The golden silk orb-weaver is a large spider with silk that shines golden in sunlight. It lives in forests and wooded areas from the southern United States to Argentina. It is special because its silk is studied by scientists, and because it is one of the largest non-tarantula spiders in North America.1

Jinsi ya kumtambua

Females have a silvery white front body (cephalothorax) and a longer orange-brown abdomen with two rows of small white-yellow spots.1
Females have dark yellow and brown banding on their legs, with black brush-like tufts of hair near the joints of the first, second and fourth leg pairs.1
Females are about 24 to 40 mm long when fully grown.1
Males are much smaller, about 6 mm long, with a plain dark brown body and legs.1
The large webs are circular and vertical, and the yellow pigment in the silk gives them a golden glow in good light.1

Mara nyingi huchanganywa na: Trichonephila plumipes also has stiff hairs on its legs. In that species the hairs are set more closely together than in the golden silk orb-weaver.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

Its silk may help in surgeries involving the nervous system, as shown in past experimental studies.1

It produces seven different types of silk, and its silk is valued in spider silk research.1

Its genome was the first of the orb-weaving spiders to be completely annotated, revealing 28 unique genes for spider silk proteins.1

Some individuals living in developed areas have grown significantly larger than their rural counterparts.1

Males rarely suffer sexual cannibalism or genital mutilation, unlike males of many related species, which makes it a focus of study into spider mating.1

Females are some of the largest non-tarantula spiders in North America, and may be the largest orb-weaver species native to the United States.1

Kuvunja dhana potofu

Dhana potofu: The golden silk orb-weaver is an aggressive spider that attacks people.

Ukweli: It is not known to be aggressive towards humans. It bites only in self-defence if it is touched.1
