Types of spiders in Grand Rapids, Michigan
They are known to vary in size where some grow up to 2 inches in length. Unlike house spiders, a Wolf spider is much bigger and is characterized by shades of brown. They are very active and agile hunters. Unlike other spiders that are commonly known to weave webs and wait for prey to be trapped by the web, a Wolf spider will chase and pounce on its prey. It preys on small insects like grasshoppers, crickets, ants and flies. This is because they are agile and quick which makes it difficult even for home owners to trap or squash them.
The female spider carries the large egg sac around and when they hatch, the hatchlings climb on their mother’s back which makes the spider to appear bigger.
Black and Yellow Argiope spider
Also known as the zipper spider, it is commonly identified by its strikingly colored abdomen which makes it attractive. As the most conspicuous species of orb weaving spiders, it is known to breed once in a year. The female Black and Yellow Argiope spider grows up to 1 1/8 inches while the males range in size from ¼ inch to 3/8 inch. Their abdomens are somewhat rounded and flattened while their legs are black with red or yellow bands on segments.
They spin circular webs which help to capture a wide range of flying prey for example flies, moths, beetles, wasps and mosquitoes among others. This spider is more active during the day since it has poor vision. It is generally harmless but the large webs it spins may be inconvenient to home owners.
They are similar to large Wolf spiders especially in size, shape and coloration. The reason they are called Fishing spiders is because they reside close to water where they have been reported to prey on small fishes and aquatic insects. The females measure between 15 to 25 mm while males measure between 7 to 13 mm in length. They are characterized by their alternating lighter brown markings, scalloped annulations on the femore and reddish brown or black annulations on the tibia. The Fishing spider is also known to reside under stones, loose barks, in tree cavities and homes. Although they do bite, the bite is not severe compared to a bee or wasp.
Common house spiders
Their bodies are divided into cephalothorax and the abdomen. Just like other spiders, they are wingless. They have eight legs so they are classified as arachnids and not insects. The common house spider is usually found in various places within a home for example windows, ceiling corners and above or below fixtures. They are known to form webs which are characterized by silken threads structures. The webs are not only a nuisance but they are used by spiders to capture flying prey for example flies and mosquitoes. Common house spiders may bite when defending themselves but the bites only result in small lesions and swelling.
