Dubois writes, "seeing this strikingly colored bluet for the first time is a notable experience!" This common damselfly has been a nemesis odonate for me--I have been searching for it since I first started paying attention to these insects two years ago. Well worth the wait--what a tropical-looking species!
According to Montana Field Guide, larvae feed on various aquatic insects (like mosquito larvae) and adults cosume about any small flying insect they can capture, including "mosquitoes, flies, small moths, mayflies, and flying ants or termites." I found this male on Monday in tall grass along the large pond at St. Olaf College where Scott K. found them earlier during the day. The species is found from southern Saskatchewan, Montana and Colorado east into New England and southeastern Canada.
