Found in South Cumbria, 18/10/2022. Update; 24/10/2022. Thanks to Eric I am now satisfied this is neither of the above, but in fact a (female) Pollenia rudis. ( Unless anyone can convince me otherwise ? ). Duncan Cooke attached the following image: [290.27Kb] Edited by Duncan Cooke on 24-10-2022 00:28 [img][/img]

To be more sure we need a dorsal view. (Olga Sivell: Blow flies, 2021) Greetings, Eric Kloeckner
