Pronunciation: [ˈe͡ɪlanθəs sˈɪlkwɜːm] (IPA) 
The correct spelling of the species commonly known as the ailanthus silkworm is "Samia cynthia ricini". The first part of the name refers to the genus of the moth, Samia, while the second part, cynthia, is the species name. The final part, ricini, refers to the moth's preferred food source, the castor oil plant. The pronunciation is /ˈseɪmiə ˈsɪnθiə ˈrɪsɪni/, with stress on the second syllable of each word.
The term "ailanthus silkworm" refers to a particular species of silkworm scientifically known as Samia cynthia ricini. It is a moth species belonging to the family Saturniidae and is commonly found in regions of Asia, such as China, Japan, and Korea.
Ailanthus silkworms have a distinctive life cycle, beginning as eggs laid by female moths on the leaves of the ailanthus tree, which is their primary food source. After an incubation period of about two weeks, the eggs hatch into larvae or caterpillars. The caterpillars are characterized by their vibrant green color, with numerous tubercles and spines along their bodies for defense against predators.
As the caterpillars grow, they molt several times, shedding their skin to accommodate their increasing size. After reaching maturity, the caterpillars spin a cocoon made of silk threads, attached to the branches or trunk of the ailanthus tree. The cocoon undergoes a metamorphosis phase, and within a few weeks, a fully developed moth emerges.
Ailanthus silkworms are valuable for their silk production, similar to mulberry silkworms. However, the silk they produce is coarser, tougher, and less lustrous, making it more suitable for durable applications such as home furnishings and industrial materials. The extraction of the silk involves unraveling the cocoon and reeling the silk thread from it.
Apart from their economic significance, ailanthus silkworms also play a role in ecological balance. The caterpillars help in controlling the ailanthus tree population by feeding on its leaves, which are not favored by many other herbivores. Therefore, ailanthus silkworms contribute
The etymology of the term "ailanthus silkworm" can be broken down as follows:

2. Silkworm: The word "silkworm" refers to the larval stage of the silk moth (Bombyx mori), which is responsible for producing silk. The term "silkworm" is a compound of two English words: "silk" and "worm".
