This week, we turn our attention to the insect order Lepidoptera (butterflies and moths). Our featured insect is Zerene cesonia, the dogface sulphur butterfly. It is classified in the family Pieridae. 

This butterfly is often found along roadsides. Adults drink nectar from plants such as alfalfa. Caterpillars on leadplant, alfalfa, false indigo, soybean, clover and a number of related plants.

The wings are yellow with black borders. Here we have a good example of pareidolia (the ability for humans to perceive an image from a random pattern). Am I the only one who sees the profile of a dog in the patterns on the front wing?
