“It is definitely not good," she tells BBC News NI."In three weeks in July and August, there are so many days that there is nothing to report.”

Butterflies aren't the only insects which are absent.“We see the same in the numbers of moths," Ms Muller explains."We monitor some species that are very numerous that you would expect to see 30 or 40 in one night in your moth trap, you are only seeing two or three.

“That tells you something, that some of the common species are not doing well.”Rosie Irwin of Butterfly Conservation says habitat loss, pesticide use and climate change are all impacting the population numbers.

This year’s fall in numbers has been exacerbated by the wet spring and late arrival of summer temperatures.

Butterflies also need some warm and dry conditions to be able to fly around and mate.All of these issues have been discussed for years, but they have suddenly attained a new sense of urgency with Trump's apparent bid for control of Greenland.

But regardless of who sits in the White House, the question is whether Greenlanders would see any benefit in raising cooperation levels with the United States - and if so, to what extent?"Greenland's national project is all about spreading out the island's dependence in order to have as many ties as possible with the outside world," says Ulrik Pram Gad, a senior researcher at the Danish Institute for International Studies and an expert on the Arctic region.

It is in this context that some Greenlanders are warming to the model of a "free association" with either Denmark or the United States – replicating a similar loose arrangement between the United States and certain islands in the Pacific."The problem is that Greenland feels swallowed up by Denmark," says Mr Pram Gad. "It aims to feel less constrained and less dependent on just one country. Free association is not so much about 'association' and more about 'free'. It's about having one's own sovereignty."
