43 In cases like this, a bit of common sense biology can help. Mosquito larvae, for the most part, live right at the water’s surface, unlike odonate larvae which prowl on underwater plants and the bottoms of ponds and lakes. Thus, damselfly larvae may not encounter mosquito larvae as often as they encounter other sorts of food. As well, other sorts of mosquito control practices may inadvertently target damselflies. In fact, one Hawaiian damselfly species became seriously endangered when a primarily surface-feeding fish (Gambusia, the mosquitofish) was introduced for mosquito control and turned out to be a pretty good predator on damselfly larvae as well.

A number of his slides were used in this book, and I’m sure you’ll agree it’s easy to spot them at a glance—they are that good! As well, at the Wagner Natural Area, the summer student in 1995 was Natasha Klingsh (now Natasha Page), and Natasha decided to survey the odonates of this interesting peatland as part of her summer duties. Another undergraduate student, Christine Rice, undertook a similar survey at the Beaverhill Lake Bird Observatory in 1998. Christine is now working on 32 damselflies of alberta The first meeting of HOGSOC, the “Hyperboreal Odonatists’ Guild and Social Club,” with Carroll Perkins, Kamal Ghandi, John Acorn, Natasha Page, Carole Patterson, and Dena Stockburger.

Hunters think of our province as part of the “duck breeding factory” for North America, because most of the waterfowl on the continent breed in what many people call the “pothole lakes” of the Canadian prairies. Well, these same habitats are home to most of our damselflies. Overall, we have far fewer lakes here than in adjacent Saskatchewan or British Columbia, but still, Alberta is a wet enough place to support a respectable damselfly fauna. Damselflies in Alberta almost all prefer standing rather than flowing waters.
