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. photo details: Canon MP-E 65mm 1-5x macro lens on a Canon EOS 20D ISO 100, 1/250 sec, f/13, indirect strobe fired into white box
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. photo details: Canon MP-E 65mm 1-5x macro lens on a Canon D60 ISO 100, f/13, 1/200 sec, flash diffused through tracing paper
