Coin Spiders (Herennia multipuncta, Nephilidae)

Herennia is a genus of spiders in the Nephilidae family with Australasian distribution. Spiders in this genus are sometimes called coin spiders.

These often large spiders can be easily overlooked on the trunks of trees where they make a circular flat web on which the female lays her eggs.

The much smaller males mutilate and sever their pedipalps, which are often found stuck in the female genital openings. It is suggested that they act as mating plugs to prevent other males from mating with the female and thereby ensure the paternity of offspring. The males cannot mate subsequently and these “eunuch” individuals continue to stay near the female.
