Greetings! I saw this in mid August in a Cypress swamp in Hilton Head, SC. I thought it was a grasshopper, but then I started looking on your site and realized that it is a Katydid. A Red-headed Meadow Katydid?? Just a wild guess. thanks. I love your site.
According to images posted to BugGuide, we believe you have the genus correct, but that this is a different species of Meadow Katydid. We favor Orchelimum minor.
Update: (07/03/2008) Katydid IDs from Piotr Naskrecki
I have been looking at the page with unidentified katydids (Katydids 2), and thought I could help with some ID’s. From top to bottom they are: Meadow katydid – Orchelimum (possibly eythrocephalum, but this is a nymph)
