Moni - Thank you for the information. Quite helpful. This one stumped a lot of people.
Coneheaded katydid by: Moni
Mark
Your insect is a coneheaded katydid. It also looks like it is a female because the dark brown sharp projection on the abdomen is the ovipositor.
These katydids feed mostly on grasses but are not a pest. They are found in eastern North America in grassy areas, meadows, thickets, and marshy type areas.
Females oviposit in crowns of grass clumps where the eggs then overwinter. In MI you only have one generation per year while there are 2 in the south.
Saw a note that said they may bite when handled but I have never had a problem...but be careful when handling. :-)
Here are some photos of some of the various coneheaded katydids - http://bugguide.net/node/view/4298/bgimage
