dysdera crocata silk ring

[caladina]

one of my dysdera crocata spiders has made its home / resting place between the back of a peice of tree bark and the vivarium tank glass,
what its done is to make a ring of silk between the two sealing its self in
the diameter of the silk is the length of its own size, so its literally layed it down as its turned around

the distance between the glass and wood is just a couple of mm, enough for a cosy fit

any idea what its purpose is, its been there for a cuple of days, preggy or just snoozing?

Is it male or female?
They are nocturnal and generally hide during the day, sometimes just under things and other times they create a silken cell.
The female also creates a silken cell when she want to lay her eggs.

Photos please.

its moved now, think a meal worm disturbed it
as i'm not a dysdera crocata myself, how would i tell the sex of them?

Males will have 'boxing gloves' on, enlarged areas at the end of the palp, for Dysdera sp they fold underneath and are quite simple.
Females have plain palps, and generally larger abdomens.
To see her epigastic fold (this group of spiders have no epigyne (- the opening for the female sex organ)) you'd have to look underneath of her abdomen.

So you keep spiders but don't know that much about them?! Time for some reading I think
