Different kinds of spiders weave different kinds of webs. Observing the web will not be possible in all cases, as not all spiders leave their egg sacs in their webs. However, if you can’t tell what kind of spider you’re dealing with just by looking at the egg sac, then it is a good idea to check out the web. Common spider web patterns include:  Orbs. Circular patterned webs. Cobwebs or tangle. Messy looking fluffy webs that often appear in the corners of ceilings. Funnels. Webs in the shape of a tunnel that are located in low-traffic areas. Sheet webs. Flat sheet-like or bowl shaped webs. Wooly webs. Slightly sticky webs with an indistinct shape. Spiders make their homes in all sorts of places. You might find a web in a hole in a brick wall, the corner of a room, a tree, or a pile of dead leaves. Considering the location of a web will help you narrow down the possibilities for what type of spider’s eggs you are looking at. For example, tarantulas often live in burrows in the ground with a thin web covering the opening, disc web spiders often make their small grey webs on tree bark and brick walls, and comb footed spiders often make their webs in houseplants. Because many types of spider egg sacs look similar, it can be difficult to identify one without seeing the spider that left it. Some spiders lay their eggs and then depart, in which case you won’t see them around, but a number of them will stay close and protect the eggs until they hatch. If you do find the spider that made the egg sac you are trying to identify, getting a good look at the spider is your best chance at getting an accurate identification. Spiders come in many different colors and patterns. Some, like the distinctive Black and Yellow Garden Spider, are immediately recognizable, while others are more common looking.  Try to notice the details. For example, if the spider is brown, what shade of brown is it? Does it have any other markings? Is it the same shade of brown over her entire body? All spiders are covered with small hairs, but this...
