Water boatmen and backswimmers usually provide best fishing during early
spring and fall mating and migration flights. I once had a good day during
such a flight and what a day. A water boarman flight followed by little
caenis mayfies and then by midges. On that day the trout wanted the
boatman right on the top - I can't remeber the exact name of the pattern
but it used a closed cell foam body cut to shape, the back was painted and
marked with pantone then coated with aquaseal. Legs were from superfloss.

Here's a good site:
