Spider too Close for Comfort

Spider too Close for Comfort

A number of years ago a gentleman told me about an orb weaver spider that was living by his front door. He said that it had been there for about two months and that it was interesting to watch the construction of the intricate “bug catching” web. However, he explained that he had a number of people coming to visit and he wanted to know about relocating the spider to his backyard.

These types of spiders typically construct their webs in an area and stay in that location based on the environment. Many of the orb weaver spiders rely on flying insects and usually construct their webs several feet or more above the ground. This is a good height to capture many flying insects. As a result, there needs to be items within a reasonable distance to attach and place the web. If a spider is randomly relocated, there may be nothing in reasonable distance to support a web. There needs to be at least a couple of tall shrubs or tree trunks for the spider to construct a web in-between the plants several feet above ground level. It needs to be in an area with limited people movement to prevent disturbance by people walking into it. It needs to be in a location with enough flying insect activity to satisfy the spider. If it’s not the right location, the spider may move back to another location, perhaps the front door area.

Webs built by these types of spiders can be quite large and may be suspended several feet or more above the ground. Some people become annoyed and/or frightened as they accidentally come in contact with these webs, brushing the webs from their face and arms. I’m sure the spider becomes annoyed, too, having to rebuild its web.

Despite their size, orb weaver spiders pose little threat to people. They’re considered beneficial because they feed on a wide range of flying insects. They usually construct webs in relatively sunny, open areas with little wind.

Even though these spiders are beneficial, many people don’t like spiders. If you choose to control spiders in and around your home, keep in mind it’s unwise and impractical, if not impossible, to control all spiders.

By the way, the gentleman concerned about the spider decided to leave the spider at the front door area. He posted a sign next to the web in hopes that his guests would steer clear of the web. He offered his garage entrance to those frightened by the spider.

Spiny Spiders

Spiny Spiders

The year’s mild winter and frequent rain showers have created lush lawns and gardens with an abundance of insects. As a result, we are seeing many predator arthropods taking advantage of the available feast.  One of the morning interesting creatures in the garden is the spiny orb weaver spider (Gasteracantha cancriformis) that has an interesting body shape.

Spiny orb weavers are common spiders in landscapes that might not be noticed since they are much smaller than the Yellow garden spider (Argiope aurantia) and the Golden silk spider (Nephila clavipes). Once viewed, the spiny orb weaver will catch your attention because it’s abdomen has six ‘spines’ or points that extend out.  Spiders also have a mix of yellow, white, red, or black marking on the abdomen.

Although spiders are small, the webs which are common amongst shrubs, trees, and edges of woods become quite substantial in the fall. There may be up to 30 spirals that extend out with the spider situated in the center.  You may unexpectedly encounter a web when walking through the garden or mowing around trees and shrubs.  There is no worry if a spider accidently gets on you as bites are not common and not considered serious.

Some may refer to the spiny orb weaver as a crab spider based on its shape, but it is a web building where the true crab spiders are active hunters often found resting on flowers in order to ambush a meal.

Enjoy our fall weather and look out for this beneficial spider in your landscape.
