comparing semaphoronts

[Barry M. OConnor]

I'm looking for studies where authors have compared cladograms generated
from characters derived from different life stages of the same organisms,
the semaphoronts of Hennig.  I'm aware of Brooks' work with the cercariae &
adults of trematodes, but am looking for similar explicit comparisons
dealing with holometabolous insects, crustacea, or other groups where
discrete "metamorphosis" is part of the life history.
        Thanks for the help.
