I use this blog primarily to share nature photographs, but most people come here for my long-winded pages on scientific posters, insect hotels, and mosquitoes.

I’m a graduate of Reed College (BA) and Brown University (PhD), did post-doctoral research at Washington University and the University of Chicago, then taught evolutionary biology at Swarthmore College from 1997 to 2011.

If you’d like to browse my photographs, please visit https://colinpurrington.smugmug.com. Teachers may use any of my images in lectures for free. All I ask is that you do not crop out the watermarks and that you do not publish the images online (e.g., as part of slide decks for your students).

If my posts have brought you happiness in some way, you can send me a gift via Ko-fi or PayPal. Donations help me pay for this blog, which has been a money sink every year since I started it in 2011.

You can also find me on Bluesky and Mastodon. I share nature and science things, with occasional posts about cats, vegetable gardening, food, and travel.
