Hexapoda    
六足纲

六足纲

Hexapoda
n 1: insects; about five-sixths of all known animal species
[synonym: {Insecta}, {class Insecta}, {Hexapoda}, {class
Hexapoda}]

Hexapoda \Hex*ap"o*da\, n. pl. [NL., fr. Gr. "e`x six -poda.]
(Zool.)
The true, or six-legged, insects; insects other than
myriapods and arachnids.
[1913 Webster]

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.
[1913 Webster]
