Illinois boasts a delightful variety of orb-weavers, the spidery architects famous for their elaborate webs. These glistening masterpieces are sure to impress...from a safe distance.

The Wanderers: On the Hunt

Not all spiders subscribe to the whole "web" thing. Jumping spiders (Salticidae), for instance, are the adventurous athletes of the spider world. These fuzzy little hunters have excellent vision and can leap surprising distances to snag their prey.

Spot a jumping spider? Admire their impressive hops from afar, but remember, even the cutest spiderbro can still give you a little bite if feels threatened.

Maybe It Came From Inside the House...

Let's be honest, some spiders find their way indoors. The most common house spider is the Yellow Sac Spider (Chiracanthium inclusum). These little yellow guys are fast-moving hunters, and their webs are more like silken sleeping bags than elaborate hunting grounds.

Sharing your home with a yellow sac spider? They're generally harmless, but if you're not a fan, catch-and-release (preferably outdoors) is always an option.
