We have transformed Drosophila with Hermes elements tagged with EGFP
and EYFP (yellow) driven by the Actin 5C promoter.  While it can be
tricky distinguishing faint EGFP fluorescence from background fluorescence
in the abdomen of adults (from the yeast in the food), larvae and pupae
are bright and easy.  EYFP can be distinguished from EGFP.
  We have not generated minimal promoter driven constructs, but that
should be fairly easy.  Transformation with Hermes goes much better than
P (I've gotten as high as 100% efficiency), but Hermes does interact
with hobo.  I'll present this in March in Pittsburgh, but I'll be happy
to share data if it'll help you - send me a personal email.
