The “fly of the month” series for 2026 has included a number Euro nymphs to recognize the competitiveness of fly fishing, For May, the Spanish Bullet is presented.
A Euro nymph is any slim profile nymph fly pattern with a tungsten bead. These fly patterns are designed to sink quickly through the water column so that the angler can establish contact with the stream bottom as quickly as possible using a style of fishing called Euro nymphing, sometimes written as Euro-nymphing and often referred to as contact nymphing.
Euro nymphs come in a wide range of styles and can be grouped into three categories: Perdigons, jig style Euro nymphs, and simply tungsten nymphs. That last category is somewhat deceiving because as a rule, all Euro nymph fly patterns are tied with tungsten beads.
Perdigons - The Perdigon nymph is a style of Euro nymph developed by Spanish competitive fly anglers and popularized by French competitive anglers. These fly patterns are distinct with a slim profile consisting of a hard, body that is somewhat bullet shaped and created by a thin or thick layer of UV resin or epoxy cured over the tying materials. A tail, a body, and a thorax or collar of contrasting color, known as a hot spot. These fly patterns are very simple in appearance and depend on a tungsten to sink very quickly. They are somewhat representative of attractor nymphs which challenge the notion that actual insects must be matched to catch a trout. The strategy behind Perdigons is that getting the fly in front of fish is the most important aspect of nymphing. Perdigons are designed to cut through the water with the least amount of resistance and get to the bottom, stay on the bottom throughout the drift. Perdigons are sometimes tied on jig style hooks and even scud hooks. The overall design of a heavier head and slim body encourages the fly to ride with the point of the hook facing up. Example: Pliva Perdigon
Jig Style Euro Nymphs - Flies tied on jig style hooks are incredibly effective. The heavier tungsten bead and hook design allow the fly to bounce along the stream bottom with the point of the hook facing up compared to traditional hook styles, this resulting in fewer snags. They sink fast and the heavier head causes the hook to bounce along the bottom point up, a key reason why Euro nymphing is so effective. Example: Hare and Copper Euro Nymph Variant
Note: traditional fly patterns have been converted to jig style Euro nymphs, us ing basically the same materials except for using a jig style hook and a tungsten bead in place of a brass bead.
Tungsten Nymphs - Euro nymphs can be tied on any style hook, such as some Czech nymphs are tied on a scud hook. Any pattern can be turned into a Euro nymph simply by using a tungsten bead instead of a brass bead. Generally speaking, all tungsten nymphs are Euro nymphs. What separates these from traditional patterns tied with brass beads is that tungsten nymphs are usually with slimmer profiles. The goal for both is to drop to the bottom and establish contact quickly. Any unnecessary bulk slows down the process and voids any benefits of Euro nymphing. Traditional nymphs such as Hare’s Ear and Pheasant Tail are tied with wrapped lead for weight or with brass, glass, or even plastic beads, all of which are lighter in weight than tungsten. Tungsten has a density of 19.3 grams per cubic centimeter compared to brass which has a density of 8.73 grams per cubic centimeter. If you were to place a 1/8 tungsten bead and a 1/8 brass bead on bare hooks of the same size, the tungsten would drop more than twice as fast. Even using wrapped lead and a brass bead are not enough to match a tungsten bead. Theoretically, tungsten nymphs will get there quicker, which means that your flies are down in the strike zone where the fish are feeding for longer periods of time during each drift, which means you’re covering more water more effectively and with fewer casts.
Euro nymphs helped popularize the idea of the hot spot. Although this is not a new concept, it certainly brought it into the mainstream language of how we talk about fly design today. Many traditional patterns incorporated some sort of trigger point, such as a red tag, red throat, or red belly. Many times it could even be just a sharply contrasting color. Today we often call these color contrasts hot spots, and Euro nymphs have absolutely put more emphasis on their importance in the flies we use to catch trout.
European nymphing techniques are gaining tremendous popularity in the U. S. and around the world. Euro Nymphing is a very effective way to catch a good number of trout and very large trout when the trout are not rising for a dry fly or being too picky for a streamer. Considering trout feed sub surface ninety percent of the time, Euro nymphing gets the fly pattern down deep and in squarely ion front of the trout. Spanish Bullet
Euro nymphing is a very, very effective way to catch fish. Designed by Fulling Mill fly designer Simon Robinson, the SR Spanish Bullet is designed to quickly sink in fast water. The thread body is also coated in UV resin which aids in durability, and the slotted tungsten bead ensures that this fly gets down in a hurry. The olive version of this Spanish Bullet from Fulling Mill is one of the very best Euro Nymphs to run as a dropper. The French Spanish Bullet is a slender, epoxy-covered Euro nymph with a tungsten bead for maximum sink rate and sensitivity. The black body and red butt are complimented with a flashy, pearl wing case and silver tungsten bead. The well-known Spanish Bullet Euro nymph is tied on a super sharp, barbless, 60-degree, typically size 14 jig hook for positive hook sets and does a great job of keeping fish pinned on the hook. The Spanish Bullet Jig is a classic European nymphing pattern upgraded with a jig hook and tungsten bead to get the fly down quicker and keep the hook off the bottom. Tied in size #14 and #16, this fly is a solid producer whether you’re Euro nymphing or dropping it off a larger dry fly. The quill body is also coated in UV resin for durability, and the slotted tungsten bead ensures that this fly gets down quickly. Quickly becoming a “Go To” European style jig nymphs the Spanish Bullet is super effective on very selective trout in broken water. The fly patterns is highly production on seasonal delayed harvest streams and year-round on wild streams, tailwaters and spring creeks tied on hook sizes 12 through 18 with corresponding bead sizes 2.8 mm, 3.8 mm, and 4.6 mm.
