Eric R. Eaton is author of Wasps: The Astonishing Diversity of a Misunderstood Insect (Princeton University Press, 2021), lead author of the Kaufman Field Guide to Insects of North America (Houghton Mifflin Company, 2007), co-author of Insects Did It First (Xlibris, 2018), and contributor to several other books including The Butterfly Gardener’s Guide (Brooklyn Botanic Garden, 2003) and Wild in the City: a guide to Portland’s natural areas (Oregon Historical Society Press, 2000). He has also written articles about insects and other animals for Birds and Blooms, Ranger Rick, Missouri Conservationist, Timeline (journal of the Ohio Historical Society), and other magazines.

Mr. Eaton studied entomology at Oregon State University, and has worked as a professional entomologist for “Butterfly Magic” at the Tucson Botanical Gardens, Chase Studio, Inc., and the Cincinnati Zoo. He has worked on private contracts for the University of Massachusetts (Amherst), West Virginia Department of Natural Resources, and Smithsonian Institution.

He enjoys the respect of his network of professional colleagues, and has built a loyal following in social media (Facebook and Twitter), and as a volunteer expert and consultant to WhatsThatBug.com, and AllExperts.com (where he was one of the top 50 experts for the year 2009), and Bugguide.net. His empathy for the squeamish and scared, knack for identification of mystery bugs, and his accurate, jargon-free explanations of insect biology have made him a leading figure in popular entomology.

Mr. Eaton is available for speaking engagements, media interviews, field and laboratory workshops, and contract work preparing and curating preserved arthropod specimens. He welcomes writing or editing assignments for publications, websites, and other media.

Eric currently resides in Colorado Springs, Colorado, with Heidi Eaton. He lived previously in Portland, Oregon; Cincinnati, Ohio; and Tucson, Arizona.


  1. Thank you. Are you using this method yourself?

  2. wow.. I love your pictures and words.. thank you for sharing!

  3. Thank you! I love insects, and your site and compassion are invaluable to me. All blessings to you and your family.

  4. I love your articles. Please, never stop writing them. I am a pest control entomologist and received some small wasps that were in a sliding door frame. From your article, I found out they were aphid wasps. Cool!

  5. Help! There’s a new Tachytes nest outside our front door. A new puppy, 3 dogs, and 2 cats come and go from that door. What do you advise? Keep in mind, we are avid pollinator habitat restorers, with acres of it around our property. Also, I raise monarchs. The wasps (in significant numbers) won’t affect them, will they? Thanks for any and all guidance!

    Help! New Tachytes nests outside the front door. New puppy, 3 adult dogs, and 2 cats come and go from that door. We are restoring acres of prairie for pollinator habitat, so any and all are welcome—as long as they leave the mammals alone! What should we do? Also, raising monarchas. Tachytes won’t bother them, right? Thanks much for any and all advice!

  6. Hello Eric, I am not sure if you are still writing on Cat Head Spiders. but I have had one that has lived on my screen sense the summer of 2018, she did survive the winter and now has made her home up in the corner of the roof, she has her egg sac all made and stays near it. I understand once a female has her eggs the pass with the very first frost..which will be soon~ We will miss her, and we will miss watching her, we feed her flies....She has really touched our lives and we will never forget our "SpiderGirl"~

  7. What insect would you say you most-closely resemble - both in appearance and behavior?? :oD

  8. Would you please identify a bug for us?

    1. I do that kind of thing on Facebook and iNaturalist now, and that's about it.
