The raft spider is a large spider that lives partly in the water. It is found across north-western and central Europe, mostly in wet heaths and swampy places. It is one of only two Dolomedes spiders found in Europe.1

Tuis

Adults live in freshwater wetlands, especially wet heaths and acid swamps. Juveniles are mostly found in the plants on land around wetland areas.1

Wat eet dit?

It eats freshwater invertebrates such as water beetles, pond striders and dragonfly larvae. It hunts on the water surface and detects prey through vibrations in the water. Occasionally it eats small vertebrates such as sticklebacks and small frogs.1

Hoe om dit te herken

Adults are dark brown with a white, cream or yellow stripe along both sides of the abdomen and thorax.1
Juveniles look similar but often have green translucent legs.1
Females are usually larger than males.1
Hunts on the surface of the water with its front legs outstretched.1

Word dikwels verwar met: The only other Dolomedes spider in Europe is Dolomedes plantarius, which is slightly larger. It is endangered in the UK.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

Wat doen dit as dit bang is?

To escape birds, it can fully submerge itself in water and has been known to hide underwater for several minutes.1

As dit byt

Was die byt en sit 'n yspak daarop vir die pyn. Kry mediese hulp as die pyn erg is, versprei of die persoon sleg voel.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

This spider is one of the few species known to attack nearly almost all approaching males, which biologists consider unusual because it can stop mating from succeeding.1

The raft spider can stay hidden underwater for several minutes.1

Females will sometimes eat the male before, during or immediately after mating.1

Males signal their presence to the female by using vibrations on her dragline, which may help them avoid being attacked.1
