|Thunder Lake in the North Cascades.|
Dragonflies were flying everywhere along the shoreline. Just as we got there I saw a large dragonfly do two splash-dunks in the open water, followed by a spin-dry. It may have been a Blue-eyed Darner, which was seen several times at this location.
Surprisingly, though, the most common dragonfly was the Chalk-fronted Corporal. This is a dragonfly we've seen only once before in the North Cascades area, but at Thunder Lake they were present in numbers. The Corporal is named for the two light-colored bars on the front surface of the thorax, which are reminiscent of a corporal insignia in the military. Here's are a couple Chalk-fronted Corporals from Thunder Lake.

Another dragonfly that stood out at Thunder Lake was the Hudsonian Whiteface. It does indeed have a white face, as its name suggests. In fact, when it flies toward you its face flashes in the sunlight. The Hudsonian also has a series of brilliant red spots along the abdomen, similar to those seen in the Calico Pennant in Virginia. Here's one that perched fairly close to us.

We also saw a dragonfly larva at Thunder Lake. I don't get to see them that often, so it was a good opportunity for a photo.

We saw 11 species at Thunder Lake. Here's the species list:
