Dot-Winged Baskettail, Epitheca petechialis

The dot-winged baskettail (Epitheca petechialis) is a species of dragonfly that can be found in the United States, with a range that includes Texas, Oklahoma, and Colorado. It can be seen later in the year than other baskettail dragonflies, typically between the months of January and July. The species is named for its spots, although not all individuals hold these spots, which occur on the hind wing. It is difficult to distinguish individuals with no spots from other baskettail dragonflies, but this can be done by examining the appendages found on the tip of the abdomen. These appendages, known as caudal appendages, differ between different dragonfly species.
