Watch Out For This Hatch Late Summer
20 August 2021 | Sarah
What's happening on rivers?
Given shorter days and cooling weather, water temperatures will be dropping to more comfortable levels that in turn kick start daytime fly hatches once more, chief amongst which will be Large dark olives (LDOs)
. And close on the tail of this common upwinged species will be the much smaller and more delicate looking Pale watery
Where both species occur, they will happily emerge side by side, giving us perhaps some of the best dry fly fishing
in the closing days of the season.
What do you look for?
Most upwings prefer cloud cover for hatching as it makes them harder to detect by various predators, so try to plan your fishing trip to coincide with cloudy, rainy days. Large darks olives are fairly easy to identify as they equate to approx a size 14 hook and as their name suggests they are a dark olive colour.
Pale wateries are much smaller and are typically copied using size 16-18 hooks. Again, as their name implies they are a pale, wishy-washy yellow shade, making them unmistakable
