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

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

Paano ito makikilala

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

Madalas mapagkamalang: 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

Mga kagat

Lumalabas ang kamandag sa pangil o ngipin nito kapag nangangagat ito.

Ano ang epekto ng kamandag nito?

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

Gaano ito kapanganib sa tao?

Panganib sa tao: MasakitTalagang masakit, pero halos hindi kailanman malala.

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

Kung kumagat ito

Hugasan ang kagat at lagyan ng ice pack para sa sakit. Kumuha ng tulong medikal kung matindi ang sakit, kumakalat, o masama ang pakiramdam ng tao.

Laging tawagan muna ang numero pang-emergency (112, 000, 911). Ito ay pangkalahatang gabay sa pangunang lunas, hindi payong medikal. Mga batayan ng pangunang lunas

Mag-ingat

Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
Kung kagatin ka ng isa: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.

Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat
