Phytophaga is a clade of beetles within the infraorder Cucujiformia consisting of the superfamilies Chrysomeloidea and Curculionoidea that are distinctive in the plant-feeding habit combined with the tarsi being pseudotetramerous or cryptopentamerous, where the fourth tarsal segment is typically greatly reduced or hidden by the third tarsal segment. The Cucujoidea are a sister to the Phytophaga.[1][2] In some older literature the term Phytophaga was applied only to the Chrysomeloidea.

| Phytophaga phylogeny |
The diversification of species within the Phytophaga is thought to be associated with the speciation within the Angiosperms. The plant-feeding habit may have been a shift from microfungal, spore-feeding (on strobili and cycads) and saprotrophic habits.[3] With nearly 125,000 described species they are the second largest phytophagous lineage of insects after the order Lepidoptera.[4] GH45s are only encoded by the genomes possessed by the Phytophaga beetles. The derived G45s from Phytophaga degrade 3 main substances: amorphous cellulose, xyloglucan and glucomannan. It was also composed of fungal sequences, acquired by gene transfer from fungi.[5]
