The happy faced spider (Theridion grallator)

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 grallator may
have developed its distinctive markings to
discourage birds from eating it.
