False Wolf Spiders
Zoropsis spinimana, also known as False Wolf Spiders, are reasonably large, Mediterranean spiders have been turning up in people's homes in and around London, since 2013. Two have been found in Sussex - the first in 2014, in East Grinstead, and more recently, a gravid female was found in a kitchen in Brighton, in 2017. I acquired this beautiful spider, and observed her building her egg sac, of which I was unaware if it was to be fertile or not.

Fertile egg sac
The egg sac did turn out to be fertile, and I managed to capture 26 babies, that I found wandering around my flat. I have been rearing these babies, on fruit flies, bean weevils, and hatchling locusts. These spiderlings, are now stunning little versions of their mother.
How to keep
They actively hunt down prey, and are extremely fast, when they need to be. Zoropsis spinimana are not web builders, they tend to rest vertically, so keep them in a semi-arboreal set-up. No need for a heat mat, as long as they are kept in a warm room.

Should you provide water?
I did not observe the mother drink water, but I would provide a small, shallow dish of water, otherwise, a dry habitat, as they are used to dry conditions, living in our homes.
I am sure that one day, these spiders will be commonplace in the UK. They are synanthropic / associated with human habitat, and they are rather conspicuous, so they will be easy to spot.
