This is a lovely little Pierid species which occurs largely in the southern counties of my state (Illinois). It is thought that Illinois winters are too cold for the species to survive; thus, it must recolonize the state each year from the south. Prior to the early to mid-70's hobbyists like myself could find the species quite readily as it was present from early April thru early November; having several generations. However, since that time the species has had a steep decline in numbers and frequency thus it is no longer common. Today, seeing one or two would be a very good year for an Illinois butterfly enthusiast. This butterfly's common name is from its upperside wing pattern -- as it was thought that the forewing's black crescent resembled a sleeping or closed eye. When disturbed these little fellows have a flight which is quite rapid. Males patrol ditches and flat areas seeking a female. Below, in the 1st photograph I exhibit the only extant specimen which this collector has encountered over these many years... A tough find generally speaking but, the right time and place could possibly produce many nice fresh examples. Here, is a photograph of a good friend's holdings of this marvelous boldly colored species. My friend has had quite a bit more luck than I over the years as his proximity to the southern counties (where the species is mostly seen); is 1/3rd less the distance I must travel in any hope of finding it.
