About the blog

I have no heavy training... Barely Elementary School. Preferred the wilderness, it became my university, but I got muddy boots and experience instead of School knowledge so my English was therefore quite inadequate. This blog is a project to improve my skills in English language.

We all have our own universe, welcome to visit mine.

Baltic Grayling

Nature ConservationPosted by Uncle Henry Sun, June 19, 2016 20:24:33

From the middle of Sweden and north, you can now see a gray-brown butterfly patrol around the sunlit pine trunks in the mire landscape. It's the Baltic Grayling (Oeneis jutta), a species in the subfamily Satyrinae with a circumboreal distribution. It occurs in bogs and tundra in the north of Europe, the Baltic States, the Urals, Siberia, Northern Kazakhstan, the Russian Far East, Northern Mongolia, Northeastern China, North Korea and North America. (In Canada it occurs from Newfoundland to British Columbia.)

In Sweden, it flies from early June to mid-July every two years, so you could not see it last year and will not be able to see it next. It flies only in even years, so take the opportunity; the next time will be in 2018!

The butterfly often starts at the root and then flits rapidly upwards along the stem, sometimes up into the crown of the smaller pines before popping down to the next pine and continues.

Flights season varies in different places in the world. In Canada, for example, Baltic Grayling flies from late May to mid-June in eastern Ontario, from late June to late July at Churchill, and into August in Newfoundland and Labrador. It is biennial, flying in even years in southwest Manitoba and the west and mainly in odd years from southeastern Manitoba eastward; at Churchill and in the Mer Bleue bog near Ottawa it flies every year.
