B.A. in Biology. Worked in pharmacology, now retired. Lifelong addiction to identifying life-forms. Love taxonomy. Obsessed birder since 1999. Previous preoccupations with turtles, cacti, flora. Began studying bugs in 2012, when I discovered what they look like with a digital camera, and that I could contribute to public understanding of their distributions through websites such as BugGuide and iNaturalist.

I live in Buckingham Twp, Bucks Co, PA., and most of my recent observations are from local sites. I photograph and identify to the best of my ability any plants and animals I encounter. To give back to the community, as well as to increase my own expertise, I try to identify some groups for others. I am currently making ID's for Nippotipula of North America and Diptera of PA and NJ. I am very happy to answer any questions about ID's I have made.

When I die, I would like to have all my images and other content remain on iNaturalist. I have always been amazed at the incredible diversity that God has created, and I hope that my feeble efforts to highlight some of that diversity will help others to appreciate the magnificence of God.
