Amaurobius similis, Lace Web Spider

Common Name: Lace Web Spider

Amaurobius similis, a lace web spider, measures up to 12 mm for the female, male to 8 mm. This spider probably occurs in almost every house and outhouse in the country. The spider makes its characteristic web of bluish cribellate silk in cracks in the brickwork, under the eaves, under undisturbed rubble or debris and between cracks in wooden sheds and fences, etc.

It is also occasionally found under bark in more natural habitats like woods especially where these are near habitation. It is often found that A. fenestralis replaces A.similis in these situations. Adults occur throughout the year but both sexes peak in the autumn, and females are recorded again in numbers during the spring and early summer.

https://www.uknature.co.uk is a website dedicated to showing the immense diversity of UK nature and wildlife. Our vast range of habitats, from lowland arable to snow covered mountains, from storm-ravaged coastlines to peaceful inland freshwater lakes and rivers, from dry, sandy heaths to deciduous and coniferous forests, all these habitats contribute to the abundance of UK nature. We have wild birds in huge numbers either residing or visiting our shores (597 recorded species as at July 2013) and we must also not forget the humble back garden with its grass lawns, flower beds filled with nectar rich flowers, shrubs and trees, all designed to attract huge numbers of insects such as bees, moths, butterflies and hoverflies; and finally the small ponds which provide safe havens for frogs, toads, newts and even slow worms and grass snakes. www.uknature.co.uk is the showcase for my personal passion, photographing uknature in all its glory. I sincerely hope you all enjoy the fruits of my labours.
