Hi Julian,

this is what you want:

  \startsectionblockenvironment[bodypart]
    \setupbackgrounds
      [rightpage]
      [background=butterfly]
  \stopsectionblockenvironment

The last line adds backgrounds to every page. And without doublesided,
there are not right and left pages.

And you don’t need the \define and \setlayer after \startchapter.

A complete sample would read:

  \setuppagenumbering[alternative=doublesided]
  \definelayer[butterfly][state=repeat]
  \setlayer[butterfly]
    [hoffset=.99\textwidth, voffset=1cm]
    {butterfly}
  \startsectionblockenvironment[bodypart]
    \setupbackgrounds
      [rightpage]
      [background=butterfly]
  \stopsectionblockenvironment

  \def\rubbish%
    {\dorecurse{2}
      {\chapter{Chapter}
        \dorecurse{25}{\input knuth}}}
  \starttext
  \startfrontmatter
  \rubbish
  \stopfrontmatter
  \startbodymatter
  \rubbish
  \stopbodymatter
  \startappendices
  \rubbish
  \stopappendices
  \startbackmatter
  \rubbish
  \stopbackmatter
  \stoptext

I hope it helps,

Pablo
