Cellar Spider

There are three species of Cellar Spider in the UK but 2 are rare and only 1 is common. The (Common) Cellar Spider, also called Daddy Longlegs but the latter is also a name for a crane fly and even harvestmen, is a common web-building spider in outhouses, cellars and even homes. It is a long-bodied spider with very long, thin legs.

Head and body length of females is 8mm but legspan can be 7cm. They are known to prey on other spiders, even their own kind, as well as insects and woodlice. While that can be beneficial, their extensive mesh of webs is not.
