Biological Illustration

Drawings and paintings

Wayne Maddison

I’ve been drawing spiders since I was a young teenager, and late in my undergrad career did many illustrations, most for a never-completed project for Agriculture Canada. I also made many illustrations for my dissertation (on the jumping spider genus Pelegrina). To me, the drawings not only help me learn the structure of the animal much better than casual inspection, but also celebrate its beauty — a celebration that I think is
important if we are to build an appreciation of the living world around us, and choose to preserve it.

Other illustrations of mine can be seen in the Pelegrina pages of the Tree of Life and the pages for HabronattusHabronattus coecatus, H.notialis, H. calcaratus, H. trimaculatus, H. pugillis, and H. alachua.
