I posted a short video on a pet silkworm spinning a cocoon and got 25 Million hits but under the comment section i found out that there is a lot to know about silkworm's life! So here is a little documentary on silkworm which you can easily fins in your garden and even can raise as a pet , I bet all questions answered in this video. • Chapters • 0:00 Introduction • This is the story of a silkworm ! • 0:05 Silkworm laying eggs • 0:32 Total Life cycle of a silkworm Timelapse • 1:02 Silkworm egg hatching requirments • 1:24 How to store silkworm eggs • 1:47 Larva Stage and food • 2:14 When does Larva start to cocoon and how can we know • 2:30 What does silkworm do right before spinning a cocoon • 2:50 How does a silkworm start to spin the cocoon • 3:14 Life of silkworm in the cocoon • 4:08 Silkworm's birth out of the cocoon • 4:45 How to distinguish between male and female silkworm moths • 4:56 How Silkworms mate each other • 5:10 How and when silkworms naturally die • 5:18 How silk is produced • • • Silkworms will experience 12 hours of sunlight, and 12 hours of darkness per day, • a temperature of 23-28 degrees celsius, as well as humidity levels of 85-90%. • Under these conditions, your eggs should hatch in a period of 7-10 days. • However, • it is very hard to achieve these conditions without an incubator, and it is common practice to just make do with the weather in the area in which you live. • In Most parts of the warmer world. • a Silkworm will naturally hatch in late July to early August – depending on the weather where you live – • It is recommended that you store all of your eggs in a a cold space (a fridge is ideal) because if there are fluctuations in the weather, your eggs may hatch earlier than expected. • When placed in a cold area, you can control when your eggs hatch, therefore ensuring they will always have a food source. • If your eggs have been placed in the fridge, they will begin developing and hatch after 10-25 days, • After 20-33 days of constantly munching away at Mulberry leaves or chow, • your Silkworm will feel the urge to cocoon. • When you are feeding the silkworm at home make sure you give them fresh supply of leaves everyday • You also make sure that you clean up their wastes and excretes . • Normally tiny black spots are their poop. • • Larva that are ready to cocoon will be noticeable to the human eye, • as they will appear translucent and yellowish in colour. • Just before it begins cocooning, the Silkworm will excrete a runny fluid in order to clean out its system and prepare it for the last stage of its life-cycle. • That is also the stage where the Larva would change its skin four times. As Its gaining its size the outer skin is taken off . • This process may take upto 24 hours for each skin change. • But the last time is the longest and takes 48 hours. • • It will then ooze a tiny drop of Silk for anchoring, before going on to draw one long, continuous filament of Silk by swinging its head to-and-fro. • This process can take up to 48 hours for the Silkworm to fully complete, and the result will be a perfectly ovate cocoon, with one continuous strand of silk up to 1 kilometre long! • Inside the cocoon, the Silkworm will moult for the last time, as it approaches the last stage of its life-cycle to become a moth. • Sometimes Silkworms do funny things, and this is evident when a Silkworm decides to spin a cocoon with a friend! • When this happens, the cocoon will be noticeably larger, • however, if the two are members of the opposite sex, sometimes the cocoon does not hatch – and you will open it to find two dead Silk-Moths and a bunch of eggs inside • • Silkworm spends most of his life time in the cocoon ! • It is not taking rest in the cocoon at all. • Its contantly turning into a beautiful moth by changing its color on frequent basis. • By the end of this phase the moth has a thick skin inside the cocoon and protiens of the body are totally edible and in many parts of China they are eaten after boiling. • After 10-14 days of developing into a moth in its cocoon, the Silk-Moth will appear from the cocoon and will excrete a brownish fluid upon emergence • – don’t worry, • this is completely normal, and is a sign the the Silk Moth is cleaning out its system. • Silk-Moths cannot fly, as a result of thousands of years of domestication, however male Silk-Moths may leave their container/shoebox as they search for a female mate. Some males may be able to almost fly if you drop the from a small height, however it is uncontrolled, and they will hit the ground after a few moments. • It is quite easy to separate the male and female Silk-Moths, with the females having larger abdomens and males possessing smaller abdomens. Males also tend to be more active, as they are constantly searching for a mate. The moth lives a very brief life of 5-10 days, with males generally living longer than Females. • #silkworm • #cocoon • #caterpillar • #amazingviralvideo • #documentary
