The lens fly ( Thyreophora cynophila ), also known as the dog fly , is a type of fly from the cheese fly family (Piophilidae). It was believed to be extinct for 160 years before it was rediscovered in late 2009 ( Lazarus taxon ).
description
The lens fly reaches a size of approx. 10 mm. The large swollen head is bright orange-red and phosphorescent. The body is metallic blue. The wings each show two dark points.
Way of life
The lentil fly lives in dark places and was often found on the carcasses of large domestic and farm animals such as dogs, mules and horses in autumn .
Distribution and Status
Central Europe , especially Germany , France , Switzerland and Austria was originally assumed to be the main distribution area. Fifty years after it was described by the German entomologist Georg Panzer in 1798, the species was last sighted near Paris. Their disappearance was believed to have been due to changes in livestock husbandry and carcass disposal during the Industrial Revolution . At the end of 2009 an amateur photographer discovered an unknown species of fly in the Spanish national park “Sierra de Cebollera”, which he initially thought to be a tropical species. In August 2010, a Spanish team found more specimens in the same national park and confirmed the rediscovery of the lens fly.
