Why are we mapping geometrids?
During the last few decades moth outbreaks in the birch forest has occurred further north and further inland than previously. We think it is caused by a milder climate. It is therefore important to acquire updated information about the distribution of the moth species that cause outbreaks. The least known of the outbreaking moth species in the birch forest is the scarce umber moth (Agriopis aurantiaria). We know it has spread northwards as far as Troms. But exactly how far north and east is it present? Can it be found in inner parts of Troms? In Finnmark? In northernmost Sweden and Finland? We hope the app “Målerjakt” (Moth hunt”) and the efforts of many volunteer moth hunters will help answer these questions. We need your assistance!
How can you contribute?
Download the app Målerjakt and let the hunt begin! Search near garden lights on your house, your cabin, on your way to school, or anywhere you go. When you find a moth you believe to be the scarce umber moth, take a picture with the app and send it. If you are unsure whether it is the right species, send it anyway. All pictures will be checked by an expert, and only those that are certain to be scarce umber moth are added as new records. Visit the map in Målerjakt to see how your observations help us a better picture of the distribution of scarce umber moth in the northern birch forests. If you give your name and email when you submit pictures, you will receive our news letter with updates on the progress of the hunt.
