The "baskettails" are a subgroup of emeralds named for the ball or "basket" of eggs the females carry on their abdomens. There are four species in Wisconsin and, with exception of the distinctive Prince Baskettail, the other three species are quite similar. Each has a dark abdomen with orange side-spots and thus their identification rests almost entirely on shape of the abdominal appendages. In Beaverpond Baskettail, the male's upper claspers are bent downward at the end with an upward spur and the female's appendages are stout and close together. They are fairly common in much of Wisconsin at a variety of wetland habitats, mostly in early-mid summer (June).
