The woodlouse spider is a small spider that hunts woodlice, the small grey creatures that curl up when touched. It lives in warm places under logs, stones and plant pots, and it is now found on almost every continent except Antarctica. It is a skilled hunter with large fangs, but it is not known to be a health risk to people.1

It is usually found under logs, rocks, bricks, plant pots and in leaf litter in warm places, often close to woodlice. It has also been found inside houses. During the day it rests in a silk retreat in crevices, usually in partly rotten wood, or in tent-like shelters in the hollows of large rocks.1

Què menja?

It mainly eats woodlice. It uses its large fangs to get past the tough outer shell and injects venom into the soft underside, avoiding the woodlouse's unpleasant defensive chemicals. It also eats silverfish, earwigs, millipedes, burying beetles, crickets and other spiders and centipedes.1

Com reconèixer-lo

Six eyes.1
A tawny orange to dark red head and chest section (cephalothorax) and legs.1
A shiny, pale beige to yellow-brown abdomen, which can be dark grey and sometimes very shiny.1
Very large fangs (chelicerae) for a spider of its size.1
Adult females are 11 to 15 mm long, and males are 9 to 10 mm long.1

Sovint es confon amb: The woodlouse spider can be hard to tell apart from Dysdera erythrina, which is much less common. D. erythrina is not usually found near human homes, so location can help.1

Si mossega

Renta la mossegada i posa-hi gel per al dolor. Busca ajuda mèdica si el dolor és fort, s'estén o la persona es troba malament.

Estigues segur

No toquis, atrapis ni molestis mai un animal salvatge, encara que sigui petit i encara que sembli adormit o mort.
Deixa-li espai. Si en trobes un, mantén la calma, recula a poc a poc i deixa que segueixi el seu camí.
Si te'n mossega un: mantén la calma, no et moguis, truca al número d'emergències (112, 000, 911) o ves de pressa a un hospital. Recorda com era, una foto ajuda.

No va a per tu. Fa servir el verí per caçar o per defensar-se, i prefereix mil vegades amagar-se. Més sobre com estar segur
