Very similar to A. nemoralis. Please read ID notes.
No interactions present.
The 2nd antenna segment in A. nemoralis conforms with the other segments colour, in being all black too. On the page for A. confusus on British Bugs it depicts it with the basal ⅔ of the same segment as orange. As to it being a relevant factor in splitting A. confusus from A. nemoralis, is a question to which I have no answer.
