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.
