Probably, everyone in the life at least once saw a house spider. Average citizens know a little about these insects – they have eight legs, spin a web and eat flies. But whether so it? In apartments of spiders it is possible to meet quite often, even in the winter, and here population of flies gravitates to seasonality. So what the house spider eats?
What it is necessary to know about these spiders?
The Latin name of a species of this spider – Tegenaria domestica. In spite of the fact that he is called "brownie", it is possible to see it not only in dark corners of apartments, but also in closets and sheds on all globe. Practically are not afraid of this spider, he – rather everyday occurrence in our houses in addition its poison is not dangerous to the person though he bites, and is quite sick.
Features of the dwelling and hunting of a house spider
It will be useful to learn where usually there lives this spider. As his house serves the special web tube which conducts from network to a shelter. Of course, these spiders spin a web, but it differs a little from that which is spun by his street relatives. Its web thicker and more friable, and "street spiders" spin a thin viscous web with sticky small knots. Thus, its future food in a friable web literally sinks and, of course, tries to get out of the captivity. Attempts to get out of a web are noticed by a spider. Its web almost flat, however its center sharply goes down at a small angle, forming that inhabited web tube in which the spider waits for signals from the victim. As soon as the victim begins attempts to get out of a web, it quickly runs out from the shelter and snatches on it, sticking kryuchkovidny jaws. In them there is a poison which strikes the victim to death. However the spider cannot eat the died victim – at him the small mouth, chewing jaws (employees for mastication of food) are also absent. Therefore the spider should exhaust nutrients from the victim thanks to what the body under the influence of poison begins to digest itself.
Thus it destroys such mean insects as flies, front sights drosophilas, larvae of wood lice or moths. Generally, it makes a feasible contribution in fight of the person against mean insects. However not always the spider manages to eat the production. For example, if to him the ant is snared, then he, most likely, will survive – the house spider is not able to swaddle production, and poison has on large ants rather weak effect. One more feature of food of house spiders is the lack of need to spin big network – a part of individuals, especially male, is capable to manage several alarm threads, however they need the bigger "operating" area on which will fix the network.
