TOPSHAM — Cathance River Education Alliance presents “Dragonflies of the Cathance Preserve at the Topsham Public Library from 6:30 to 8 p.m. on Tuesday, Aug. 28.

David Reed started photographing dragonflies at a park in Minnesota and some photos, such as the Horned Clubtail ended up in Dennis Paulson’s “Princeton Field Guide (Dragonflies and Damselflies of the West).” Many of his insect photos are featured on BugGuide and the Moth Photographer’s Group.

Reed has documented more than 600 local species of moths just by turning on his porch light at night. “I got seriously involved in nature photography when I retired in 2002 from a 20-year career in the veterinary biologics industry. My interest in photography started when I was a kid with an uncle who gave me a spare lens from a telescope he had made. This led to making a pin-hole camera and then borrowing my folk’s Brownie camera. Black and white photography was a necessary part of my career in microbiology where I needed to document bugs much smaller than the ones I now photograph,” Reed said in a news release.

This presentation is part of a year-long series of monthly community programs at TPL that occur every last Tuesday evening of the month. These community programs are free, family-friendly, and open to the public. They are designed to support CREA’s mission of “Connecting our Community to Nature.”
