I took this picture of an iridescent beetle at the Iguacu Falls in Brazil.
Can you please identify it.

Dear Ian,
This is a Tortoise Beetle in the tribe Cassidini, and it is similar to this individual on Insetologia. We located an image on FlickR of Cyrtonota cyanea that looks like a very good match to your Tortoise Beetle. We found an image of a mounted specimen on Cassidinae of the World, but dead specimens of Tortoise Beetles often lose their beautiful coloration.

Oh, thanx for the link!
It would be good to see it from above.
Daniel, here is a good source for Brazilian museum specimens, it’s helping me a lot:

Unfortunately, we have to check the individual links to see the images, then we gotta be patient.
