This the Karner Blue Butterfly (Lycaeides melissa samuelis), a federally listed endangered species in New York State. This image was captured in 1979 on Kodachrome 25 in the Albany, NY, Pinebush Preserve, and scanned a few years ago for digital reproduction. The lighting results from the electronic flash being close to the subject, and thus brighter than normal sunlight. This was the hot style at the time, and I have to say, allowed small f/stops for good DOF, and fine action stopping power. The biggest challenge is getting the film plane parallel to the plane of the wings. The Pine Bush is a relic of the end of the last glacial retreat and is the sandy 'river delta' of the Mohawk River as it emptied into glacial Lake Albany. Melville mentions this 'illimitable pine barrens' in Moby Dick (Ch 53). It is one of the best examples of an inland pine barrens ecosystem in the world. Fortunately, it is now easily accessible, and graced by a joint state and city effort to maintain it's unique ecological nature.
