To avoid any misunderstandings: this book is not about spiders as pets, but about those spiders that live in our houses and apartments as lodgers. Mostly ignored and sometimes (wrongly) feared, there is hardly a building in the world that does not harbour some species of spider. What is fascinating is that we always find the same species. These spiders must have special adaptations, because the humidity in our homes is far too low, they are too clean, and the food supply is usually scarce. However, those spiders that have made the leap into our four walls are rewarded with a worldwide right to stay. This, in turn, is due to people's eagerness to trade and migrate worldwide: Humans tirelessly transport their belongings and an endless stream of goods around the world in sacks, parcels and containers. And our domestic spiders, as stowaways, travel just as tirelessly and unrecognized. It is therefore possible to present domestic spiders found throughout the world in a single book, as they are essentially the same everywhere. The 50 or so most important species and species groups are presented here in a generally understandable way, with a detailed profile, photos and distribution maps.
The authors of this book are experts who work at museums, universities and in administration in Europe and North America. They are not only recognized scientists, but have also been avowed spider fans for decades.
