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
Larva Larva A larva (plural: "larvae" ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form ("e.g." caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to environments separate from adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water
