The white widow is a spider that is light-coloured, from beige to white, unlike most of its dark relatives. It lives in dry steppes and deserts across North Africa, the Middle East and central Asia. Its bite is venomous and can be medically significant, so it is worth knowing what it looks like.1

  • No bright red markings, unlike other widow spiders such as the black widow or redback spider1
  • Otherwise similar in shape to other spiders of the genus Latrodectus1

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

Its venom is neurotoxic in type, meaning it acts on the nerves, as is typical of Latrodectus species. Toxicology studies report that its venom is similar in structure to that of the Mediterranean black widow, L. tredecimguttatus. It is considered less toxic than the bites of L. mactans or L. hasselti.1

The bite is medically significant and can injure humans. It can kill children and people who are infirm, although it is not nearly as toxic as the bites of some other widow spiders. A poster by the Egyptian Society of Natural Toxins describes its venom as moderately venomous.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

Ukweli

1

Males are sometimes cannibalised by the female after mating.1

2

After maturity, male widow spiders do not feed and spend most of their lives searching for females, which is why they are smaller than females.1

3

Widow spider males generally live with a female for a long period and provide energy-demanding courtship displays.1

4

The white widow is comparatively rare compared to other widow spiders in its region.1
