Raised by two scientist parents, Evans has had a lifetime interest in studying and collecting flora, fauna, rocks, minerals, fossils and other artifacts from the natural realm. Evans' particular fascination with insects dates back to childhood adventures: collecting large silk moths attracted to the outdoor lamps at night, searching for beetles and other creatures under overturned rocks, and capturing "pet" praying mantises from the bushes of his suburban home. Evans is keenly aware of the current rapid collapse of insect and bird species populations around the globe, suggesting they could vanish within a century. With this imminent peril in mind, in addition to being captivated by the intricate architecture of their exoskeletons and diverse range of color and patterning, Evans also utilizes insect imagery to mine potent artistic metaphor. Using a variety of formats, including multi-panel narratives, Evans explores and confronts such issues as environmental collapse, the ephemeral nature of things, metamorphosis and change, and the threat of human activity on a fragile ecosystem. In addition to insects, Evans also examines birds, plants, rocks and other natural artifacts through a similar lens.
