Libellulidae Dragonfly AdultLibellulidae Dragonfly Adult View 3 PicturesThis specimen of Libella saturata, the flame skimmer dragonfly, is the only invertebrate in this site's collection that I caught by hook and line. It swooped down and attacked my dry fly on the Firehole River, where it lived as a nymph in the hot water near the geothermal springs and geyser runoff.

Brachycentrus americanus (American Grannom) Caddisfly LarvaBrachycentrus americanus (American Grannom) Caddisfly Larva View 13 PicturesBoth the genus ID (Merritt & Cummins) and species ID (Flint 1984) are pretty confident for this larva, a nice example of a common western caddisfly. It was by far the most abundant insect in my kicknet sample on this trip, and many of the rocks in the fast riffle where I sampled had dozens of these larvae clinging on.
