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 spin webs several metres long, and their yellow threads look gold in sunlight.1

The name comes from a shape-shifting spider in Japanese folklore that can breathe fire and control other spiders.1

By October 2022, its range covered at least 120,000 km² across several US states.1

In the Ao-Naga people's food tradition, this spider is eaten.1

The spider was first spotted in North America in Hoschton, Georgia, in 2013, and its presence was confirmed in 2014.1

Smaller males are sometimes seen in the females' webs during autumn, when they mate.1
