with a huge egg sac.
I found some information about the Nursery Web Spider from the British Arachnological Society's webpage as follows:
A female carries her large eggs sac beneath her body, held in the jaws. Prior to the spiderlings hatching she fixes it to some plants and spins a silken tent around it and then stands guard. It is the distinctive tents that give her away. She guards the eggs and spiderlings, giving rise to the English name of Nursery Web Spider.
I have submitted our record to the BAS as the distribution maps showed the species has not been recorded on Islay before. It is, however, a fairly widely distributed species, suggesting that, as with many other genera, it is under-recorded, rather than rare!
Thanks everyone for your enthusiastic contributions today.
