About Alexandra
An old exciting pattern with an interesting history. The Alexander was first called ‘The lady of the lake’ then renamed after Queen Alexander. It is still best fished in lakes for Trout as a fry imitator, retrieve in a series of sharp irregular jerks, although it fishes well in rivers but mainly for Sea Trout

Alexandra was reputed to be such a killer in the mid 1800’s that it was banned on some waters.
