Hello everyone,
I have a problem telling if some of my specimens are Bombylius discolor or B.medius. Mark van Veen in his online key (http://home.hccne...ylius.html) says that those species are separated by color of body ventral hair - black in discolor, yellow in medius. 'Keys to European Part of the USSR' say that end of the abdomen of discolor is black whilst in medius it is yellow or almost white. Are there any other charecters used, or color is just enough?
