Blog, news and reviews from Snowdonia Fly Fishing Guides
The last few years there was a profusion of dragon flies in and around my pond, but this summer not so many. There were plenty of nymphs and empty shucks in the pond so why no adults?
Then one afternoon I saw a sparrow successfully plucking a beautiful, iridescent blue, broad-bodied chaser from the air, a feat of considerable acrobatics that provided a significant feast for one of the bird's young brood. So the mystery was solved.
Having finished breeding the sparrow colony has dispersed, giving the late hatching invertebrates a chance. Yesterday I watched as a common hawker emerged from her nymphal case (shuck) to dry herself before flight. I wish her well in finding a mate to complete the cycle of life.
Bugs are the pulse of this planet, without them we would all perish very quickly, they are cleaners, pollinators and a food source for other creatures.
As I've mentioned previously insects are under great threat and we should make greater efforts to protect them. On land it's evident that they are not as prolific as they once were, but underwater they are out of sight and largely out of mind. Our aquatic invertebrates are being decimated by pollution from agriculture, industry and sewage treatment plants with a chemical cocktail that not only kills them and their eggs but also destroys the habitat they depend upon.
This cute little critter is a heptageniidae (or flat bodied stone clinger) that will mature in to a beautiful up-winged fly (mayfly). It spends most of its life clinging to the underneath of a stone in the river and cannot survive if there is too much silt or algae on the gravels that form the riverbed. They were once common on a part of the river I often fish but over the last 5 or 6 years they have become much more scarce. At the same time a dairy farm expanded its operation and is spreading large amounts of slurry onto the fields bounding the river. The nutrients and chemicals from the slurry finds it's way into the water and creates algae on the once clean gravels and fine suspended sediments that drift in the river, all of which is detrimental to aquatic life.
This little bug was carefully returned to it's watery home and I hope it gets the chance to mature, breed and sustain the fragile population that's trying desperately to survive in a man-made hostile environment.
Just look at that face, cute or what? Bugs really are endearing little critters and this stonefly nymph proves the point.
Of great concern is that aquatic invertebrate numbers are collapsing at an alarming rate,
Riverfly insects have declined 59% since 1970, indicating poor water quality & an unstable food chain.** This is a growing problem not just in Britain but throughout Europe, Germany has recorded a decline of 75% in 27 years.
Not so long ago scraping squished bug gloop of the car windscreen was an essential task after a long drive, alas those days are gone. And this is worrying, not just because bugs are cute, but they are an essential part of the food chain for fish, birds and mammals.

Now I freely admit that Euro/Czech/French (call it what you will) nymphing isn't my favourite way to catch grayling, but it can be effective.
Personally I like to cast a fly line when I'm fishing and get as much pleasure casting as I do catching fish, and tossing a team of nymphs just doesn't do it for me, I find nymphing boring (there I said it)!
But it is a very useful tool to have in your angling armoury and when the fish are in deep fast water it's a technique I employ to great effect.
