Liberiblattinidae Explained

Liberiblattinidae is an extinct family of cockroaches known from the Jurassic to Cretaceous. Some taxa, like Cryptoblatta and Hydrokhoohydra, are suggested to be semiaquatic. Spongistoma is suggested to be a nectarivore due to its unique sucking/sponging "proboscis" mouthparts.^[1] Some authors have suggested that the family is ancestral to Mantodea.^[2]
