Greetings! I am a freelance naturalist based in New England, and I spend as much time as I can studying obscure but fascinating insects and sharing my discoveries with the world. My first book, Tracks & Sign of Insects and Other Invertebrates, was published in 2010, and since then I have written or coauthored over 40 scientific papers, including the description of over 60 new species (see this page for a list of my publications, and this one for photos and information about all the new species). I also write a blog called BugTracks and share photos and interesting tidbits on Twitter.

In June 2019, with the help of my Patreon patrons, I completed the first edition of Leafminers of North America, a self-published 1857-page e-book that I made available in 18 monthly installments of PDFs. This guide, liberally illustrated with color photographs, provides keys to the leaf mines that can be found on every plant in the continental US and Canada, along with information about the natural history and geographic distribution of each insect species involved. In January 2020 I began releasing monthly installments of an updated second edition, which I plan to complete by June 2021. There is more information about this project, including options for purchasing the full first edition, here.

In addition to continuing to make and document new discoveries about leaf-mining insects, I have started work on a new project: a complete guide to North American sawfly larvae.  Like Leafminers of North America, it will be organized by host plant, with an introductory section giving an overview of the different groups of sawflies and their natural history. When I've gathered enough information, I plan to similarly release it as an e-book in monthly installments.

I would work on these projects full-time if I didn't have to worry about income, so your support at any level would be most appreciated.  Thank you for your interest!
