Caliscelidae
Piglet Bugs
Caliscelidae is a family of planthoppers in the superfamily Fulgoroidea, recognized as a distinct family based on 2013 molecular phylogenetic studies that separated it from Issidae. Members are small sap-sucking insects with marked sexual dimorphism in some species. The family includes approximately 250 described species across three subfamilies: Caliscelinae, Ommatidiotinae, and Peltonotellini. Some genera exhibit unusual morphological specializations, including ant-mimicking males in Formiscurra and the distinctive ball-shaped rostrum in Fitchiella robertsonii.
