This photo, at least on my screen, is the actual size of this little beast.
On October 1st, not far above the “four-way,” on the road to the Seven Bridges Trailhead, I came across this neonate smooth green snake, total length 110 mm. This makes it a late summer brood hatchling, smaller than the average given in Redder, et al. (2006). In my experience, this little species is rare in this region, but according to various studies cited in Redder, its population densities can reach at least 75 per acre. Imagine that. So around here, in a grassy swale near water, in the area the size of a football field, there might be, say, 20 or 30 of these little guys, and we never see them. Almost never. They eat insects and spiders. Keep looking. Most snakes occur in populations much larger than us non-herpetologists imagine. We just don’t know how to find them.
