The bolas spiders in Japan

August 19,2000. M.Sekine

This is my newest spider. By chance, I found it in a meadow in Nabari City in Mie Prefecture, Central Japan. This species, Ordgarius sexspinosus, is known as the Bolas Spider.

Bolas spiders

I had been reading about how the Bolas Spider throws out a strand of silk with a sticky ball on the end to catch its prey, and how spider emits components of the moth-prey species' sex pheromones, imitating a chemical. It's a very interesting spider to study. I observed the spider for two weeks. But unfortunately, my spider didn't emit her bolas at all. So I released it to its habitat, where it belongs.
