Dictyna arundinacea

Dictyna arundinacea is a small cribellate spider in the family Dictynidae. Carl Linnaeus described it in 1758, and it is the type species of the genus Dictyna.

The species has a Holarctic range and is widespread in Britain and northern Europe. Holarctic means it occurs across much of the Northern Hemisphere's North American and Eurasian regions.

Adults are about 2 to 3.5 millimeters long. Because it is so small, its tangled cribellate web and habitat can be more useful for identification than size alone.

It builds tangled mesh-like webs rather than the large circular webs associated with orb-weaving spiders. The species is a cribellate spider, a group known for producing a distinctive woolly capture silk.
