Video: Father and son set off on a Strangford Lough island-hopping butterfly hunt

A nature-loving father and son will be hunting for butterflies on the islands off Strangford Lough as they take part in one of the largest ever citizens' conservation projects in the world.

Cadogan Enright and nine-year-old Cad Og start on their ecological adventure today and will spend the next seven days canoeing between 68 islands on the lough in search of butterflies.

They aim to count as many butterflies on each island as they can over a 15-minute period.

Their trip is part of the Big Butterfly Count - the world's largest butterfly survey which encourages people to spot and record common butterflies during three weeks of high summer.
