The Negev widow is a venomous spider that lives in the hot, dry deserts of the Negev and the Arava valley. It builds large webs in bushes and brush, where it hunts insects at night. Its bite can cause latrodectism, the illness caused by widow spider venom.1

During the day it hides from sight under the densely silk-lined nest area of its web, and it is mainly active at night.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

After mating, the male may escape being eaten by living in the nest with the female for a time, but in other cases the female eats him.1

Its web has separate areas for nesting and for catching prey, and it also helps keep the spider cool by providing shade in summer.1

Its webs often include a funnel of silk decorated with debris, which may help hide the spider from predators such as birds flying overhead.1

The web's silk carries pheromones that help males find female nests.1

Its colour darkens after each moult, so the spider becomes darker as it grows older.1
