It was decided later in 1993 that "Aecidium mori" was a different, distinct species, and this taxonomic assignment was kept. All of these differ from the species of "A. mori". Mulberry rust is a disease caused by "Aecidium mori", which only occurs on the "Morus" plant, the familiar "mulberry". "Morus" is grown for the breeding of "Bombyx mori" (silkworms) as part of the silk industry. The leaves of the "Morus" plant are the only
Crustacean larva Crustacean larva Crustaceans may pass through a number of larval and immature stages between hatching from their eggs and reaching their adult form. Each of the stages is separated by a moult, in which the hard exoskeleton is shed to allow the animal to grow. The larvae of crustaceans often bear little resemblance to the adult, and there are still cases where it is not known what larvae will grow into what adults. This is especially true of crustaceans which live as benthic adults (on the sea bed), more so than where the larvae are planktonic and therefore more easily
