The idea behind Luna Mayfly

How did the Luna Mayfly come about?

This particular fly is a product of a lot of experimenting and a need for a shortcut, to make a fun and easy foam body, followed by weeks of finetuning. Originally I was inspired by a caterpillar larva tied with a whole foam tube on top of the hookshank. 

Pay attention to the little details in the steps below. Don`t rush it, take your time, especially with your first attempt.

Step by step guide

Before I Tie The Luna Mayfly

This fly is the product of a series of experiments, a need to take shortcuts, and a longer period of refining the result.

Paying attention to the small details pays off when you’re tying the Luna Mayfly, but it’s a great addition to your fly box and, moreover, enjoyable to tie.

Follow every step in a detailed 18 step, step-by-step guide with picture illustrations and easy-to-understand language.

Are you ready to tie a Luna Mayfly?

Keep reading below to find all the information you need to tie this effective fly.

Luna Mayfly Guide - Step 1

Place the hook in the vise. I use a long-shank dry fly hook from the Japanese brand Maruto: d21. Cover the hook shank with tying thread, and tie in 3 Moosehair strands as tails. The tail strands should be approximately 2½ cm long.

- Michael Olesen

Luna Mayfly Guide - Step 2

Cut the foam cylinder in half lengthwise. I use a long-bladed pair of scissors.

- Michael Olesen

Luna Mayfly Guide - Step 3

Make a slanting cut of 3 mm on the round side of the foam. The foam piece will show this slanted cut.

- Michael Olesen

Luna Mayfly Guide - Step 4

Tie in the foam piece at the slanted cut, with the round side against the hook shank, right above where the tails are tied in. It’s crucial to fold the foam down over the sides of the hook shank. Take a couple of wraps with the tying thread and leave it 2mm in front of the foam just tied to the hook shank.

- Michael Olesen

Luna Mayfly Guide - Step 5

Fold the foam forward, stretch it slightly, and use the nail of your thumb to compress the foam around the hook shank. Make 3 wraps with your tyingthread, to create the first segment of the abdomen.

- Michael Olesen

Luna Mayfly Guide - Step 6

This is how the first segment will look from above.

- Michael Olesen

Luna Mayfly Guide - Step 7

Fold the foam backward, move the tying thread 3 mm towards the hook eye to create a new segment. Fold the foam forward, stretch it slightly, and use the nail of your thumb to compress the foam around the hook shank. Continue until there are, all together, 6 segments on the body, leaving approximately 3 mm of space behind the hook eye. I also apply brown waterproof marker to the 3 rear segments.

- Michael Olesen

Luna Mayfly Guide - Step 8

Here, you can see the nearly invisible joints of the body from the underside.

- Michael Olesen

Luna Mayfly Guide - Step 9

Move the thread forward in front of the foam. Create a hole for the wings in the middle of the foam, at a 45-degree angle, using the dubbing needle.

- Michael Olesen

Luna Mayfly Guide - Step 10

Keep the needle in the foam while preparing the wings.

- Michael Olesen

Luna Mayfly Guide - Step 11

Place 2 selected CDC feathers with the concave sides facing each other, even them up and cut awaywhere the lower part of the feather. I prefer the feathers to be at least 3 cm in length to ensure the finished wings are about 2½ cm long.

- Michael Olesen

Luna Mayfly Guide - Step 12

Remove the dubbing needle and insert the wing feathers into the hole in the foam. Sometimes it works to insert both feathers at once, but often, it’s easiest to do it one feather at a time, depending on the cooperation of the hole in the foam.

- Michael Olesen

Luna Mayfly Guide - Step 13

Tie the wings down on the hook in front of the foam. Begin with a couple of loose turns and then secure the job with some firm wraps.

- Michael Olesen

Luna Mayfly Guide - Step 14

Tie in a Cock de Leon feather, just in front of the foam.

- Michael Olesen

Luna Mayfly Guide - Step 15

Create a small thorax using black CDC dubbing and leave the thread hanging just behind the wing.

- Michael Olesen

Luna Mayfly Guide - Step 16

Wrap the hackle around the foam as a parachute hackle. You can finish with a whip finish under the hackle or around the hook shank as preferred.

- Michael Olesen

Luna Mayfly Guide - Step 17

Here’s a view of the fly from the underside.

- Michael Olesen

Luna Mayfly Guide - Step 18

Pull some of the front hackle fibers to the sides to give the hackle a silhouette similar to spent wings. Stubborn hackle fibers can be removed with scissors, and trim the excess foam as close to the hackle as you dare. In this picture you also have a clear view of the foam crescent from the top, which inspired me to name the fly “Luna Mayfly.”
