World Mosquito Day
Yes there really is a day for the little blighters that can make the summer's here a little difficult.
World Mosquito Day, observed annually on 20th August is a commemoration of British doctor Sir Ronald Ross's discovery in 1897 that female mosquitoes transmit malaria between humans. Ross is responsible for the annual observance, having declared shortly after his discovery that the day should be known as World Mosquito Day in the future.
The London School of Hygiene & Tropical Medicine holds Mosquito Day celebrations every year, including events such as parties and exhibitions, a tradition dating back to as early as the 1930s. (Thanks Wikipedia)
I shall be celebrating by getting bitten (I'm sure), and maybe being murderous and dispatching some info the great unknown.
