Checkers and streaks

You guessed it tonight's post features butterflies seen at The Cedars on 25 April 2015. 

First, the checkerspot:

I'm pretty sure these are Edith's Checkerspots (Euphydryas editha).  However, I'm a little hampered without access to my field guides right now.  If you think this identification is wrong, just let me know and I'll correct it (I'm happy to hear about confirmations, too!).

They were actively nectaring on Yerba Santa (Eriodictyon californicum).

Next, the hairstreak:

Muir's Hairstreak (Callophrys muiri) is a serpentine endemic.  Its host plant at The Cedars is probably Sargent Cypress (Hesperocyparis sargentii).

I had trouble photographing the hairstreaks, but I'm including one more image below:

And for the record, I also photographed a duskywing:

My guess is Propertius Duskywing (Erynnis propertius).  But I'm open to other ideas, as I don't have a lot of experience with duskywings in California yet.

Here's one more picture of it — not great, but it shows the light spots in the wings that are useful for identification:

Although none of these butterflies are likely to be found on Bodega Head, it's fun to think about them in The Cedars, only about 20 miles away.
