The Greenland High Arctic is a bare sparse place.

Rather than tall trees, it has tundra, ground-hugging vegetation, and rugged Lord of the

ring style vistas.

Well, I don't know, it's not exactly New Zealand but kind of similar landscape.

Miko Tuyujanin is an ecologist at Helsinki University in Finland.

The winter season is like six seven months so everything

basically happens during the short summer season including the white yellow

bloom of Mountain Avens a hardy Arctic shrub.

Even though it's small, it could be like over 100 years old.

It's pretty good at surviving harsh conditions.

Teushenin and his colleagues set out to census which of the many local insects visit mountain havens by summer and help with the pollination.

So they planted 2,100 sticky flower lookalalikes, has traps, and identified stuck visitors by their DNA.

Two-thirds of all local insect species visited, but it was one particular fly, a relative of the

humble house fly that showed up most often in those

spots where the tundra shrubs had successfully set seed, meaning more flies appeared to be a

good thing for the Avons.

The study appears in the proceedings of the Royal Society B.

Here's the bad news.

A 2013 study found that the Arctic flowering season is shortening.

The numbers of fly pollinators is down as is the
