Blister Beetles

Zonitis sayi, copyright Carol Davis. This is a blister beetle of the genus Zonitis.

Zonitis is a widespread genus of blister beetles with over 100 species described from around the world. However, it should be noted that its wide distribution may relate to the genus being poorly defined and future revisions may divide its members between other genera (as I believe has already happened for the Australasian 'Zonitis').
