The surface feeder
200 million years of training has made the salmon one of the most successful predators in the northern hemisphere...As soon as insects start flying the salmon parr has attention pointed up-wards..
The river surface is a superior hunting ground to the salmon parr and a highly hazardous area to the water insect seeking to leave the river, or that land insect struggling not to drown in it. The Atlantic salmon is a animal that throughout its youth has a very high level of surface feeding - and attention is pointed upwards as soon as temperatures rise and insects starts moving. Caddis, stone flies, mayflies and a whole line of terrestrials are on the menu. Any mark that these insects might make landing or leaving from the surface is easily detected by the salmon parr that often will have to take a hasty decision if it is to seize its quarry. It is this particular ability to detect and capture things in the surface that makes the dry fly so effective for adult salmon.
Do salmon feed in fresh water?
Even though It is generally known that adult salmon will leave behind its greedy way of life and go into a state of anorexia when entering freshwater - It is a myth that the salmon wont eat while staying in fresh water - The angler fishing with the worm will also tell you otherwise as the salmon now and then will swallow worm and hook. New science shows examples of eating behaviour among up-to 40 % of the adult salmon in the region of Northern Norway. In some rivers salmon diet would include both land and water insects.

With lots of insects on the water salmon may part-take in the feast along side with its cousin the trout - and rise to the stream of hatching insects as frequent as Mr. Trout. Such rare occasions could call upon a fly that would match the hatch so to speak - But on a regular basis it is rarely necessary to match the hatch and salmon will respond well to flies that look like big caricatures rather than imitations of the insect that it is meant to portrait. The main characteristic that we want to feature in our flies is the element of entrapment - We actually want to construct a fly that will rest in the surface film with little to show under water. We have found that a light and high floating fly will out-fish the fly that is sitting low in the surface. It is in fact as if the magic or rather: deception is lost when the ability to stay high-and-dry is gone. Buy flies
A big forest ant Formicidae family Still with its wings intact. This fellow measures more than 1,3 cm. During summer months swarms of these resilient insects will leave their ant-hill´s to find new territory. Thousands of them will end up in the river system - where parr, trout and adult salmon will find them. Yet another little bug worthwhile having represented in the fly box.
A dead adult caddis from the limnephilidae family - this specimens measures more than two cm. (excluding the long antennas) and is a sought after meal by any carnivore. These remarkable
insects can be seen by the riverbank in the thousands during summer months. Members of the caddis family is also some of the earliest and last flying insects to be found at the river bank. Behaviour and activity of this large group of critters is a centrepiece in the world of dry fly tactics and anglers shouldn't be without imitations of it.
More than just a accidental snack...This grills had devoured on a whole rang of insects - water and land. Note also the little pice of worm -probably bait from a angler downstream. Water 12 degrees Celsius 53,6 degrees Fahrenheit
A all important terrestrial in Northern Scandinavia is the moth of the Geometridae family. A large group of insects that now and then comes in contact with the water and salmon. Little parr will follow these insects closely when they flutter across the river - And if given the chance they will grab it jumping clear out of the water. Personally i believe that it is the plentifulness of these insects that makes the Bomber pattern particularly good in some river systems.
