Answer

Adults infested with P pubis are usually sexually active and have groin and body hair involvement. Involvement with pruritus of the groin, axillae, eyelashes, or eyebrows can help differentiate P pubis infestation from head or body louse infestation. Parents of children infested with P pubis on the eyelids and/or eyebrows should be questioned about also being infested because the parents are usually the source of infestation.
