Yellow sac spider

The yellow sac spiders (Cheiracanthium) are in the family Cheiracanthiidae and they probably account for more human bites that any other type of spider. These arachnids are distributed all over the globe, from America to Northern Europe, South Africa to India, and even Australia and Japan. They’re nocturnal predators and during the day they hide in small white web cocoons.

It is the only spider in Europe whose bite can penetrate human skin.

Trying to undo my fear of spiders by taking pictures of them and was very fond of this ceiling spider/yellow sac spider (Cheiracanthum inclusum) sheltering in the table flowers. Very common to find inside and has an unfounded reputation of incessantly biting humans and being incredibly dangerous (causing necrosis around the bite area) when in reality it doesn’t tend to bite humans anyways, and if it does the symptoms are mild and short lived. Being nocturnal, it usually spends the day in a silk sac before leaving, usually a ceiling corner or other infrequently disturbed spot, to hunt other creatures.
