Brief description of what you observed
Born some days ago, about 1cm long :)
08 Sep 2014.
Bowman's Hill Wildflower Preserve, Bucks Co, PA.
Found on Solidago in a meadow.
I suspect that this insect is an introduced Chinese Mantis based on its size and the fact that I found it outside a building with a lot of ornamental gardening, but I would love confirmation from an insect enthusiast!
The Chinese Mantis (Tenodera sinensis) is a species of praying mantis native to China. Around 1895 the species was imported to North America for biological pest control. Tenodera sinensis often is erroneously referred to as Tenodera aridifolia sinensis because it was at first described as a subspecies of Tenodera aridifolia, but Tenodera sinensis is now established as a full species.
