus proves to be a separate species from lupini as Opler believes). They look very much like the texanus that fly on the E Colorado prairie in association with Eriogonum effusum (and those may or may not be "real" texanus). The acmon-lupini group requires some major revision. While the identity and distribution of "true" acmon is probably nearly known now (basically Baja, CA, OR, S WA, far SW ID and far W NV), the various subspecies currently lumped under "lupini" in the Pelham Catalogue and on BOA probably represents 4 or 5 distinct species, at least. It will take a lot of time to sort these out... "  Andy Warren
