Context: Endopterygota, also known as Holometabola, is a superorder of insects within the infraclass Neoptera that go through distinctive larval, pupal, and adult stages. They undergo a radical metamorphosis, with the larval and adult stages differing considerably in their structure and behaviour. This is called holometabolism, or complete metamorphism., 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., The ovipositor is an organ used by some animals for the laying of eggs. 
In insects an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as transmitting the egg, preparing a place for it, and placing it properly. In some insects the organ is used merely to attach the egg to some surface, but in many parasitic species (primarily in wasps and other Hymenoptera) it is a piercing organ as well., Holometabolism, also called complete metamorphism, is a form of insect development which includes four life stages  as an embryo or egg, a larva, a pupa and an imago or adult. Holometabolism is a synapomorphic trait of all insects in the superorder Endopterygota. In some species the holometabolous life cycle prevents larvae from competing with adults because they inhabit different ecological niches. Accordingly, their morphology can be adapted to just one phase of activity, such as larvae feeding for growth and development, as opposed to adults flying for dispersal and seeking new supplies of food for their offspring. In some insects, the adults can protect and feed the younger stages., A pupa (Latin "pupa" for doll, plural: "pupae" or "pupas") is the life stage of some insects undergoing transformation. The pupal stage is found only in holometabolous insects, those that undergo a complete metamorphosis, going through four life stages: embryo, larva, pupa and imago., A stinger, or sting, is a sharp organ found in various animals (typically arthropods) capable of injecting venom, usually by piercing the epidermis of another animal. , Biologically, an adult is a human being or other organism that has reached sexual maturity. In human context, the term "adult" additionally has meanings associated with social and legal concepts. In contrast to a "minor", a legal adult is a person who has attained the age of majority and is therefore regarded as independent, self-sufficient, and responsible.
Human adulthood encompasses psychological adult development. Definitions of adulthood are often inconsistent and contradictory; a person may be biologically an adult, and have adult behavior but still be treated as a child if they are under the legal age of majority. Conversely, one may legally be an adult but possess none of the maturity and responsibility that may define an
adult character., A wasp is any insect of the order Hymenoptera and suborder Apocrita that is neither a bee nor an ant. The Apocrita have a common evolutionary ancestor and form a clade; wasps as a group do not form a clade, but are paraphyletic with respect to bees and ants., A larva (plural "larvae" ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle., Hymenoptera is the third - largest order of insects , comprising the sawflies , wasps , bees , and ants . Over 150,000 species are recognized , with many more remaining to be described . The name refers to the wings of the insects , but the original derivation is ambiguous . All references agree that the derivation involves the Ancient Greek  ( pteron ) for wing . The Ancient Greek  ( hymen ) for membrane provides a plausible etymology for the term because these insects have membranous wings . However , a key characteristic of this order is that the hind wings are connected to the fore wings by a series of hooks . Thus , another plausible etymology involves Hymen , the Ancient Greek god of marriage , as these insects have `` married wings '' in flight . Females typically have a special ovipositor for inserting eggs into hosts or otherwise inaccessible places . The ovipositor is often modified into a stinger . The young develop through holometabolism ( complete metamorphosis ) -- that is , they have a worm - like larval stage and an inactive pupal stage before they mature ., An arthropod (from Greek "arthro-", joint + "podos", foot) is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and jointed appendages (paired appendages). Arthropods form the phylum Arthropoda, which includes the insects, arachnids, myriapods, and crustaceans. 
Arthropods are characterized by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. The rigid cuticle inhibits growth, so arthropods replace it periodically by moulting. Their versatility has enabled them to become the most species-rich members of all ecological guilds in most environments. They have over a million described species, making up more than 80% of all described living animal species, some of which, unlike most animals, are very successful in dry environments., 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., Venom is a form of toxin secreted by an animal for the purpose of causing harm to another. , Subject: hymenoptera, Relation: parent_taxon, Options: (A) animal (B) apocrita (C) arthropoda (D) endopterygota (E) human (F) hymenoptera (G) insects (H) metazoa (I) pupa (J) thorax
