pale swallowtail ~ 05/14/13 ~ Washington


I generally have such a hard time distinguishing between the yellow and black-colored swallowtails, especially in flight. Sometimes they flutter in wafts high up in the treetops and other times they're spastic through a natural corridor like a crazy cat chasing a laser light. I meant to ask Dr. Shapiro how he tells the difference, but I was already struggling with information overload much of the day. We also spotted western tiger (Papilio rutulus, aka Pterourus rutulus), two-tailed (Papilio milticaudatus, aka Pterourus milticaudata), and anise (Papilio zelicaon, more pictures) swallowtail butterflies.  This distinctively light-colored pale swallowtail was kind enough to be mud-puddling so that I could get a half-way decent picture.

Pacific bleeding heart ~ 05/14/13 ~ Washington

Papaveraceae (formerly Fumariaceae)

This is one of three reported larval host plants for the clodius parnassian butterfly, with the other two hosts being D. pauciflora and D. uniflora.  The last time I saw this flower was at the annual wildflower show at Big Basin Redwoods State Park's coastal Rancho del Oso in Santa Cruz County on April 27, 2013. I can't recall if I've seen it anywhere else, because when I think of bleeding hearts I usually picture Lamprocapnos spectabilis, a very popular garden flower.

clodius parnassian ~ 05/14/13 ~ Washington

Themidaceae (formerly Liliaceae)

Isn't it pretty? Those red spots make me want to pull out my art markers and draw butterfly spots. When I first saw Parnassius about 15 years ago in the Ohio museum collection where I worked, I initially thought someone had grossly misfiled the drawer in the swallowtail (Papilionidae) cabinet. I figured they should be with the whites and sulphurs (Pieridae). Wrong! They are somehow classified along with swallowtails but in their own subfamily Parnassiinae, aka apollos. After looking at the pinned labels and discovered none were found anywhere near OH and several were collected in CA, I wished I had become more familiar with butterflies before I had left my home state. Not thinking I would ever return to CA at the time, I was a little sad at the prospect that I'd probably never see one on the wing. Wrong, again! When Dr. Shapiro mentioned we might spot early seasonal individuals of this high altitude butterfly, I got very excited. There used to be ssp. strohbeeni in the Santa Cruz Mountains closer to home, but it is now assumed extinct. Sure enough, there were numerous P. clodius ssp. sol fluttering about along the South Yuba River. Yeah! I was amazed at how large they appear. This one looks very fresh and notably still slightly crumpled in the wing. As an additional note, it seems whenever Parnassius are mentioned, the butterfly version of a "closed for business" sphragis is also mentioned. For great pictures and a brief discussion of what this means, check this out.

As for the white brodiaea, I kinda surprised myself at how easily I tracked down its ID. Closer to home the coast pretty faces have made an incredible showing this year, and these white flowers reminded me of them as well as dwarf brodiaeas. I guess I'm getting slightly better at recognizing related plants.
