When a covalently bonded molecule has more electrons in one area than another, it is called a polar molecule. The electron cloud model can show an unequal sharing of electrons. ... This shows that electrons are more attracted to the oxygen end of the molecule than the hydrogen end, making the water molecule polar.
Hymenoptera
: membrane wings/ typically two pairs of wings, some groups wingless (ants)/ hind wings smaller than front wings, linked together by small hooks (hamuli)/ wings have few cross-veins,
Blattodea
: insect avoiding light/ antennae slender, filiform/ pronotum oval, shield like, covering much of head and thorax/ legs adapted for running,
Coleopteran: hard wings/ front wings (elytra) are hard and serve as covers for the hing wings, meet in a line down the middle of the back/ hind wings large, membranous,
Odonata

: toothed flies/ antennae short and bristle-like/ compound eyes large often covering most of the head/ four membranous wings with many veins and cross veins/ base of hind wing broader than forewing,
Mosquitoes are insects belonging to the order Diptera, the true flies.
