DOI: 10.1002/jmor.21143
Abstract: Little morphological information is available about subretinal pigment shields in insect compound eyes, especially ultrastructural information. The latter is however needed in order to detect possible smallest projections that emanate from pigment‐granule‐bearing cells and pass… read more here.
