Butterflies: Yuba Pass, Sierra County, CA - June 27 through 29, 2003

I'm still a novice at identifying butterflies and their plant relationships. So, if you disagree with the name I've put to the following butterflies photos, please send me a note to explain. I'd like to learn something new. Please do not copy any image without first asking for permission. All photos © 2003 Les Chibana.

These are some of the butterfly sightings made during my BirdNutz trip to the Yuba Pass area this summer. The group shots were taken near Bassett's Station within a few feet of the North Yuba River. It's been suggested that they were drinking, but there was no puddle of water visible. Could they have been acquiring some minerals?

Lorquin's Admiral and Spring Azures? (Limenitis lorquini and Celastrina ladon?)

Another shot of the Spring Azures? below.    
     
  As you can see, there wasn't any puddle of water despite the proximity of the river, a couple of feet to the right. Any ideas what a mixed group of butterflies were doing on the ground in clusters?
     
     

Is this a California or Sylvan Hairstreak (Satyrium californica or S. sylvinus), or perhaps something else? It's tailed and the hind underwing is coppery.

  Same individual feeding on a white brodeia with some buddies.

Is this a California Crescent (Phyciodes orseis) on some kind of clover?

  Same as the one to the left, but this is what it looks like when I'm not wearing my contact lenses. This poor image is still useful!
