A father and son team are about to embark on a week-long canoe trip around Strangford Lough in support of the Big Butterfly Count.
Downpatrick independent councillor Cadogan Enright and son Cad Og, eight, will visit up to 50 of the lough’s many islands.
Last year more than 46,000 people took part in the UK-wide initiative, counting 800,000 butterflies and day-flying moths in their gardens and local countryside.
Cllr Enright, 50, is due to set off on Friday.
He said: “We are aiming to visit about six islands per day, camping on a different island each night.
“Strangford Lough is one of the most important wildlife sites in Ireland and its islands are a fantastic place to look for butterflies.”
The count runs until August 10, with everyone invited to jot down which butterflies they see during a sunny 15-minute period and send their sightings to www.bigbutterflycount.org
