Unidentified Moth - Copper Underwing?

Unidentified Moth - Copper Underwing?

Observation - Unidentified Moth - Copper Underwing? - UK and Ireland. Description: Interesting, this, because there were four of these moths together in a hide; the surrounding habitat was marsh and shrubs, including willow. They were quite active (it was a warm day). Perhaps an inch long. Best guess, a Copper Underwing.
