The first photo I’ve seen of Brood XIX Magicicada so far in 2011. Appears to be a Magicicada tredecim.
Abbeville County, South Carolina
You can see this insect on Bug Guide as well.
Update (4/19): here’s the second photographed adult. This one is from Virgina I believe. Right now adults should be showing up here and there, but it won’t be for a few more weeks before things get crazy.
Update (4/26): there’s lots of Brood XIX photos showing up on Flickr now. I started a Brood XIX Gallery in an effort to keep track of them.
