Hi there,
Having discovered this rather aggressive and energetic spider in my shed, I thought I'd spread the word, especially as a result of recent media coverage regarding bites.
I submitted the details to "Wild about Britain" who confirmed my sighting and suggested that I mention it here, as there seem to be no other sightings actually in Taunton, so far.

So I hope it's of interest to someone - even if not to my wife, who won't now venture into my shed - hurray!
