I’m actually a Floridian and I am currently in the Bernese Alps of Switzerland. I came across an interesting beetle and I’ve been trying to identify it. Although trained in biology, my interests are plants and fungi, so beetles are a bit of an unknown to me. I am hoping someone can help me with this beetle which was feeding and mating on Petasites albus, White Butterbur. It appears to be Chrisolina corulans, but it was not on mint and I saw no mint in the area. I did find one reference online to this beetle photographed on a composite daisy like plant, also in Switzerland. Does anyone have any comments? Thank you.
