The silver-spider drags its victim inbell, then lies on the back, secreting enzymes to digest soft tissue extraction. Serebryanka feeds on fish fry, insect larvae and crayfish with pleasure, in most cases hunting at night. Without losing a minute, the spider immediately runs to check whether the victim is caught. Like all representatives of arachnids, the silver from its cocoon stretches the signal threads to the nearest plants, driftwood and stones, so he immediately feels that someone has touched his web. So that the hairs on the abdomen do not stick together and capture as much air as possible, the silver from time to time combes them and lubricates with a fat secret, secreted from the mouth.Īlthough the spider is silver and has 8 eyes, he seesvery badly, but he has a sufficiently developed perception of concussion and movement. Having collected air into the lungs and hair, he plunges into the water to his bell, in order to dump air reserves there. At this point the silver woman is completely defenseless, so she tries not to attract attention.
Only the abdomen protrudes to the surface, the rest of the body is in the water. By the way, it floats pretty fast, with a speed of about 2 cm / s. To replenish the air reserves, the spider riseson the water surface. The spider breathes not only light, but also all surface, therefore air in a cocoon is spared sparingly. His house spider-silverstone fixes for a snag, plant or stone. Subsequently, it takes the form of a bell. First he weaves a reticulum, which then fills with air. The spider lives under the water and builds a house there. Most silverbirds are found on the territoryEurope in fresh standing waters with grassy vegetation. The description is very similar to other spiders, but there is something special about it - it's a huge amount of hairs on the abdomen, lubricated with waterproof material, they help the silver woman to breathe under the water, as they keep the air. The length of the body is from 1.2 to 1.5 cm, 8 feet, abdomen, cephalothorax, two pairs of jaws and 8 eyes - this is how the silverback spider looks. Most arachnids live on land, the same species is an exception.

Your contributions will help us learn much more about this species. iNaturalist is a free online community platform for reporting flora and fauna sightings. If you see a Joro spider, please report it to the iNaturalist project “ Orb weaving spiders in the Southeastern USA”. We do not recommend using fire (due to safety reasons) as a management tactic. Pesticides will kill individual spiders, but if you kill one, more are likely to move into that area. If Joro spiders are a nuisance and somewhere they need to be removed, simply use a stick to move the web and spider to another location. It is unlikely to be dangerous to humans or pets other than being a nuisance in some situations. Males are much smaller, drab brown in color, and can often be seen in the webs along with the females.īecause the Joro spider is not native to the United States, we do not know what kind of impact it will have on native fauna. Webs and spiders will get progressively larger until about September, when the large adult females are very noticeable due to their bright coloration. Juvenile Joro spiders can be seen beginning in early May, making webs on practically anything: homes, decks, porches, landscape plants, and natural areas. Joro spiders overwinter as eggs, which hatch in late spring.
Adult female Joro spiders can sometimes reach 3 inches across! Despite their large size, there have been no reports of any bites, and DRC has frequently held them without any issues.ĭr.
