Yellow garden spider
GigitanThe 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
Cara mengenalinya
- Yellow and black markings on the abdomen (the rear part of the body).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

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

Fakta
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
Pemecah mitos
Mitos: Yellow garden spiders are dangerous and their bite can seriously harm a healthy adult.
