Hey gang, I've been paying more attention to the presence of dragonflies and damselflies lately. I'm especially interested in correlating the presence of these insects to water sources. Dragonflys are not as reliable water-indicators as damselflies, merely because they can fly much farther and do migrate. If you see a damselfly however, you are probably pretty darn close to water. It occurred to me that collectively, using the power of the forum, a great database of dragonfly/damselfly occurrence in ABDSP could be constructed. I am volunteering to build a database and create GIS maps to share with the forum or any other interested researchers. Dragonflies and damselflies are rare enough where simply recording a GPS location (or approximate location, but the more precision, the better) would not be too onerous, I think. Heck, we could even add bees to the database if desired! All it would take is this: you see a dragonfly or damselfly in the park and record the location, plus any other bonus info you feel is important (whether it was specifically a dragonfly vs damselfly, color, flight direction, date, time of day, weather). Post your information to this topic and I'll slowly harvest the data and create some maps that all can enjoy. We'll probably learn things we never considered before. Photo below shows a damselfly on top, dragonfly below. - Jim
