On the whole, I'm glad to see someone putting together a spider quiz because I love spiders. However, I do think that the quiz might need some revision. Some of these spiders have multiple names, for example, what you call the "black and yellow garden spider" is often just called a "garden spider" or even a "writing spider" because of the neat pattern of the web. It's also really odd that some spiders you're looking for the specific type, such as the golden orb spider (which is an orb weaver), and then you ask about a generic jumping spider, of which there are 1000s of species. Also, I thought it was odd that you required "cobalt blue tarantula" but I tried "cobalt" and also "cobalt tarantula" but neither of those took. It might also be neat to allow people to answer with the scientific name if they know it. Just some thoughts. Really fun to have a spider quiz though!
Great quiz
