The guinea pig died within 7 minutes, leading to a belief that the spider's venom was dangerous. However, further research on anaesthetized guinea pigs showed that the original guinea pig had actually died of shock, rather than as a result of the spider's venom. [1] In humans the bite is no more dangerous than a bee sting. [4]
Araneus gemmoides, commonly known as the jewel spider (a name shared with Austracantha minax) and cat-faced spider (a name shared with Araneus gemma), is a common, outdoor, orb-weaver spider found in Canada and the USA. [1] It is considered harmless and has a low-toxicity venom. [2] A. gemmoides is a useful natural predator for insects. [1] [3] [4]
Palystes spiders are also commonly seen paralysed, being dragged by a large wasp called a pompilid or spider wasp. Sometimes, the wasp is not present. Pompilid wasps only hunt spiders, which they paralyse by stinging them. They then drag the spider back to their nest where they lay an egg on the spider, then seal the spider and the egg in.
“This is one of the few species of spider that can be dangerous to people,” says Potzler. “There are approximately 2,200 bites reported each year, but there has not been a death related to a ...
Spiders in the genus Palystes are commonly called rain spiders, or lizard-eating spiders. [3] P. castaneus often appears in the home just before the onset of rain, where they hunt geckos (usually Afrogecko porphyreus). Males are regularly seen from August to December, probably looking for females. [2] P. castaneus egg sac
Araneus gemma, commonly known as the cat-faced spider (a name shared with Araneus gemmoides) or jeweled orbweaver spider, is a common outdoor orb-weaver spider found in the western United States and Canada. Like most Araneus species, A. gemma is harmless to humans.
When the larva hatches, it consumes the spider, starting with the less vital parts to keep the spider alive for as long as possible, eating the vital organs last. Once finished consuming the prey, the larva pupates, and males usually emerge before females and patrol nest sites looking for newly emerged females with which to mate. [ 5 ]
The shamrock spider can be distinguished from other orb weaver species by the several white dots on its back. The legs of Araneus trifolium are usually brown or beige colored with several white bands around the joints. The shamrock spider creates a web to catch its prey. Small flying insects who fly into the web will get stuck in the sticky net.
