A fly that seems to have a smiley face on its wings ! It flew onto the window of a boat on the Norfolk Broads. ID wanted if possible please.
No interactions present.
yes sorry about the detail - it was on the inside of the window so its body is mainly in silhouette against the brighter outside light. Thanks for the Yellow dung fly suggestion - I'll see if they have the wing patterns.
