While monitoring Pandemis heparana in an apple orchard in South Tyrol (middle of August), I frequently observed huge moths accumulating within the trap. The trap itself is working with pheromones for Pandemis heparana.

The moth is 4 cm long and at least 1.5 cm in diameter. It is quite solid and has upper wings which are brownish and lower wings which are bright orange with a distinct black part at the end of the wing.

Can you help me to identify this moth?

Edit: The moth was dead when i touched it.

There's a group of moths known as the "Underwing moths" for their brilliant coloured hindwings. I think these are used to startle predators when they get too close. They have the brilliant red/orange with a black border. If you could open the wings fully, it would help with ID significantly.

The genus is Catocala, which translates to "beautiful lowerone"

For some moths of Austria, you can browse images here, which is how I found the genus name.
