Product Description

Mayflies are found around the world, from Kamchatka in the east, to Montana in the west, New Zealand in the south and Sweden in the north. The hatches are often rich and short. Most species hatch during early summer and it can result in a feeding freenzy with fish species like browntrout, turning on there selective mood. J:son Match’n’Catch makes it easier to select the right fly and fit it to what ever mayfly the fish is feeding on, no matter what stage of the life cycle. 

J:son Mayfly Dun 1- Green Drake

The largest J:son imitations of mayflies are tied to perfection. Mayfly Dun Size 1 imitates mayflies such as the Green Drake and similar large sized mayflies. We recommend that you use a J:son Swivel for all your fly fishing, no matter what type of fly you are using. However, it is necessary to use a J:son Swivel whenever you fish a size 1 or 2 J:son fly.

Size: 28 mm / approx 1 1/8 in. Hook: J:son SS.DF #10; Olive/Grey.

Latin: Ephemeroptera

All mayflies have a life cycle that goes from egg to nymph to adult, fluttering about. This type of life cycle is called Hemimetabol transformation. As a fly fisherman we are interested in various stages of this transformation – the nymph, the hatching insect, the adult (called a dun) and spinner – the last stage of an mayflies life where it dies on the water with it’s wings spread out from each side of the body.

Many of the mayfly species are similar in size, shape and color. Due to this, we as anglers do not need to carry around several hundred imitations in our fly box. Most mayflies hatch during day time, but they lay their eggs during evening and night fall.

A newely hatched mayfly is called a dun. They are usually brighter in their colors than the adult egg laying female which is called a spinner.

There are many flies that are supposed to imitate mayflies, but few are actually tied with the real insects in mind. A good imitation that will handle even the most picky trout, has to have the right proportions, silhouette, looks, colors, shape and give the right marks on the surface – J:son’s flies do all of this.

It is good to keep in mind that the same family or species of mayfly might have several names depending on country and even districts within the same country.

J:son Match’n Catch - Mayflies

As a flyfisherman you need to know that a hatch always starts at the bottom. A skilled angler will not only carry imitations of duns in his or her box, but all the stages of the life cycle will have it’s copy in the fly box.

The hatch usually starts with the nymphs moving around on the bottom before swimming to the surface or crawling up on a plant or stone to hatch so you will need to follow these natural steps. Begin the day by fishing the nymph near the bottom and as the morning ensues, start to fish your imitations further up, towards the surface. When you see that the fish feeding near or on the surface, switch to an imitation of a hatching mayfly. Keep on moving in that diretion as the feeding changes. Move on to duns as soon as the fish starts to feed on these instead, and then end the evening by fishing spinners when you see them floating on the surface.

And do remember, match your fly, it’s color and size, with the looks of the hatching mayfly.
