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

Indlela yokusibona

  • 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

Ivamise ukudidaniswa ne: 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

Amandla obuthi

Ukuluma

Ubuthi buphuma ngamazinyo aso obuthi noma ngamazinyo uma siluma.

Ubuthi baso benzani?

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

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KubuhlunguKungaba buhlungu ngempela, kodwa cishe akukaze kube kubi kakhulu.

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

Uma siluma

  • Geza inxeba lokulunywa bese ubeka iphakethe leqhwa phezu kwalo ngenxa yobuhlungu. Thola usizo lwezokwelapha uma ubuhlungu bunamandla, busabalala noma umuntu ezizwa engaphilile.

Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala

Hlala uphephile

  • Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
  • Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
  • Uma sikuluma: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.

Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile
