Myrmarachne innermichelis BÖS. et STR., Micaria claripes DÖNITZ et STR., Phrurolithus komurai YAGINUMA (=Ferreria cibunea KISHIDA) have ant-like appearances. But Myrmarachne innermichelis does not attack the ant. Micaria claripes; this spider probably feeds on ants. I have made an experiment on this species in various methods, and found this spider attacks the ant (Lasius niger LINNAEUS) at night. The cocoon of this spider is attached to the underlying surface of a stone. Phrurolithus komurai is always found beneath the stone which lies on the nest of some red ant.
