Answer the following question: Information:  - In dipterous insects, halteres (singular halter or haltere) are minute dumbbell-shaped organs that have been modified from hindwings to provide a means of encoding body rotations during flight. Halteres are rapidly oscillated simultaneously with the wings, allowing them to experience forces resulting from body rotations. If the body of the insect rotates about one of its three axes (yaw, pitch or roll), the rotation exerts a force on the vibrating halteres  this is known as the Coriolis effect (see below). The insect detects this force with sensory organs called campaniform sensilla and chordotonal organs located at the base of the halteres and uses this information to interpret and correct its position in space. Halteres act as a balance and guidance system by providing rapid feedback to the wing-steering muscles, as well as those responsible for stabilizing the head. This is what allows flies to perform their fast acrobatic maneuvers.  - The Streblidae are flies in the superfamily Hippoboscoidea, and together with their relatives the Nycteribiidae, are known as bat flies. They are winged or wingless ectoparasites of bats, and often have long legs. They appear to be host-specific, with different species of bat flies occurring only on particular species of bat hosts, sometimes with multiple species of flies sharing a host bat.  - 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.  - Nycteribiidae of the true fly superfamily Hippoboscoidea are known as `` bat flies '' , together with their close relatives the Streblidae . As the latter do not seem to be a monophyletic group , it is conceivable to unite all bat flies in a single family . They are flattened , spiderlike flies without eyes or wings , and are seldom encountered by general collectors , as they almost never leave the bodies of their hosts . Both males and females take blood meals , thus they qualify as real parasites . Most species are highly host - specific . The family is primarily found in the Old World tropics ; a few of the 274 known species occur in the Neotropics and in Europe .  - Hippoboscoidea is a superfamily of the Calyptratae. The flies in this superfamily are blood-feeding obligate parasites of their hosts. Four families are often placed here:  - True flies are insects of the order Diptera, the name being derived from the Greek "di" = two, and "ptera" = wings. Insects of this order use only a single pair of wings to fly, the hindwings being reduced to club-like balancing organs known as halteres. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described.  - Bats are mammals of the order Chiroptera (from the - "cheir", "hand" and - "pteron", "wing") whose forelimbs form webbed wings, making them the only mammals naturally capable of true and sustained flight. By contrast, other mammals said to fly, such as flying squirrels, gliding possums, and colugos, can only glide for short distances. Bats do not flap their entire forelimbs, as birds do, but instead flap their spread-out digits, which are very long and covered with a thin membrane or patagium.  - Calyptratae is a subsection of Schizophora in the insect order Diptera, commonly referred to as the calyptrate muscoids (or simply calyptrates). It consists of those flies which possess a calypter that covers the halteres, among which are some of the most familiar of all flies, such as the house fly.    Given the information, choose the subject and object entities that have the relation of 'parent taxon'.
