• STAND ON THE WATER SURFACE UNTIL THE WINGS ARE DRY, THEN FLIES INTO NEARBY VEGATATION
• MALE & FEMALES FEED ON PLANT SUGARS• 24-72 HOURS THE FEMALE MATES.• AFTER MATING THE FEMALE LEAVES TO SEEK A BLOOD
MEAL.
• AFTER TAKING A BLOOD MEAL, THE FEMALE RETURNS & LAYS EGGS (100-300 EGGS).
• REPEATS BLOOD FEEDING & LAYING EGGS.• FEMALE MOSQUITO LAYS APPROXIMATELY 1000-3000 EGGS
IN HER LIFETIME.

• Larva prefer shallow, warm water• Larva are found in standing or slow moving water• Larva prefer water with organic material• Larva prefer living in close proximity to
vegetation, protected from waves
• Larva will dive when they feel vibration or water ripples
• Larva will dive if your shadow falls on the water• Larva use water tension to hold themselves at
the water surface to breath
• Anopheles larva can be found on top of algae
