There were a couple of these creatures in this porta-potty in Franklin Park.
The most confident identification so far claims that this is Meconema thalassinum, a European insect in the group caled "quiet katydids." It's likely that quiet katydids are not so much quiet as they are singing in a pitch above what we can hear. This species is also called the "drumming katydid" since males will drum a hind leg on their substrate to make a noise, in addition to whatever "silent" singing they are doing. This species was first noticed in North America in the middle of the 20th century, on Long Island, and has been gradually spreading ever since.
