Which species of Parageron is it? incisus, gratus, auratus?
It was resting on a semi-open flowerhead of Calendula arvensis in a cloudy-slightly rainy day in open terrain over dry grypsy soil next to a village. Photographed at El Burgo de Ebro (Zaragoza, NE Spain) on 23th March 2025. 183 meters over sea.
Size was relatively big, I can't say exactly but it would be almost as bulky as a small housefly.
