The larva eat with a voracious appetite. As they grow they go through a series of molts until they are ready to emerge. At this point they go into a rest state for a day or two, called diapause, when the finally changes between aquatic and flight form take place. These photos are of a type of blue darner dragon. Unfortunately I was unable to get a good shot of the side stripes on the thorax and so I can not identify it. It was taken in the Minnesota Valley NWR in October.
