Aeshna subarctica – Suoukonkorento – noordse glazenmaker

Figure 1. Distribution map exuviae A. subarctica.

In 2016, I found larval exuviae in one lake, mustalampi (4 females, 22-07-2016), and in one pond near wilderness hut Eskola (3 males, 13-07-2016). In 2017, the focus was in particular on sites with well developed peat bog vegetation. This resulted in 5 new locations with exuviae of A. subarctica. I also observed one adult. So far, the species was recorded form 8 locations, all of which have serious surfaces covered with peat bog vegetation.

The species overwinters 3 times (2-4 times). The larval excuvia have a beautiful green shine.
