This Halloween — Show Spiders Some Love

This Halloween, we’re featuring spiders on the blog! But not to scare you. In fact, we thought Halloween would be the perfect opportunity to shed some (not-so-spooky) light on these creepy crawlies.

Our eight-legged friends (yes – you read that right) top the list of the most misunderstood helpers and are labeled as pests. Entomologists are working hard to change the public’s perception of spiders through education and outreach. After all, we are less likely to be afraid of something that we are familiar with and spiders have an important ecological role as the top invertebrate predator.

Living fossils

Spiders evolved 380 million years ago (long before the dinosaurs) and are believed to be the first animals to live on land. They are living fossils that evolved from an underwater ancestor that makes them closer cousins to a horseshoe crab than an insect.

Spiders are often lumped together with insects even though they are very different creatures. Spiders are in the same phylum (Arthropods) as insects, because they have a segmented body. To put that in perspective, humans are in the same phylum (Chordata) as hagfish, and obviously, other than a hollow nerve cord, we are nothing like a hagfish. The differences are that big!

Without spiders, we would be waist deep in other insects!! Spiders eat an astronomical amount of bugs – somewhere in the range of 880 million tons of bugs a year!

Fear and loathing 

You can Google hundreds of news articles about car wrecks and house fires caused by people’s fear of spiders. Just a few days ago, there was a house fire in California where a man burnt down his parent’s house trying to kill a black widow. While there is research that shows some people are born with an innate fear of spiders, other people raise them as pets. Read more
