Politicians aren't the only creepy creatures having a good season: Warm weather has made for "perfect conditions" for a bloom of spiders around Sydney, Australia, reports the Australian Museum.
A warm summer down under has led to a boom in various arthropod species, from flies to moths, and that abundance of prey has meant many more spiders are surviving to adulthood than during leaner years. Some spider moms even produced two and three sets of offspring this year.
Giant webs can be seen streaking across the landscape.
Redbacks, huntsmen, golden orbs, and St. Andrews Cross spiders are said to be particularly prevalent.
These kinds of boom and bust cycles are pretty common in nature, says Louis Sorkin, an arachnologist with the American
"The warm weather generally around the world accounts for good numbers of arthropods," says Sorkin. "Unfortunately, many people associate them with pest species in their (human) environment."
In other words, many people don't like having spiders in their homes. But they shouldn't be afraid, says Sorkin, because spiders perform critical ecosystem services, by keeping pesky prey like mosquitoes and flies in check and recycling nutrients.
Although some spiders do have venom strong enough to be dangerous to people, bites from them are quite rare. The animals tend to be much more scared of us than we should be of them. Most of the world's 40,000 or so species of spiders are relatively harmless.
In the rare case that you are bitten, try to trap the spider so you have it for identification. You can place it in the refrigerator to slow it down and make it easier to transfer to another container. Usually all you need to reduce the pain is an ice pack, but seek medical attention if you experience more serious symptoms such as severe pain, nausea, vomiting, spasms, or dilated pupils.
