This one is particular was trying to reach out to me.  They usually hang out on leafs just on the side of trails and when they sensed heat, they starts reaching out and if they feel they are close enough, they would even let go to drop to you.

Aside from the continuous blood flow if they get to bite you, this bites from tiger leech may leaves you feeling severely itchy for days and weeks!

During all my walks in the Park, I had to be fully covered, including wearing hat, gloves and applying menthol-based lotions on my face and neck as I noticed they don't like the stings of menthol. Fall,Geotagged,Haemadipsa picta,Leech,Malaysia,Sabah,Tiger Leech
