The baskettail species that occur in Wisconsin are very similar to each other, requiring in-hand examination to be sure about species identification. They differ primarily in the shape of the terminal appendages and presence or absence of dark markings on the wings. They are medium-sized dragonflies with dark brown bodies and small yellow markings on the sides of the abdomen. There is some disagreement among odonatists as to whether they should be placed in the genus Epitheca or the genus Tetragoneuria. In the latter case, the prince baskettail would be placed in the genus Epicordulia.
This large brownish dragonfly has distinctive markings on the wings. It is the largest emerald, the body length varying from 2.3 to 3.1 inches. Due to its markings on the wings, it may be confused with the twelve-spotted skimmer, except it has no white on its wings. Their mating and egg-laying habits are like other Epitheca species.
Common throughout eastern United States and southeastern Canada, this species is found at permanent ponds, lakes, slow streams, and rivers. It is commonly found throughout Wisconsin.
Early June to mid-September in Wisconsin.
