Exciting Day at Spring Prairie

On July 25, Nancy Bray and her husband, Herb, invited my husband Jim and me to join them on a trip to Blair Lake and nearby Spring Prairie. It was a bit hazy from fires to the south but otherwise a lovely day. When we got to the intersection of Road 733 that goes up to Spring Prairie, we made a quick decision to go up there first. I was pleased to see the road was in better shape than I remembered (no more trench down the middle of one section) as it had been quite some time since I’d driven up there although I had walked up the trail from Blair Lake last year (see Beargrass Season at Blair Lake).

We drove straight up to the edge of Spring Prairie and parked the car. On getting out, I immediately noticed lots of butterflies flying about in the large, mostly beargrass (Xerophyllum tenax) meadow. Other than some fireweed (Chamerion angustifolium) blooming farther downhill, nothing was in flower. So what were all these butterflies doing here? Growing among the beargrass was quite a bit of lupine (Lupinus sp.) with immature fruits. The butterflies all seemed to be Anna’s blues (Plebejus anna). If you guessed that they use lupines and other legumes as host plants, you’d be right. They appeared to be mating and laying eggs. I started searching the plants carefully. It took only a few minutes to spot the first egg, looking much like a tiny white sea urchin shell after the spines fall off. I’d never seen one before, but I recognized it from the similar hedgerow hairstreak eggs I’d seen a couple of years ago. What a great start to the day! I continued to look for eggs and found quite a few more, laid on stems and pods as well as leaves. Read the rest of this entry »
