Leg charaters ■ the form of the tibial spurs and the tarsal claws The presence or absence of spines on the legs ■ Occasionally the structure of the epiphysis The epiphysis is a movable pad or spurlike structure on the inner surface of the front tibia; it is probably used in cleaning the antennae. The front legs are very much reduced in some of the butterflies

The wing venation the wing venation in this order is relatively simple because there are few cross veins and rarely extra branches of the longitudinal veins,and the venation is reduced in some groups
