Information: - A weevil is a type of beetle from the Curculionoidea superfamily. They are usually small, less than , and herbivorous. Over 60,000 species are in several families, mostly in the family Curculionidae (the true weevils). Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil ("Stegobium paniceum"), which belongs to the family Anobiidae. - Polyphaga is the largest and most diverse suborder of beetles ; the name is derived from two Greek words : poly - , meaning ' many ' , and phagein , meaning ' to eat ' , so the suborder is called the '' eaters of many things '' . Polyphaga comprises 144 families in 16 superfamilies , and displays an enormous variety of specialization and adaptation , with over 300,000 described species , or approximately 90 % of the beetle species so far discovered . Key characteristics of Polyphaga are that the hind coxa ( base of the leg ) , does not divide the first and second abdominal / ventral plates which are known as sternites . Also , the notopleural suture ( found under the pronotal shield ) is not present . - The abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The region occupied by the abdomen is termed the abdominal cavity. In arthropods it is the posterior tagma of the body; it follows the thorax or cephalothorax. The abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between L5 and S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. - Beetles are a group of insects that form the order Coleoptera. The word "coleoptera" is from the Greek , "koleos", meaning "sheath"; and , "pteron", meaning "wing", thus "sheathed wing", because most beetles have two pairs of wings, the front pair, the "elytra", being hardened and thickened into a shell-like protection for the rear pair and the beetle's abdomen. The order contains more species than any other order, constituting almost 25% of all known animal life-forms. About 40% of all described insect species are beetles (about 400,000 species), and new species are discovered frequently. The largest taxonomic family, the Curculionidae (the weevils or snout beetles), also belongs to this order. - The Curculionidae comprises the family of the "true" weevils (or "snout beetles"). It is one of the largest animal families, with 5,489 genera and 86,100 species described worldwide. - Insects (from Latin ', a calque of Greek ['], "cut into sections") are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. They are the most diverse group of animals on the planet, including more than a million described species and representing more than half of all known living organisms. The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing animal life forms on Earth. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, a habitat dominated by another arthropod group, crustaceans. - Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). The animal kingdom emerged as a basal clade within Apoikozoa as a sister of the choanoflagellates. Sponges are the most basal clade of animals. Animals are motile, meaning they can move spontaneously and independently at some point in their lives. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later in their lives. All animals are heterotrophs: they must ingest other organisms or their products for sustenance. What is the relationship between 'polyphaga' and 'coleoptera'?
