Which family, the brush footed butterflies, has reduced forelegs and forelegs bearing brush-like hairs?

Explanation:
The trait being tested is the forelegs themselves. In this family, the front pair of legs is reduced in size and often covered with dense, brush-like hairs, so they’re not used for walking. This gives the impression that the butterfly has only four legs for locomotion, which is why these butterflies are called brush-footed. The brush-like forelegs are a distinctive feature of this group, setting them apart from other families whose forelegs are fully developed and used for grasping or walking.
