Another Butterfly Day at Spring Prairie
There’s quite a contrast between the Boisduval’s blue caterpillars almost motionlessly eating lupine pods and the frenetic activity of the ants running up and down stems and back and forth across the caterpillars. Most of the caterpillars we found were tended by these large red-and-black ants.
After the wonderful trip to the rock garden on the way to Spring Prairie in July (see Beautiful Spots on the Road to Spring Prairie), I was anxious to return to the area and check out the other spot I hadn’t been to in many years. Spring Meadow is a wetland in the drainage of Mule Creek between the rock garden and Spring Prairie. On August 3rd, Sheila Klest and I headed up Road 733. We saw lots of butterflies along the road, including quite a few at a patch of spreading dogbane (Apocynum androsaemifolium) I hadn’t known about. I definitely wanted to check it out but decided we should drive all the way to Spring Prairie first and work our way back slowly.
A few of the caterpillars had smaller ants. Although the caterpillars ranged from green to this paler pinkish color, they all had a reddish purple stripe down their back.
Wonderful Wildlife and More at Warfield Bog
Phantom crane fly (Bittacomorpha occidentalis). Crane flies have a “halter”—something that looks like a pin—where there would be a second set of wings. Although they resemble mosquitoes, they are harmless.

After some time off for my first visit to the Olympic Peninsula, I was back up in the Western Cascades on Thursday (August 18). Sabine accompanied me for a trip to Warfield Bog, an interesting wetland east of Oakridge. Last year I discovered a population of the rare swamp red currant (Ribes triste) there (see Unexpected Find at Warfield Creek Bog), and I wanted to do a more careful survey to see how much of it grows there. We relocated last year’s site easily, under a clump of firs growing near the south edge of the bog. The plants had a few unripe berries on them. We crossed the bog and headed to the northeast corner to check on the woods at the edge there. It turns out a photo I had taken there the year before had the currant leaves in them but I hadn’t recognized them at the time. We found those plants creeping along a bleached out log growing with its prickly cousin swamp gooseberry (Ribes lacustre). We actually saw six species of Ribes in the area. When we returned to the small lake by the road, we found three more patches of swamp red currant, all under trees or shrubs fairly close to the water. This is quite similar to the habitat of the ones at Park Creek I’d seen earlier in the month (see Rare Currant at Park Creek). Next year I hope to come back to see them in bloom.
