Why Are Spider Plant Leaves Turning Black Or Dark Brown?
Spider plants are among the most popular houseplants. They have been used for centuries as decorative objects and they still remain popular today. There are many different kinds of spiders that inhabit our homes, but only some species produce webs to catch their prey. Some types of spiders produce silk while others do not. Silk is made up of protein fibers and it helps spiders stay attached to each other when they are moving around. Other than keeping them together, silk provides additional protection from predators and helps keep the web strong.
There are several types of spiders that make webs, but none produce silk like the black widow spider (Latrodectus hesperus). These spiders don’t spin webs very large or long; however, they do create webs that are quite noticeable. These webs are usually found in corners of rooms and closets. When a spider enters your home through one of these entrances, she will likely leave behind her web.
If you look closely at the edges of the web, you may see small holes where the spider entered or exited through. These holes are called “entryways.”
Black Widow Web Entrance Hole
The entrance hole can be anywhere on the outside surface of the web. It helps the spider move around the web. The spider hangs on to the web with her hind legs, then it “shimmies” side to side until it reaches a new location. The spider’s silk is sticky, so any insects that might accidentally bump into its web will get stuck.
Once prey is trapped in the web, the black widow will come over and bite it several times.
