Case of the Week 313

The following case was generously donated by Florida Fan.  These images were all obtained from specimens submitted from a 5-year old girl who was possibly the daughter of a migrant farmer.  Identification?  Bonus:  name the forms!

    Wonderfully apt! I'm currently in Utah at the International Conference of Phthirapterists! We've had a lot of talks about these little guys. Pediculus humanus capitis. At least given the age of the patient I hope they're head lice and not body lice!
