Orthetrum cancellatrum
Black-tailed Skimmer/ Stor Blåpil
Vest Stadil Fjord,West Jutland
Black-tailed
skimmer is common in North Africa and the most of Europe. In Norway it
is considered extinct. In Denmark it is known from all districts.
Since Denmark is on the northern border of its area of distribution it
is possible that the Danish occurence of black-tailed skimmer might be
influenced by climatic changes.
The male has a blue
abdomen with a black tip and transparent wings and the female has a
yellowish brown body with black zigzag marks along the abdomen and the
transparent wings. It is an active skimmer that patrols its territory
aggressively frequently resting on patches of bare ground or stones
although it will occassionally rest up in vegetation. It favours open
areas of still water that has a hard not muddy substrate.
How to help dragonflies and skimmers:
Leave
patches of bare ground around the edges of larger water bodies and
leave cut grass and other vegetation to dry out in ‘habitat piles’.
These pale areas will attract basking dragonflies. Skimmers hunt from
low perches, so placing a few sticks or twigs close to the water’s edge
will also encourage them.
