Funnel Web Spiders in Arizona: 4 Fascinating Facts About The Specie

What is so unique about Funnel web spiders in Arizona? Have you ever thought about that? Then, this article about these critters is for you!

Funnel web spiders in Arizona, part of the Dipluridae family, are known for their unique funnel-shaped webs. These webs open wide at the mouth and narrow into a tube, where the spider hides.

They are positioned just above the ground; these horizontal sheetwebs are non-sticky but highly effective for hunting. The spider waits patiently inside the narrow funnel for an insect to walk across its web.

When it feels the vibrations of its prey, the spider rushes out, bites the insect, and injects it with venom. The immobilized insect is then dragged back into the funnel, where the spider can safely consume it.

These fascinating spiders are an essential part of Arizona’s diverse wildlife, helping to keep insect numbers in check and we’ll learn more about it in this article.
