Eggs

Eggs are laid by female spiders inside a silk sac in autumn.

Spiderlings

After overwintering, the spiderlings hatch during spring and start creating webs for themselves.

The Web

Female spiders make webs hanging from vertical stems. Inside the webs, on either side, there could be some ‘bowers’ or ‘retreats’ located 1 meter off the ground. The spiders usually sit in the middle but connected with the web through a single strand when they hide in their retreats. In this way, they would sense any insects’ presence through vibrations.
These webs are built every morning and then eaten the following day by the spiders before making another one.
