Negev widow
KuumwaThe 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
Jinsi ya kumtambua
- Females are very dark brown. Pregnant females are light brown with a pale golden hue.1
- Males are brown with a patterned abdomen in various shades of brown, and may have grey-white spots and stripes on the abdomen.1
- Females measure 9 to 19 mm long. Males measure 3 to 7 mm long.1
- The web has a funnel of tightly woven silk near the top of the bush, often decorated with debris such as bits of plant, sand, rocks and snail shells.1
Nguvu ya sumu
Sumu hutoka kupitia meno yake ya sumu au meno anapouma.
Sumu yake hufanya nini?
Its venom is the widow type and can cause latrodectism, which is the illness caused by bites from widow spiders. It has been reported that its venom is about as potent as that of Latrodectus tredecimguttatus.1
Ana hatari gani kwa watu?
Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.Hufanya nini akiogopa?
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
Akiuma
- Osha jeraha na uweke barafu kupunguza maumivu. Tafuta msaada wa kitabibu kama maumivu ni makali, yanasambaa au mtu anajisikia vibaya.
Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza
Kaa salama
- Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
- Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
- Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.
Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ana kasi gani?
Ukweli
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
