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 jo prepoznaš

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

Pogosto zamenjujejo z: 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

Moč strupa

Ugrizi

Strup pride ven skozi strupnike ali zobe, ko ugrizne.

Kaj naredi njen strup, ko ugrizne ali piči?

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

Kako nevarna je za ljudi?

Nevarnost za ljudi: BlagaKot čebelji pik ali manj. Za ljudi praktično neškodljiva.

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

Dobra novica: zdravniki imajo za to zdravilo (protistrup) ali zdravljenje.1

Kaj naredi, ko se prestraši?

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

Če ugrizne

Ugriz umij in nanj daj ledeni obkladek proti bolečini. Poišči zdravniško pomoč, če je bolečina močna, se širi ali se poškodovanec slabo počuti.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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

Mit: Wolf spider bites are dangerous and medically serious.

Resnica: 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
