Hi Frits!
I am surprised about the coincidence - since I found a Tegenaria cf campestris male in a park here in Sofia, I searched through all Tegenaria species and encountered this one in Wiki, remembering it has only photos of preparates - and here you are with your post!
I have some questions as well: could you give habitat type, size, and number of moults it needed to reach maturity with intervals between (it would be interesting to know how fast they develop, at which time of year they mature - unless you examined it soon after its ast moult)? I guess it didn' t differ in lifestyle from other Tegenaria species.
