The blue-winged damselfly is associated with particularly high water quality, as it is mainly found in clean waters. In the region around Paderborn, the blue-winged damselfly can be spotted with a bit of luck in the Krollbach stream in the Senne. Recently, the butterfly-like insect with the blue-green body colour can also be found as a mural at the Talle. In her work at the substation, artist Elisa Wolke focussed on the theme of water. The compound H20 is of particular relevance to the human organism, as the body consists of around 60% water. The molecules in our body are responsible for vital detoxification, metabolism and temperature regulation. After just 24 hours without water, the first signs of dehydration become apparent, which the artist also quickly realised at almost 30 degrees in August. Elisa Wolke's work in Paderborn didn't just make her sweat due to the high temperatures. ‘I had far fewer cans in dark blue available than initially planned. So I had to change my concept a little. But in the end, I like it much better this way.’ At the centre of her wall painting is the motif of the dragonfly and the depiction of a water landscape. The trained designer loves variety in her art. ‘After a rather colourful and friendly work, I now feel like designing something darker again. I like the contrast.’ She was a little surprised when 30 employees from the company suddenly stood behind her to take a tour of the plant. Otherwise, the substation on the Talle is a rather bleak and deserted place. Elisa was only visited by the numerous biting flies and grasshoppers. From now on, however, the excursion is worthwhile. After all, the new mural is on the way to the Senne, where you can observe the damselfly in the wild.
