One of the largest species is the common Linyphia triangularis (above) whose webs hang in numbers from bushes in gardens and become very evident when covered in dew.
Neriene montana, is another large species (4-7 mm) common in gardens.
Gosammer and ballooning
These spiders can be incredibly numerous and active, and their drag silk threads can give fields a silvery shine, which is called gosammer. Money spiders disperse by ballooning. They climb up bushes and release a long silk line, which can get caught in the wind. Standing on tiptoes, the spiders are pulled up and lifted into the air.

Linyphia has some interesting mating tactics I have blogged about before. Males have large chelicerae they use to fight other males while they guard a female.

Money spider heads
Some money spiders have very unusual heads, with some of their eyes on top of turrets or humps (see if you can make sense of Walckenaeria!). These harbour glands that produce secretions, possibly nuptial gifts, during mating. Females of some species are known to hold the male's head during mating.
