Aecidium mori was to "Peridiopsora mori" (Barclay) K.V. Prasad et al. 1993, a combination of all three names, but it has not been adopted at all in taxonomy. 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 post-larva is characterised by the use of abdominal appendages (pleopods) for propulsion. The post-larva is usually similar to the adult form, and so many names have been erected for the stage in different groups. William Elford Leach erected the genus "Megalopa" in 1813 for a post-larval crab; a shrimp post-larva is called a "parva"; hermit crab post-larva are called "glaucothoe". In the Branchiopoda, the most basal group of crustaceans, there is no metamorphosis; instead, the animal grows through a series of moults, with each moult adding various numbers of segments to the body, but without any dramatic changes in form.
