| | HEXAPODA - LoveToKnow Article on HEXAPODA |
 | | Escherich (1901), after a new research on the embryology of the muscid Diptera, claims that the fore and hind endodermal rudiments arise from the blastoderm by invagination, and are from their origin distinct from the mesoderm. | | | And thus perfection of structure and instinct in the imago has been accompanied by degradation in the larva, and by an increase in the extent of transformation and in the degree of reconstruction before and during the pupal stage. | | | On the whole it seems likely that the endoder1n is represented in part by the yolk, and,in part by those anterior and posterior rudiments which usually form the mesenteron, but that in some Hexapoda the whole digestive tract may be ectodermal. |

| | Checklist of the Collembola: Are Collembola terrestrial Crustacea? |
| | The monophyly of Hexapoda is provisionally accepted as a basic assumption by Bitsch and Bitsch, 1998:341,356 (based on Boudreaux, 1979; Kristensen, 1991, 1995, 1997; Bourgoin, 1996; Deutsch, 1997). | | | The abscence of an antagonistic muscle to the depressor of the last podomere in Hexapoda, Chilopoda and Diplopoda has been considered as a common autapomorphy. | | | Collembola are difficult to position due to the discrepant results of morphological and molecular phylogenies; they are probably key taxa to explain arthropod relationships (Giberet and Ribera, 2000:225). |

| | ,Pocock, indeed, definitely associated the Chilopoda with the Hexapoda in a group, the Opisthogoneata (Opisthogonea), equivalent to a group, the Progoneata (Prosogonea), comprising the Diplopoda, Pauropoda and Symphyla. | | | Moreover, the recent researches of Heymons into the embryology of Scolopendra, one of the Chilopods, has shown a close correspondence in the number of cephalic metameres between the Chilopoda and Hexapoda, a correspondence which has not yet been established in the case of the Diplopoda or Symphyla. | | | As the basis for this classification was taken,the position of the generative orifices which open in the Opisthogonea at the posterior end and in the Prosogonea near the anterior end of the body. |

| | Hexapoda - Wikipedia, the free encyclopedia |
| | The term, hexapoda, alludes to having "six feet", the most distinctive feature of the group: a consolidated thorax with three pairs of legs. | | | The subphylum Hexapoda constitutes the largest (in terms of number of species) grouping of arthropods and includes the insects as well as a few much smaller groups of wingless arthropods closely related to insects: Collembola, Protura, and Diplura. |

| | The Tetraconata embrace the hexapods as well as entomostracan and malacostracan crustaceans and their name refers to the tetrapartite crystalline cone in the ommatidia as a synapomorphy of these three groups. | | | Instead, these studies advocate an independent conquest of land by Hexapoda, Chilopoda, and Progoneata. | | | Morphological and palaeontological evidence now shed doubt on an important synapomorphy of the Hexapoda and “Myriapoda” in the Tracheata hypothesis, namely the monophyletic origin of tracheae. |

| | They have three pairs of mouth organs, viz., mandibles, maxill[ae], and the second maxill[ae] or labial palpi; three pairs of thoracic legs; and abdominal legs, which are present only in some of the lowest forms, and in the larval state of some of the higher ones. | | | [1913 Webster] Note: The Hexapoda have the head, thorax, and abdomen differentiated, and are mostly winged. | | | Many (the Metabola) undergo a complete metamorphosis, having larv[ae] (known as maggots, grubs, caterpillars) very unlike the adult, and pass through a quiescent pupa state in which no food is taken; others (the Hemimetabola) have larv[ae] much like the adult, expert in lacking wings, and an active pupa, in which rudimentary wings appear. |

| | In some academic traditions the term 'entomology' only refers to insects (in a broad sense, i.e., = Hexapoda), but often the study of the other 'terrestrial' arthropods, i.e., myriapods and arachnids, is - as here - is considered part of 'entomology'. | | | The RB arthropod classification, which recognizes three main groupings of extant taxa: Chelicerata, Crustacea and 'Uniramia' (comprising Onychophora, myriapods and Hexapoda) is rooted in the 'Mantonian' view. | | | Crustacea and Hexapoda may be sister groups, or the latter subordinate in the former. |
