These are often seen in groups flying around low to the ground. When they stop long enough to observe they always seem to be males, as indicated by the long antennae. (Compare the antennae of the female on the next page.) Females, who may not have a yellow spot, have been seen only rarely. The next page may show a female feeding on nectar but the males have never been seen doing this.
