The wetland giant wolf spider is a fairly small wolf spider found across the eastern United States, parts of Canada and Mexico. It hunts at night on the ground instead of building a web. Its bite is not medically significant to people.1

Kako ga prepoznati

The carapace (the hard upper shell of the front body) is brown, with a distinct yellow stripe running from the front eyes down the body.1
The underside of the abdomen has distinct black spots.1
It is around 17 mm long on average, which makes it one of the smaller wolf spiders.1
Males have yellow legs without distinct markings. Females have reddish brown legs without markings or bands.1
It does not make webs and is usually active at night.1

Često se miješa s: It is often mistaken for the nursery web spider (Pisaurina mira). The wetland giant wolf spider has a brown carapace with a distinct yellow stripe from the front eyes, and black spots on the underside of the abdomen. It is also similar to T. georgicola, but it has black spots that T. georgicola lacks, and its faint yellow stripes do not extend as far.1

Otrovna snaga

Ugrizi

Otrov izlazi kroz očnjake ili zube kad ugrize.

Što radi njegov otrov kad ugrize ili ubode?

Its bite injects venom. In people, the venom causes only minor pain and swelling.1

Koliko je opasno za ljude?

Opasnost za ljude: BlagoKao ubod pčele ili slabije. Uglavnom bezopasno za ljude.

It is not very aggressive and will not attack people unless provoked. Its bite is not medically significant to humans, and antivenom is rarely needed.1

Dobre vijesti: liječnici za ovo imaju lijek (protuotrov) ili liječenje.1

Što radi kad se uplaši?

It hides in burrows, under stones or boards, and relies on camouflage and speed to avoid predators. If needed, it will bite a predator and inject venom.1

Ako ugrize

Operi ugriz i stavi na njega vrećicu leda protiv boli. Potraži liječničku pomoć ako je bol jaka, širi se ili se osoba osjeća loše.

Uvijek prvo nazovi broj za hitne slučajeve (112, 000, 911). Ovo su opće upute za prvu pomoć, a ne liječnički savjet. Osnove prve pomoći

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ugrize: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice

Females can cannibalise males during or after mating. Smaller males are more likely to be eaten, and hungry females are more likely to do it.1

This species does not build webs. Females make silk-lined burrows under stones or boards instead.1

Males live for just over a year, while females often live for around two years.1

Hunger affects behaviour. Well-fed females made significantly more burrows than starved ones in a 1999 study.1

Females are much larger than males. Mature females weigh more than 300 mg and have carapaces about 6.5 mm wide, while males usually weigh more than 200 mg and have carapaces about 4.5 mm wide.1

Razbijač mitova

Mit: Wolf spider bites are dangerous and medically serious.

Istina: The bite injects venom, but it usually causes only minor pain and swelling. The spider is not very aggressive and will only bite when provoked.1
