Where Are American House Spiders Found: A Comprehensive Guide
Have you ever wondered where these common house spiders are found in the United States? In this article, we will explore the habitats and distribution patterns of Parasteatoda tepidariorum, also recognized as the common house spider, in America.
Introduction to American House Spiders
Parasteatoda tepidariorum, the common house spider, is a species of house spider widely distributed across the Americas and other parts of the world. This spider is known for its adaptability to urban and human-dominated environments, making it one of the most common species of spiders found indoors in North America.
Geographical Distribution and Introduction
According to the World Spider Catalog, the common house spider has a complex distribution consisting of its native range in Asia and its introduced populations in North America, South America, and various other continents. It has been documented in every state of the United States, making it a widespread urban resident.
Habitats and Behavior
Common house spiders are typically found in and around manmade structures, where they create their characteristic cobwebs in various strategic locations. These cobwebs are most commonly found in corners, on walls, windows, curtains, and other areas where they can catch flying insects.
Their behavior is indicative of their synanthropic nature, meaning they are dependent on human activity and infrastructure. They often choose hiding spots in crevices and near the ceiling, making it easier for them to pounce on passing prey. Interestingly, when they venture down from their webs, they may become an easy target for curious cats, which enjoy playing with them.
Environment and Adaptability
These spiders are highly adaptable to a wide range of climates and conditions. They can be found in both indoor and outdoor settings, but their preference is usually for locations that offer shelter and easy access to food. Indoors, they often set up webs in dark corners where they are least likely to be disturbed.
