Buzzers / Chironomidae are midge pupa; they start life as a bloodworm living in the soft mud found in most still waters. Blood red worms get their colour from the oxygen and haemoglobin held within their bodies. When they are getting near to hatching they loose their blood red colour and take on a more sombre appearance. At this stage they then make their way from the lake bottom up through the water columns to the surface. They swim towards the surface in an wriggling action, stopping either to catch their breath or waiting for the right conditions to hatch. When they stop wriggling towards the surface they slowly sink back down before swimming upwards again. Eventually when they reach the surface, they hang from the surface film and hatch out in to adult buzzers or midge.
