The leech in the first 2 photos had got my 'scent' and was stretched out, waving around trying to get my direction. In the last 2 photos they are at rest, and have contracted. It was wet in the park, muddy underfoot, and these leeches were waiting on the edges of leaves bordering the path. The darker leeches I have seen, seem to wait on the ground. Tiger Leeches are easily recognized by their longitudinally striped reddish brown dorsum: there is a broad, bluish-gray, yellow-greenish, or multicolored median-paramedian field that contains three to five black or dark brown broken stripes inside. There is also a white or pale yellowish longitudinal marginal stripe with dark-spotted borders. The venter is uniformly yellowish brown. I had only seen dull dark ones before. These ones had a magnificent pattern.
