Urban Wilds

Saw this little friend molting on my screen door last night.  It was tough getting a good picture in the low light, but thankfully his discarded skin was still there today.  I think it's a wee praying mantis.  Update!  I think this is a katydid nymph based on what I've seen in the gazillion pictures on The Bug Guide.  Any idea?
