During June and July on a nice day, you will probably see a few blue
damsels flying around. The blue flies are the males with the females
a drab olive in colour. When mating, the pair often fly just above
the water surface and the trout will sometimes chase after them,
although with little success. Unfortunately, the general lack of weed
beds in our two lakes means that damsels are quite scarce here but imitations
can be very effective. Damsel flies have a large aquatic
nymph which swims to shore when it is ready to hatch into the
adult fly. It will usually swim just below the surface, looking like a
small fish. It is now when it becomes an easy target for the trout
which can take them enthusiastically with a lot of commotion at the
surface. The nymph can vary in colour from light green to dark
brown, but a mid-olive is probably the most popular colour to try.
When they reach dry land, the nymph will crawl out and after a
short while the adult fly will emerge.
On days when there is not much showing at the surface, the leaded
version is a good ‘search’ fly to have on your leader, let it sink well
down before beginning a steady ‘figure-of-eight’ retrieve. A good
alternative is an olive damsel nymph tied with a gold bead at the
head, this is a great fly whether damsels are hatching or not.
There are quite a few patterns which imitate the blue damsel adult,
it seems little used, but it can be excellent at Hallington. That could
be because the fish have never seen anything like it before, rather
than the fact that it is a good imitation! Its basis is a foam daddy-
long-legs but with blue instead of tan foam.
During the latter half of June and into July, you may come across
fish feeding on pin fry. These will be perch or dace fry which are
only about 15 – 20 mm in length. They are semi-transparent with
prominent eyes, a silver belly and red around the gills. During calm
conditions fry can be seen dimpling the surface in large shoals and
the trout will not be far away. Try a Sinfoil’s Fry, Peter Ross,
Butcher or a Silver Invicta, all of which look like small fish. A small
floating fry using deer hair or white foam fry are also worth a cast.
Most flies mentioned in previous months will continue to work,
especially those to imitate midge pupae which are now larger and in
a wider variety of colours.
From the end of May for a couple of months there will be some
Mayfly hatching at the surface. These large upwing flies are easily
imitated but I have generally found that the trout seem to be quite
scared of such a large floating fly. The fish will often ignore them or
just splash at them. Having said that I have spoken to other
members at Hallington and some have had good fishing with dry
mayflies. It is still worth trying a floating imitation if you see fish
taking them but a nymph imitation such as Walker’s Mayfly Nymph
will probably produce more hook-ups.
