Theridion grallator, also known as the Hawaiian happy-face spider, is a spider in the family Theridiidae that resides on the Hawaiian Islands. T. grallator obtains its vernacular name of "Hawaiian happy-face spider" from the unique patterns superimposed on its abdomen, specifically those that resemble a human smiling face. Its Hawaiian name is nananana makakiʻi. The specific epithet grallator is Latin for "stilt walker", a reference to the species' long, spindly legs. T. grallator is particularly notable because of its wide range of polymorphisms that may be studied to allow a better understanding of evolutionary mechanisms. In addition to the variety of color polymorphisms present in T. grallator, this spider also demonstrates the interesting quality of diet-induced color change, in which its appearance temporarily changes as it metabolizes various food items.
