April
The newspapers report that the air temperature in the last ten months has always been significantly above the expected. Vegetation is at least 1 month ahead. After exceptionally warm April days of up to 28° C, there are repeated drops in temperature, then it suddenly returns to 0°C at night. The butterfly season starts slowly: After several observations of Aglais urticae, Gonepteryx rhamni, Anthocharis cardamines and the first Lycaenidae are flying. As soon as the sun shines, there is a strikingly large variety of wild bees and hoverflies. Spiders and beetles are also easy to spot. Many thanks to all of you who can help with IDs!
