The red widow is a venomous spider that lives only in Florida, in the dry, sandy scrub where sand pine trees grow. It is a close relative of the black widow, but it rarely comes into contact with people, so it is not often met. Its bright red colours make it easy to recognise.1

Anaishi

Central and southern Florida, USA1

Amerika Kaskazini

Nyumbani

It lives mainly in sand-pine scrub, which is inland areas of dry sand dunes covered in sand pine trees. It builds most of its webs in palmetto bushes, at least 30 cm above the ground. It seldom comes into contact with humans.1

Urefu

4 cm (1.6 in)3

ukubwa wa kawaida wa mnyama mzima

Kasi ya juu

takriban km 0.98 kwa saa (maili 0.61 kwa saa)

Nchi kavu, makadirio

Hula nini?

It is a predator of the insect Hemisphaerota cyanea. It catches prey in its tangled webs, then retreats to a funnel-shaped hideaway below.1

Jinsi ya kumtambua

The cephalothorax (the front part of the body) is red-orange.1
The abdomen is black, with yellow rings outlining rows of red spots.1
The legs are vermilion red.1
The underside does not have the familiar hourglass marking. It usually has one or two small red marks instead.1
Females are almost double the size of males.1

Mara nyingi huchanganywa na: It is closely related to the black widow (Latrodectus mactans). The two can be told apart by features of the male and female genitalia, which are examined under magnification. The red widow's male embolus has one fewer loop, and the female's connecting ducts to the spermatheca also have one fewer loop.1

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

The red widow is venomous like other members of the genus Latrodectus. In a documented bite, the main effect was a mildly painful throbbing sensation that lasted several hours. The median lethal dose (LD50) of its venom in mice is 2.20 mg/kg, and each spider contains about 0.157 mg of venom.1

Ana hatari gani kwa watu?

Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.

No bites from this spider are recorded in the medical literature. It seldom comes into contact with humans, unlike the black and brown widows, which live close to people. One documented bite caused a mildly painful throbbing that lasted several hours.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
