Bibio marci – There have been quite a few of these large dark flies recently out and about. The male is depicted in the top image, and the female below, which shows obvious differences between the sexes. They appear around April 25th, St Mark’s Day, hence the name. They are quite slow and lazy fliers. Double-click images to enlarge.
