The eggs are laid on the surface of water in areas of heavy emergent vegetation. After hatching, the small larvae attach themselves with the modified siphon to the roots or submerged stems of plants where they remain throughout development. The pupa also attaches itself to plants by means of the modified respiratory trumpets and remains there until the adult is ready to emerge. The females bite principally at night, apparently being most active during the early part of the night. They occasionally attack man during daylight hours in shady places when their haunts are invaded. (Carpenter and LaCasse 1955:110)

Medical Importance
