small, about 4cm, dark brown, living on the ground, bite mark shown in photo 2 and 3 showing its mouthparts
humid tropical forest
It was the dry season during most of my travels through Asia but the forest in Ba Be Lakes National Park was humid enough for a few leeches to be around. I discovered this one on me and then put it on my hand to photograph it. While I was getting ready for the shot, the leech bite me and began to feed. I pulled it off after I got a few shots but the bite continued to itch periodically for weeks.
