Small Green Stink Bug - Piezodorus guildinii

Small Green Stink Bug - Piezodorus guildinii
Gainesville, Florida, USA
November 16, 2004
Perhaps I'm jumping to a hasty ID here, but I think this is Thyanta based on a very similar image on the University of Kentucky entomology site .

Ha! We're ALL wrong:-)
I had my friend, Dr. David Rider, a stink bug expert at North Dakota State, look at this. He says it is Piezodorus guildinii, native to South and Central America, and the southern U.S. It is apparently quite common in FL, and sometimes considered a pest. Go figure:-)

Thanks, Eric!
That makes perfect sense since I photographed this guy on Indigofera, which is one of the legumes listed as a host. I will relocate to an appropriate place in the guide.

Many species of Banasa have a very similar color pattern. If I can get this ID'd by an expert, I might want the image for the field guide I'm working on, Hannah.

Thanks to both of you -
unfortunately I have no good bug reference books, so I hope you can sort this one out for me.

Banasa vs. Thyanta
Well, looking at the illustrations in Slater (1), Banasa is in figure 69, p. 49; Thyanta fig. 76, p. 51. Eric again shows his awesomeness! In your photo the form of the pronotum and the shape of the "nose" is a dead ringer for Slater's illustration of Banasa. Slater has a key system, but those two genera are a couple of steps apart, and the key is based on characters of the scent glands and antennae, not readily observable in your photo.

Again, I'm just looking at the pictures, but I'd say it's Banasa. Perhaps careful examination of images below would be useful. (Insects of Cedar Creek would be best, but the server is down right now.)

Some Internet references, Banasa:

Pretty, print references
Neat photo. Two references:
