What were the Coppers doing?

There were 16 Svensson's Copper Underwings on one parkland Oak trunk at Dingestow Court at 10:30pm last week; checking several other trees revealed just one other single SCU.  There were no obvious sap weeps to attract the moths, so I have no idea what they were doing.  The only unusual thing about the tree was a large nest of the ant Lasius bruneus in a hole on one side, and I wonder whether the ants scurrying up the tree left sweet trails on the bark which the moths were then feeding on.
