Western Forktail

On 18 June 2020, I found this male Western Forktail in a flood control pond about a mile from our home. Only three forktail species inhabit Olympia. These damselflies are relatively easy to tell apart. I was, however, concerned about the blue sides to this ode’s thorax—this color should be green. Dennis Paulson explained to me that the blue indicates that this individual is probably a young male whose sides will become green. This small species is fairly common across much of western North America. Males are less often encountered than are females. Sometimes at ponds no males are observed. Females only need to be fertilized once in their lives, and can store the males’ sperm for future use (Paulson 2009).
