The yellow garden spider is a large, colourful spider with yellow and black markings on its abdomen. It builds big round webs in sunny fields, gardens and along the eaves of houses in North America, Mexico and Central America. It bites only if disturbed or handled, and its bite is comparable to a bee sting.1

Žije v

Contiguous United States, Hawaii, southern Canada, Mexico and Central America; found from Canada to Colombia, but less often in the basin and mountain areas of the Rockies.1

Domov

Yellow garden spiders build webs in open, sunny fields, where they stay concealed and sheltered from the wind. They are also found along the eaves of houses and outbuildings, and in any tall vegetation where a web can be stretched securely.1

Čo je?

The spider waits in the centre of its web for prey to become trapped. It may shake the web back and forth to trap the insect further, then kills the prey with venom and wraps it in a silk cocoon to eat later, typically 1–4 hours afterwards. Prey includes insects and small vertebrates such as geckos and green anoles.1

A mostly white front body section (cephalothorax).1
A large, circular web up to 60 cm across, with a dense zigzag of silk in the centre.1
The female sits in the centre of the web, usually facing straight down.1
Females measure 19–28 mm in body length, while males are much smaller at 5–9 mm.1

Sila jedu

Uhryznutia

Jed vychádza cez jedové zuby, keď hryzie.

Čo robí jeho jed?

The venom contains polyamine toxins, including one called argiotoxin ArgTX-636, which are being studied for possible medical uses. For most people the venom is harmless, and a bite causes redness and swelling, similar to a bee sting. It is harmless to people who are not allergic.1

Aké nebezpečné je pre ľudí?

Nebezpečenstvo pre ľudí: MierneAko včelie bodnutie alebo menej. Pre ľudí v podstate neškodné.

These spiders are not aggressive and only bite if grabbed or disturbed. For a healthy adult, a bite is not considered an issue. People who are very young, elderly, or have weakened immune systems should take the same care they would around a beehive or hornet nest.1

Čo robí, keď sa bojí?

If disturbed by a possible predator, the female may drop from her web and hide on the ground nearby, and she can shake the web vigorously while staying attached in the centre.1

Ak uhryzne

Umy miesto uhryznutia a daj naň ľadový obklad na bolesť. Vyhľadaj lekársku pomoc, ak je bolesť silná, šíri sa alebo sa postihnutý cíti zle.

Vždy najprv zavolaj na tiesňovú linku (112, 000, 911). Toto sú všeobecné rady prvej pomoci, nie lekárska rada. Základy prvej pomoci

Buď v bezpečí

Nikdy sa nedotýkaj divého zvieraťa, nechytaj ho ani ho nedráždi, aj keď je malé a aj keď vyzerá, že spí alebo je mŕtve.
Nechaj mu priestor. Ak nejaké stretneš, zostaň pokojný, pomaly cúvni a nechaj ho ísť svojou cestou.
Ak ťa uhryzne: zostaň pokojný, nehýb sa, zavolaj na tiesňovú linku (112, 000, 911) alebo sa rýchlo dostaň do nemocnice. Zapamätaj si, ako vyzeralo, fotka pomôže.

Nejde po tebe. Jed používa na chytanie potravy alebo na obranu a oveľa radšej sa schová. Viac o tom, ako zostať v bezpečí

dobré vedieť

Fakty

The female can shake her web vigorously to make it harder for wasps and birds to target her, and to fully tangle an insect before it cuts itself free.1

After mating, the male often dies and is sometimes eaten by the female, as he inserts his second palpal bulb.1

The zigzag silk in the web, called a stabilimentum, may camouflage the spider, attract prey, or warn birds away, but its purpose is still disputed.1

In a case observed in Georgia, a European hornet cut free prey caught in a yellow garden spider's web, and the spider did not fight it, probably because it dropped from the web and hid.1

Lovec mýtov

Mýtus: Yellow garden spiders are dangerous and their bite can seriously harm a healthy adult.

Pravda: The venom is harmless to people who are not allergic. A bite is comparable to a bumblebee sting and is not considered an issue for healthy adults.1
