Among lepidopterans, some of the sperm transferred is apryene or anucleate, and these are also suggested to be used for female nourishment (Boggs 1995).

In a series of investigations, Bill and his students and colleagues showed that marginal bands occur widely in the circulating cells of invertebrates from several phyla, in dogfish and amphibians, but also in very young, developing marsupials and in camelids (the requisite exception), which have anucleate, but elliptical erythrocytes.
