Blog, news and reviews from Snowdonia Fly Fishing Guides
This time last year we were in the middle of a heat wave with temperatures over 15 degrees Celsius warmer than today. Whilst we've not had much rain the last few weeks and the rivers has been at summer lows, storms over the weekend lifted them significantly.. They are still high but just fishable and with plenty of fresh water and food the fish have become decidedly lively.
The images below are of a male and female large Stonefly (Plecoptera microcephala). They are very easy to tell apart as the male has tiny wings, so small he is incapable of flight, where as the female has much longer wings and has to go in search of a mate. The nymphal stage is shown in a previous post.
I bought size 18 jig hooks as I wanted to tie some small bead headed patterns. Well that didn't work out as planned!
How difficult could it be to have uniform hook sizing? For the life of me I don't know why manufacturers make it so difficult. There is no convention other the smaller the number the bigger the hook but even that is only true until size 1 after which the rules change and a 1/0 is smaller than a 2/0 which is smaller than a 3/0 etc.
To make matters worse different brands have different sizes for the same hook number. So a size 14 or 16 from company X will be different to company Y. Some manufacturers don't even seem to have a sizing convention for their own hooks. the picture below shows hooks of the same brand but different models. Confused? You're not alone.
The BL154 size 14 is clearly bigger than the size 16, that's good, but the size 18's with a different code are bigger than the size 16, that's bonkers!
When will hook suppliers come up with a sensible sizing formula for all hooks? Answer, probably never.
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.
