Red-sided sector spider

The red-sided sector spider spins a round web with a funny gap in it. Two slices of the web are missing, like a pizza with two pieces gone. Through the gap runs one special thread that leads to its hiding place.

Fun fact: spiders are not insects. Insects have six legs, spiders have eight. Everyone calls them bugs anyway!
