Entomology (Study of Bugs)/Dragonfly


What kind of dragonfly is this? It was on a wooden support beam that holds up a wooden deck to a friend's house while out by the Lake the other day. Yellow and dark gray or dark silver in color. Everybody loved this guy. I've seen dragonflies but this one really stands out in color.

Dear Doug - This dragonfly appears to be a female in the family Gomphidae. If it did not move much from the place where you took this image, it may have emerged from its nymphal shell rather recently, which could help explain its relatively pale coloration. See http://tinyurl.com/j37kaox for an example of a mature specimen.
Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
