I talked with a birder several years ago who was also an amateur artist. We were on a field trip to Amherst Island, where there\u2019d been reports of a Eurasian Wigeon. At the time, this was a life bird for me, so I was understandably excited. My companion was indifferent. He wanted to talk about the much more common American Wigeon, whose plumage fascinated him. As an artist, he found the bird a challenge. The color of the breeding male\u2014on the back and along the side\u2014was indescribable and almost impossible to duplicate in a painting.<\/p>\n
\u201cIt\u2019s actually a very delicate shade\u2014it doesn\u2019t correspond exactly to any watercolor or oil paint that I know of. The only way to get it is by mixing colors, but good luck with that. I\u2019ve been trying for years without success.\u201d<\/p>\n
David Sibley describes the shade as a \u201cpinkish-brown,\u201d and I suppose that\u2019s as close as we\u2019ll get to this subdued but glowing color that also contains suggestions of grey and orange. Let\u2019s call it one of nature\u2019s triumphs\u2014a color that\u2019s impossible to duplicate or describe with absolute precision.<\/p>\n
I thought of this conundrum last week, when I saw a Harvester for the first time, the tiny butterfly that\u2019s usually identified as \u201cthe only carnivorous butterfly in North America.\u201d It\u2019s actually the caterpillars that are carnivorous, if that\u2019s really the word we want. They eat wooly aphids that infest alder trees, especially in habitats that are damp or marshy. The butterflies content themselves with feeding on the sugar solution secreted by the aphids. They\u2019re also known to seek out rotten fruit and animal dung. Only rarely do they nectar on flowers.<\/p>\n
The Harvester\u2019s underwing presents the same difficulty of description as the American Wigeon\u2019s plumage; in fact, the colors are somewhat similar. On the butterfly, the base color has been described in the field guides as \u201cred-brown\u201d or \u201corange-brown\u201d or \u201cpurplish-brown.\u201d Let\u2019s call it purplish-brown with at times an almost greenish tinge or highlight. What complicates the description even further is the presence, on the underwing, of \u201cmany darker spots finely edged in white.\u201d The Harvester\u2019s upperside is more straightforward and bolder\u2014a fine, bright orange bordered, and in places spotted, with dark brown. And let\u2019s not forget the checkered leggings that, along with the black eyes rimmed in white and the black-and-white antennae, give this butterfly a raffish or natty air, as if it just stepped out of a P.G. Wodehouse novel. When I told somebody I was looking for a butterfly called the Harvester, she said, \u201cOh, what color is it?\u201d Rather than attempt a description, I suggested she look up photos on line.<\/p>\n
