Filmy Dome Spider, male and female (Neriene radiate) — As you can see from this mating pair of filmy dome spiders, the males are much smaller than the females. These spiders build a domed web and hang upside-down under it, waiting for prey. And as you can also see in the photo, she’s been a successful hunter.
