Aug 16, 2017: Dragonflies and Damselflies




The last interpretive talk of the season, "The Odonates of Ada Hayden Heritage Park", was presented by Erv Klaas and Wolf Oesterreich to 9 participants.  Erv (in photograph) started off by talking about damselflies and dragonflies from prehistoric times (fossils) to today.  He also discussed reproductive strategies and differences between the two types.  Photographs of some of the common species were shown, as well as field guides that we use.  Afterwards, Wolf led the group on a short walk along the north shore.  At least 8 species were discovered, with 2♂ and 1♀ American Rubyspots being the best find. (Wolf. Oesterreich, 8/16/17)
