Friday Fly Day - Flyday the 13th

In the theme of today (scary / spooky etc et al) we thought we'd try and identify our most terrifying fly in the range, one that strikes fear into the hearts of fish around the globe, a fly so horrific that you get a fright each and everytime you open your fly box. Turns out we don't really have one so we'll just show you this Booby instead. Booby, ha.
