Hawthorn Fly (Bibio marci, Linn.).
Bibio marci is commonly called the Hawthorn-fly, and was described under this name by Ronalds. It is, speaking broadly, first cousin to the Black Gnat, though it is very much larger. It appears at the end of April or the beginning of May. The body is black, and the wings show the oval patch in the B. johannis; but as the fly is larger, in the B. marci it is more noticeable. As only the male seems to rove about to any extent, it is just as well to imitate the male only.
Body. Black Berlin wool, ribbed with silver tinsel.
Hackle. Black.
Wings. (Male) Transparent part of quill feather of starling.
Hook. No. 1—3, new size.
An illustration of the natural fly is given on [Plate I.], and one of the imitations on [Plate II].
