Phthirus pubis, the crab louse. Two females are apparent by the presence of a bifurcate posterior, whereas the male (topmost, slightly smaller specimen in the first and last picture) has a rounded posterior. Nice pictures!

Phtirus pubis or Pthirus inguinalis (preferred recent name), parasite of human pubis, also commonly known as crab louse or pubis louse.

Could I get them ? :-)) Sorry Bobbi but I do appreciate such crawlies but only between slide and coverslip !
One say this species is endangered because of pubis hair removal... right ?

Some nice photos on my blog with egg (baby inside)!

Cheers !

Arthur,
Thank you for your comments, you always give us a few points to ponder and we appreciate that very much. Dr. Pritt gives us such a great learning tool and to tell the truth, I truly enjoy the learning experience from everyone.

Phtirus pubis (crab louse). The latter louse is distinguished from the pediculus capitis and pediculus humanis by its smaller size (less than 2 mm). Its 2nd and 3rd pairs of legs are wider and more powerful than the first pair of leg.
