Horned Clubtail

This female Horned Clubtail is another of this summer's dragonflies that I encountered in June alongside the small pond at the southern end of Carleton College's lower arboretum. This species ranges across the northern, midwestern North America, usually near ponds, lakes, and marshes.  According to Ecobirder, Horned Clubtails appear early in the summer and are gone by the end of July. Adults will consume just about any small, soft-bodied, flying insect they encounter (Montana Field Guides).
