The Common Spiders of Australia
Black house spider is one of the most common species of spider found across Australia and New Zealand. These spiders are better known as window spider because of the common nature of weaving web around the window corners. Although these spiders are less known for its toxicity, a bite from a black house spider can cause some irritation and illness including swelling of the bitten part and muscle pain. So it is always better to keep away from a spider, no matter which species they belong to.
These spiders mostly choose urban habitats and are mostly found on the rough parts of trees in the natural habitat. With the common nature of these spiders, they are found in plenty even inside the buildings and houses. Inside the buildings and houses, these spiders are found in and around the windows and doorways. There is a reason why these black house spiders select these places. These are the places that get the most light in the building and therefore many insects will be attracted towards this part. This makes it easy for these spiders to find and catch their prey. Overall, the feeding part is made easy by selecting the place to live.
Talking about the size of these spiders, there is a considerable difference in the size between that of male and female spiders. While a male black house spider can grow up to 9mm in size, a female grows up to double the size of male. These spiders are known to weave lace webs with a funnel shaped entrance. The black house spiders, like many other spider species, usually feed on flies, ants, mosquitoes, butterflies and bees. These spiders have a life span of about 2 years. People, when they spot a spider on the walls of their house, tend to kill them. But, spiders do play an important role in pest control.
