No interactions present.
Most noctuids can be done by eye, but there are a few species pairs which are range from difficult to impossible to do by eye - as David says, this (the Uncertain/Rustic species pair) is one of them. For my money they're Uncertain, but I wouldn't like to call them from just a photo, especially one which doesn't show the hindwings
Record your ladybird sightings!
Whereas if I had to guess I'd go for an Uncertain (left) and a Rustic (right).
