and adults inhabit freshwater wetlands, specifically wet heaths and acid swamps; although juveniles are predominantly found in terrestrial vegetation surrounding wetland areas. Adults are dark brown with a conspicuous white, cream or yellow stripe along both sides of their abdomen and thorax.
302:(Greek translation= crafty or wily), the raft spider typically hunts on the surface of the water with its front appendages outstretched and relies on aquatic vibrations to detect prey. Juveniles are thought mainly to hunt in terrestrial vegetation. Their diet consists largely of freshwater

Juveniles are similar in appearance but often have green translucent legs. As is common in other spiders, female raft spiders (body length: 9–22mm) are usually larger than males (body length (9-15mm). Dolomedes fimbriatus was described in chapter 5 of the book

is sexually cannibalistic, meaning that the female will sometimes eat the male before, during or immediately after mating. Males will try to court the female and prevent her from attacking by signalling their presence using vibrations on the female

If successful copulation takes place, the female will carry her fertilised egg sac around with her, before placing the egg sac inside a silken nursery tent that she has made. The female will then guard the nursery until the
