mosquito net

a mosquito can fly (and bite)
but it cannot walk crawl or jump
which means the only way in which
a mosquito can move from place to place
is by flying. which means without spreading its
wings a mosquito cannot move.

true or false ?

if this is true why are we making mosquito nets
with such small holes ? why cant we make the mesh
larger which will allow more air flow and
consume less material ?

think of the saving in cost and enhancement in comfort.

is it not good business sense to research the idea ?
if it is enough to block the (large) wings then
why waste on arrangements to block the (small) body ?
