Yellow-green flies???

I'm relatively new to drosophila, and have been doing RNAi for a gene 
of unknown function using a UAS-inverted repeat construct.

I see late eclosure, but possibly more interesting is a pale 
yellow-green colour in newly eclosed males. It is particularly 
noticeable on the ventral side of the  abdomen, but is no longer 
noticeable after about 12 hours. It is more yellow in colour than the 
jade-green stuff that newly eclosed flies secrete.
This colour occurs only in males and in none of the control flies, 
male or female.

Before I go overboard trying to identify what this yellow-green stuff 
is: has anyone seen anything like this before???  Being new to flies, 
I don't want to be chasing a red-herring...


PS please cc me if you reply to this.
