Eggs :

ideally eggs should be placed in a small clear box with a tight fitting lid. Keep between 21c & 28c. out of any direct heat source & no direct sunshire. place a small damp piece of tissue in with the eggs to help maintain humidity. Hatching will take place in 7 to 14 days.

 

Larvae :

The larvae may not all hatch on the same day. As they do hatch remove them to a separate container with fresh foliage. Their native food plant is Ricinus communis, Caster Oil. Fortunately they readily accept garden hedge privet as an alternative & they will also eat Portuguese laurel, both of which are evergreen.

Your larvae have 5 stages of growing. Each stage is known as an instar. In between these growing stages they moult their skins, at moult they will stop eating.

Give them fresh food every day & clean out the rearing container.

The first 2 instars your larvae will be green at 3rd onwards they turn white.

Once the larvae are at the 3rd instar transfer them onto cut food in water.

Your fully grown larvae will be huge & eat large amounts of foliage. Make sure you have access to enough foliage to rear them.

Once fully grown they will prepare to spin a cocoon. Firstly they will empty their cut, messy but essential. Now they will wander to look for somewhere to spin, make sure they are contained. They will normally spin within the foliage or the corner of a cage.

Cocoon :

Once the cocoons are spun leave them for 7 days. You can either leave them where they are or gather them up & hang up for hatching. Your moths will hatch 4 to 6 weeks later, depending on temperature.

Moths :

Once the moths hatch place them in a cage. A simple cardboard box with netting pegged to the front is sufficient. They do not feed & will mate the first night. Mating will last for several nights before the female lays here eggs.

 

Try to maintain a temperature between 21c & 28c throughout rearing. The warmer they are kept the faster they will grow.

 

Make sure you keep them clean & with fresh food. If you have any questions please don't hesitate to contact me using the contact info on this web site.

 

This species of silk moth is one of the easiest species to rear & is ideal for beginners & children. It is continously brooded & can be reared all year round.
