Interests and Expertise

I am interested in all aspects of aquatic insect biology, especially the resolution of species using genetics, reproductive biology, and life history data. I have also combined my interests in entomology and photography to produce a large collection of images of aquatic insects in their native habitat.

Photography

I have been taking pictures of insects for more than 30 years and have developed special equipment such as a shallow underwater rig (pictured below) for taking in-stream photos aquatic insects. My photographs have appeared in numerous books and magazines, including Natural History, Scientific American, Ranger Rick, National Wildlife, Wings (Xerces Society), BBC Wildlife, and Nature Australia.

: Ameletus ludens mayfly larva photographed in White Clay Creek, Pennsylvania.

: David Funk using his shallow underwater photography rig.

: Special rig for taking pictures of living insects on stream bottoms.

: Epeorus pleuralis mayfly larva nestled among aquatic mosses in Rondout Creek, New York.

: Brachycentrus caddisfly larva in Neversink River, New York.

: Blepharicerid fly larvae crawling across the face of a waterfall in the Bear Kill, New York.

: Two Epeorus mayfly larvae in the Beaverkill River, New York. The upper specimen has recently molted.

: Tallaperla maria stonefly adult emerged from Spring Creek, Pennsylvania.

: Ephemerella dorothea mayfly, adult male emerged from White Clay Creek, Pennsylvania

: Eurylophella oviruptis mayfly, a recently-described species from swamp streams in North Carolina (female sub-adult).
