Katydid on My Knuckle

Most of the time when I am slogging through the tall grass at Valley Forge all the katydids hop away as fast as they can.  But a few days ago, I found one looking for a friend.

This guy was perched on a stem, facing the wrong direction for a portrait.  I  gingerly put my finger near his face and he jumped on and would not let go.    I tried over and over to put him back on the stem, but if I got him back he would walk dejectedly away in the wrong direction.  So I put my finger near him again and he jumped back on and stayed.  Finally I gave up and just took the picture.  (Click his face for better view.)
