PUPA - MOSQUITOES

• Commonly called the "tumblers" due to the tumbling movement they exhibit
• Aquatic, comma shaped
• The head and the thorax are fused together to form the Cephalothorax
• Below this is the flexed abdomen
• On the dorsal aspect of the head a pair of  breathing trumpets are seen
• The 9^th abdominal segment shows the presence of a pair of paddles which enable the pupa to move
• The life cycle is usually completed in a weeks time-it may be prolonged under adverse conditions
