Found only on the islands of Oahu, Molokai, Maui, and Hawaii, the happy face spider, such as this one guarding its eggs on a leaf in Maui, is known for the unique patterns that decorate its pale abdomen. Scientists believe Theridion grallatormay have developed its distinctive markings to discourage birds from eating it.
