In the south, we have an insect called the love bug, because usually in their short adult life, they are more than likely joined in a rather prolonged mating ritual. Fueled by a natural affinity for carbon monoxide, they are infamous for clogging radiators, splattering windshields, and generally making motorists miserable during their hatching season. Their favorite hangout is busy intersections and shopping center parking lots. But a number of them do wander onto the waterways, and most fish won't hesitate for a bug in basic black.
Hook: Mustad 94840 (standard dry fly) size 12 - 14
Tail: Black horse mane (or any rather stiff black hair)
Body: Black dubbing (the drier the better)
Wings: Crow wing slips
Hackle: Black dry fly hackle
Thread: Orange 6X
If you have ever tied a dry fly, this is no different. Set the foundation, cement, tie in tail (3 strands set for balance), wrap dubbing, tie in the wings, wrap the hackle, finish with a wrap knot and cement. No need to eleborate, other than balance is everything.
If you want to really do a number on the fish (and your friends), use a 4xl dry fly hook and tie this fly double, facing forwards and backwards, omitting the tail and doubling the hackle.
In fishing this fly, cast it to a likely spot and let it sit on the surface. Being terrestrial by nature, a love bug that lands on the water usually never rises again. Tiny twitches are suitable for drawing attention, but be careful not to overdo it. In moving water, standard dry fly tactics apply.
Don't let the inactivity of the presentation lull you into sleep. This is a popular fly with the fish. Don't fall asleep when the love bug bites.
