PS, Tony,
a pupa of
Drosophila funebris is depicted in Smith's (1989) "An introduction to the immature stages of Britisch flies". In this picture the horns aren't that long.
Another question is what could be the function of such long horns? One would think this enables the pupa to breathe when submerged in water, or rotting fruit maybe?
