Day Fourteen

Today, I sold three batches of fifteen silkworms.

Persistence is paying off.

I have been listing them on a community facebook page so I have sold four batches through this listing.

Because the weather has remained cool (it's 13.6 oC outside tonight) the silkworms do become less active.  I have switched the heating on so they will be alright.

The two plastic shopping bags full of mulberry leaves that Mr Honey Pie picked and which I posted about yesterday are almost gone.

My Dear Daughter took some for her silkworms while mine have continued on their feeding frenzy despite the cooler weather.

DD has commented on how Grand Daughter is showing responsibility by for her pets by feeding the silkworms herself.  She is only four years old.

By being responsible for her fifteen pets, she can demonstrate that she might actually be ready to have her own larger furry pet...like a cat or a dog.

By the way, the silkworm larvae are no longer furry.

Their skin is smooth now and are a much lighter colour.

Some of the larvae are moulting again.  Second or third moult?  I'm not sure,  but probably third.

The fourth moult is the final one and after the fourth moult, the silkworm, once mature, begins to spin a cocoon using a silk filament.

The silk filament is actually the silkworm's saliva.

The next stage, that is when the cocoon is formed, is called the pupa stage.

Day Seven

The eldest of the silkworms are now seven days old.

By now some of these older brothers and sisters will have become too big for their skins; literally.

To cope with this situation the little critters moult, that is, they leave their old skin behind.

The time between each moult is called an instar.

Some of the silkworms have moulted twice since hatching last Thursday.

You can see some old skins above, they look like shrivelled up silkworms.

The first time you see this you might think that the silkworms are dead and take you by surprise, which is what happened to me.

Then I remembered that they shed their skins, just like a snake.

Silkworms moult four times, there are five instars during this stage.

The first stage is the wait for the eggs to hatch (incubation).  The egg stage is called Ova.

The second stage is the silkworm stage and is called Larva.

During the Larva stage, the silkworms eat and eat and eat.

Silkworms eat mulberry leaves so if you want to keep silkworms as a pet, then you need a mulberry tree.

The second thing you will need is a tank or box with good airflow to keep them in.

The third thing you will need is some time each day to feed them and to clean up their house.
