Too much time in front of the computer lately, so a quick trip to Crex Meadows Wildlife Area in Wisconsin was in order. 

My main target was the OLYMPIA MARBLE, a small white butterfly that doesn’t look like much while flitting about a grassland, but when it lands it reveals the stunning underwings that are marbled with a glittery green/gold.

Because of my research on Mike Reese’s wonderful wisconsinbutterflies.org site, I found several only two minutes after I arrived. Hmmmm, this will be easy, I thought. But I quickly found out that these butterflies are very particular about which flower they land on…and it takes them a loooong time to do so.

Their host plant is Rock Cress (Arabis sp.), a 6-12″ unassuming plant with a few groups of 4-petaled white tiny flower at their apex. And there were many in full bloom in this patch of grassland.

With camera in hand, and flash ready to fire, I would follow a flying Olympia Marble across the prairie waiting for it to land on a Rock Cress after which I’d drop to the ground, prone on the prickly prairie, to get an eye-level shot of a stunning butterfly. But 9 times out of 10 (19 times out of 20?) the little butterfly would already have moved on by the time I was in position. The few times it did begin to nectar, it only did so for a very few seconds, leaving while I was still trying to focus on the very tiny flowerhead. I was left to grunt and groan as I tried to get back onto my feet to pursue it yet again.

Not only this, but I failed to realize that while the mosquitoes had not yet emerged in northern Minnesota, they were out if full force at Crex, and they were joined by their friends the Black Flies. No bug dope in my van. Zero. Despite the 75 degree temps I had to don my wool Ullfrotte jacket. Not comfortable.

I still wonder why the Marbles pass up countless Rock Cress that look perfectly fine to me….What do they know that I don’t? Are some already stripped of nectar? If so, how do they know? Smell? Look? 

Finally I was able to get in position and click off a few frames on a couple occasions. It only took 2 hours but I finally had a satisfying image showing the glorious underwings.
