  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Hexapoda  \Hex*ap"o*da\,  n.  pl  [NL.,  fr  Gr  "e`x  six  +  -poda.] 
  (Zo["o]l.) 
  The  true,  or  six-legged,  insects;  insects  other  than 
  myriapods  and  arachnids. 
 
  Note:  The  Hexapoda  have  the  head,  thorax,  and  abdomen 
  differentiated,  and  are  mostly  winged.  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.  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. 
  See  {Insecta}.  The  Hexapoda  are  divided  into  several 
  orders 
 
  From  WordNet  r  1.6  [wn]:

  {Insecta},  {class  Insecta},  {Hexapoda},  {class  Hexapoda}]
