Pogosto zamenjujejo z: The black widow is slightly larger and darker, and has a red hourglass on the underside. The brown widow is lighter, has an orange or yellow hourglass, and has a black and white pattern on top of the abdomen that the black widow does not have. In southern Africa, the brown widow's relative L. rhodesiensis, native to Zimbabwe, is also called a brown button spider.1

Kaj naredi njen strup, ko ugrizne ali piči?

Like all widow spiders, the brown widow has a neurotoxic venom, which attacks the nerves. It causes latrodectism, a set of very unpleasant symptoms. The effects are usually confined to the bite area and the tissue around it.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: BolečeLahko zelo boli, a skoraj nikoli ni resno.

Brown widow bites are usually not very dangerous, and are much less dangerous than black widow bites. The spider cannot deliver as much venom as a black widow, so its bites are considered minor. They are painful.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

In Southern California, researchers suggest the brown widow may be pushing black widows out of the area by competing and fighting for territory.1

Its egg sacs are so spiky that they are easy to tell apart from those of most other spiders.1

A female can make up to 20 egg sacs over her lifetime, with 120 to 150 eggs in each.1

Brown widows are preyed upon by wasps, including blue mud-dauber wasps and digger wasps.1

Razbijalec mitov

Mit: The brown widow is as dangerous as the black widow.

Resnica: Brown widow bites are usually not very dangerous and are much less dangerous than black widow bites.1
