Butterflying on Coal Creek Road

We couldn’t go up Coal Creek Road without checking out the amazing spreading dogbane (Apocynum androsaemifolium) patch just past the 4-way intersection at the top of the crest (43.3998°N, -122.4561°W). We delighted in the abundance of butterflies and the intoxicating fragrance of the flowers. While most of the visitors were checkerspots, we also saw some fritillaries, parnassians, coppers, and all three of our “ladies,” including this American lady.

Julia’s orangetips rarely sit still long enough to photograph them, so I was really pleased to capture this lovely male who was making the rounds of the tall bluebells (Mertensia paniculata) growing in the roadside ditches.

Coal Creek Road 2133 which leads up to the west end of the Calapooyas is one of my favorite places to do roadside botanizing and butterflying. It’s also one of John Koenig’s, so on July 13, we drove up there for an easy day as John was still recovering from some foot issues and wasn’t up to a real hike. It was warm, but there was still enough moisture in the many seeps and creeks along the road to nourish the flowers, which in turn attracted lots of butterflies. Here are some photographic highlights.

We scared up a family of grouse along the road. The cute babies all flew up into the trees.

John spotted this lovely mating pair of lilac-bordered coppers near the waterfall on the way up the road.

We saw a great display of beargrass (Xerophyllum tenax) by what I call “Dead Toad Pond,” a shallow vernal pool east of Loletta Lakes. There was no water left where it collects in the area beyond the beargrass but also no sign of dead tadpoles this year. Contrast this with last year on exactly the same day after a much wetter spring when the pond was filled with water and teeming with tadpoles (see Saxifrages and Toads near Loletta Lakes). Also in good bloom in the area was the beautiful subalpine spiraea (Spiraea splendens).

I originally thought this hairstreak sitting in the water of a small cascading creek was the rare Johnson’s hairstreak as I had once seen one in this area, but it turns out to be the very similar thicket hairstreak. According to Neil Bjorklund, “key field marks being the very pronounced M in the white ventral hindwing median line, and the dark spots that go nearly all the way up the outer margin of the VHW.” The caterpillars of both species feed on conifer mistletoes (Arceuthobium spp.).

We were very happy to see that the area along the road that had been scraped up a few years ago had recovered so much that it was hard to tell anything had happened. The clumps of cliff paintbrush (Castilleja rupicola) growing in the road were still doing really well.

Clodius parnassians are one of my favorite species of butterflies. Their wings are so elegant. The transparent areas are unique among the Western Cascade butterflies.

I was warned about this bad spot in the road by Chuck Hefflefinger, who also frequents this area. It hadn’t been there when I drove up last year. I was glad John was able to drive his truck as I don’t think my car has enough clearance for the high ridge in the middle. I love exploring the area along this road, but the road itself is often a problem. The Forest Service doesn’t enough manpower to fix individual spots just because some of us have vehicles that can’t handle the rough spots.
