Eggs that are laid on or in water generally are not resistant
to BLANK and hatch shortly after embryonation,
provided that they are wet and not too cold

MOSQUITOES
Mosquito larvae are not buoyant and must, at rest, be
suspended at the surface by BLANK that cling to the surface tension while obtaining
oxygen directly from the air.

MOSQUITOES
pupae normally remain BLANK at the
water surface with the tips of their thoracic air trumpets in

MOSQUITOES
BLANK starts soon after emergence, usually
before females begin responding to host stimuli

Blood-feeding by female mosquitoes rarely begins until
at least DAYS TO DAYS after adult emergence, and often not until
after mating and sugar-feeding
