Plexippus petersi is a species of
jumping spider native to Asia and has been introduced to Africa and the
Pacific Islands. The male is between 6 and 10 millimetres (0.24 and 0.39 in) in length, and the female around 10 millimetres (0.39 in).
Plexippus petersi is a house spider, living indoors, and is noted for the skilful way it hunts and catches mosquitoes, flies and other invertebrates. It has also been found living in crops in the Philippines, in one instance in a rice field infested with the armyworm
Spodoptera mauritia, and in another, in a corn field attacked by the northern armyworm
Mythimna separata. This
focus-stacked photograph depicts a
P. petersi spider, approximately 7 millimetres (0.28 in) in length, on a human finger.
