Welcome to the Chironomidae and Water Beetles of Florida Web Site!
28 YEARS ON THE WEB !
The midge adult above is Dicrotendipes thanatogratus,
named by me in 1987 for the Grateful Dead!!!
Here you'll find current information on the taxonomy and distribution of these wonderful groups of insects in Florida and elsewhere.

Information on taxonomic workshops
Hi! I'm John Epler. I've been working with aquatic insects, and Chironomidae (non-biting midges) in particular, for over 45 years, as well as with water beetles for over 20 years. I work as an independent researcher/consultant - although I have written aquatic insect identification manuals for the states of Florida and North Carolina/Southeastern US, I am not employed by any state or federal agency. Since earning my Ph.D. from Florida State University over 30 years ago, I've been able to make a living by identifying aquatic insects and writing books/manuals on how to identify them. This work has enabled me to fund my own research describing new genera and species of midges and water beetles. On this web site you'll find a small sampling of the results of my research from the past four + decades.
