#3406 - Celaenia excavata - Common Bird-dropping Spider
A common orbweaver from many parts of Australia, but now naturalised in New Zealand as well. Despite being an orbweaver, they don't build webs - instead they produce a single strand of silk loaded with chemicals that mimic moth sex pheromones, and seize any hopeful males that show up. This is extremely effective, and their eggsacs are large and numerous because of all the food they get.

Also, they resemble a large blob of birdshit.
