I think that the point should be made that this normally happens UNDER the
capping; I would have then described them as decomposed rather than melted -
but I guess that it is a matter of semantics. My point was that uncapped,
discoloured larvae - often described as having a 'melted appearance' (and
usually twisted out of position) are normally associated with EFB.

... and would not be seen unless the bees had removed the capping.
