Chrysomelidae
Zygogramma leaf beetles, Arizona
Leaf beetles such as these brightly marked Zygogramma constitute one of the largest evolutionary radiations- the Chrysomelidae- among all animals. This family of beetles owes its tremendous diversity to an herbivorous association with flowering plants.

Chrysochus auratus - Dogbane Leaf Beetle
New York
At first glance one might mistake the dogbane leaf beetle for a creature of the tropical jungle, an exotic jewel sought after by the most discerning of collectors. But no. It's a rather common beetle in northeastern North America, where it feeds on plants in the Dogbane family Apocynaceae. I photographed this one a few years ago on a rainy summer day in upstate New York.
