Native Violets and Endangered Silverspot Butterfly
Viola glabella, Viola adunca, Speyeria zerene hippolyta
In a way, a trail of ants led me to the violets featured in this painting. I was researching ant propagated native plants, which is a fascinating topic in itself, and stumbled upon the hooked spur violet or Viola adunca, which is not only ant propagated but host to the caterpillar of the Oregon silverspot butterfly, Speyeria zerene hippolyta. This endangered butterfly lays its eggs near Viola adunca and eventually the hatched caterpillar makes its way to its only food source, hooked spur violet leaves!
I look for stories to tell in my paintings, and this seemed a worthy one, the reliance of a beautiful butterfly on a small violet for its survival. These silverspot caterpillars have lost much of their food source because of the increasing scarcity of the salt marshes and meadows where Viola adunca used to thrive. Fortunately two regional zoos are not only propagating and releasing silverspot butterflies along the coast, but planting thousands of hooked spur violets in an effort to restore the Oregon silverspot butterfly population in the wild.
The hooked spur violet forms a low, almost squat clump so I included the yellow-flowered stream violet, Viola glabella, in the painting to add height and a sense of movement. I liked the interplay of colors and different plant forms within the same family. The silverspot pollinates both violets so the stream violet is part of the story too.
The challenge of painting the caterpillar was making visual sense of all of the little hairs, or setae, and the orange spiracles that protrude from its side. I didn’t want it to become a blur of little black lines and orange dots. I decided to use shades of black to differentiate the near hairs from the farther ones. The near ones are painted a warm brownish black and the far ones bluish black because the blue tones tend to visually recede. Since the caterpillar is quite small, I used a 5x magnifying glass and a very small brush to get the fine detail and keep the image crisp. The silverspot caterpillar goes through several stages, and the one I depicted is a latter one. I’ve even learned something about butterfly life-cycle and caterpillar anatomy in this process!
So that’s how a trail of ants led me to the story of the mutual reliance of a small violet and a beautiful butterfly for survival.
