I am an entomologist by training, but I am interested in just about anything that's alive. I'm obsessed with trees and the critters that depend on them. I spend a lot of time staring at trees, snags and downed logs, looking for interesting surface fauna and flora, taking a peek under loose bark or digging into beetle tunnels.

I spent most of my 30s & 40s roaming the gorgeous deserts & mountains of SE Arizona but now live in Washington, DC. I miss the large open spaces of the Southwest, but temperate broadleaf forests are my native habitat, and moving to the DC area with its lush, swampy woodlands felt a little bit like coming home to the magical forest of my childhood. I now get my critterfix and a canopy of green leaves swaying above my head on my weekly excursions to Rock Creek Park. I've been exploring the park for several years now, and I've gotten to know its creepy crawlies really well, but I still get life list firsts on just about every trip. I'm continuously amazed at the wild & wonderful things I find within walking distance of my apartment in this crowded metropolitan area. I also get a chance to chase bugs in other parts of the world when I visit my family in Spain once or twice a year and while traveling for my job.

My iNat Years In Review: 2019 | 2018 | 2017 | 2016 | 2015 | 2014 | 2013 | 2012 | 2011 | 2010 | 2009 | 2008

My Life List Firsts. The first observation for each species on my life list. Not necessarily the first time I saw a given species. Especially with common things, I may not bother making a formal observation until I see a particularly nice specimen or my fancy gets tickled in some other way.
My iNat Firsts. Observations that were the first identified iNat record for a given taxon.
My Wunderkammer. iNat Firsts where there are currently no other identified records from other observers.
Things I haven't observed yet.
My IDs for others. Other people's observations that I helped to identify.
My maverick IDs. Please help to unmaverick me!

I really appreciate the ID help I get from all the great naturalists here. Please don't be offended if I don't agree with the IDs you have provided for my observations. Ever since the separation of the taxon ID from the community ID (a welcome change), I generally only agree to IDs after doing my own research. However, I may sometimes agree blindly to move the community ID in the right direction if I trust the identifier's expertise. I think there's too much uninformed agreeing going on around here, leading to a lot of misidentified research grade observations. I don't want to contribute to that problem.

You're welcome to send me a private message if you have an inquiry or want to start a conversation, but please don't use private messages to send me ID requests. It's much better to use @ tags on observations instead, i.e., add @treegrow in a comment. I will try to help if I have time and if your pictures provide enough detail for identification. If you're tagging me on every single fly you see or tag 5 other people on the same observation, I will probably start ignoring your tags.

But I always appreciate hearing about cool things you may have done with them, and I love getting free copies of books that use my pictures (hint, hint).

All of my animal photos are of wild individuals in their natural habitat unless otherwise indicated. I generally don't catch or confine animals, but I do admit to relentless pursuit and mild harassment of reluctant subjects. After many happy years with my trusty Canon bridge camera (PowerShot SX40 HS ❤️), I recently upgraded to an Olympus Micro Four Thirds camera with the 60 mm 1:1 macro lens. I still use the Raynox 250 macro lens to get better magnification for tiny things, and I'm also experimenting with the Raynox on the 14-150 mm zoom lens. Most of my macro shots are lit with a diffused flash mounted on the camera hot shoe.

I sometimes get inquiries about collecting specimens for scientific research. I'll be happy to help out if I can. However, most of the sites I visit regularly are on National Park Service land, and you would have to get a NPS permit before I can collect anything for you.


Since I ID a lot of Diptera, people often ask me about good resources for fly identification. Unfortunately, there are way too many to list. Diptera are incredibly diverse, and there are few hard and fast rules to narrow things down because there are so many exceptions. I find the best way to learn Diptera identification is to look at a lot of identified Diptera, so you learn all the exceptions as well as the easy to ID things.

For an overview of major fly groups see ID Guide for Higher-level Diptera Groups by Even Dankowicz

For a very basic introduction to fly families try these:
DIPTERA - Description of Order and Families in British Columbia
How to Identify Flies
Key to suborders of Diptera

The best comprehensive resource for North American Diptera is available online, for free, yeah!

Manual of Nearctic Diptera Volume 1
Manual of Nearctic Diptera Volume 2
Manual of Nearctic Diptera Volume 3

There's also one for Central American Diptera, but as far as I know it is only available in bits and pieces:
Manual of Central American Diptera Volume 1
Manual of Central American Diptera Volume 2
A Manual of Central American Diptera: Key to Diptera families (adults)

For Diptera nomenclature check Systema Dipterorum


“The study of living things is not only something to pursue because it is important ... It is also a great deal of fun. To a person attuned to smaller creatures … there is no corner of nature not full of excitement, not rich in unsolved problems.”
– Howard Ensign Evans (Life on a Little-known Planet)
