Ero leonina
Ero leonina is a pirate spider in the family Mimetidae, a group known for specializing in preying on other spiders. It occurs in North America, with records from the United States and Canada. Like other mimetids, it is presumed to invade the webs of other spiders and subdue them, though specific behavioral details for this species remain poorly documented.
Pholcus phalangioides
Long-bodied Cellar Spider, Cosmopolitan Cellar Spider, Daddy Long-legs Spider
Pholcus phalangioides is a long-legged cellar spider native to Asia that has become cosmopolitan through human association. Females reach about 7-8 mm body length with legs 5-6 times longer; males are slightly smaller at 6-10 mm. The species is notable for building loose, irregular webs in dark indoor spaces and for its specialized predatory behaviors including web invasion and aggressive mimicry. It preys on other spiders—including dangerous species such as redbacks—and exhibits a distinctive whirling defense against predators. Despite common misconceptions, its bite is harmless to humans.
