Whiteflies are small insects, about 2mm. As an adult has triangular white wings, and covered by a dusty wax.
Whiteflies make laying eggs on the underside of the leaf
It is a very important and difficult pest to control as attacks plants weakening the sheet, her wounds made for penetration into the plant, land on the lower leaf surface by a pedicle which is attached to the substrate. So there is less availability of nutrients for the plant, development and retention falling leaves.
This insect is so small that is easily confused, apply other insecticides that are not appropriate.

Some species of whitefly form long filaments which make females put
The egg deposited by the fly of this species and fertilized on the same sheet by the male lasts about nine days after larva becomes grouped in a circle around the blade. When it reaches the form of pupa, it has legs but no wings, is when they expand around as the wind or shower object, etc. You can reposition it to another plant. In the state of adult males are you dedicated to hover around the plant and female looking for new places to put their future.
Adult flies always hovering around the eggs
