Artificial Mulberry Diet powder for 20 Silkworms
Availability: NOW


Artificial Mulberry Diet powder for 20 Silkworms

Until now it has not been possible to rear silkworms without their natural foodplant Mulberry. Mulberry is often difficult to find but we are now able to offer a very convenient artificial diet that can be used as a substitute food, in any part of the world and at almost any time of the year, providing you can keep the silkworms at 25-28 degrees C. Eggs supplied in November/December will need to be refrigerated for 8-12 weeks before incubation.

The diet is sent as a sachet of powder that is easily prepared in the kitchen. It comes packeted to give sufficient food for the entire life of the silkworms, enough for 20 Silkworms. The powder can be kept for a year or more in a fridge. Made up diet can be refrigerated and kept for a month or more. Silkworms fed on diet will usually change to leaf if required, but if fed at first on leaf, they will not usually take to the diet. The life of a silkworm kept at the required temperature is about 5 weeks. 

Artificial diet takes a lot less time and trouble than rearing on leaf.  More importantly this enables rearing when Mulberry cannot be obtained. Eggs supplied in November - January will need to be refrigerated for 8-12 weeks before incubation. Rearing Silkworms is very educational and suitable for schools and families.

Complete MINI SILK FARM
Availability: NOW


THE MINI SILK FARM

A complete outfit for rearing silkworms from egg to cocoon, and reeling your own raw silk. Everything is provided: a small batch of eggs, food for the entire life of 20 silkworms, all the rearing equipment, detailed educational documentation and instructions, and a simple reeling device.

There is even a small bag of cocoons so that you can practise reeling, and don't have to wait to rear the cocoons from the egg.

Normally Silkworms feed on Mulberry leaves. This is an uncommon tree that is not always readily available, so we are providing a substitute food, which is a powder that comes with the necessary instructions for preparing the artificial diet in the kitchen. You will have a supply of fresh food always available for the silkworms throughout their life of about a month.

The Mini Silk Farm can be bought at any time of the year. The eggs are stored in a fridge until incubation. Although rearing in summer is easier because of temperature, you can rear silkworms almost throughout the year, if you can keep them at about 25º-28ºC. Eggs supplied in winter will need to be refrigerated for 8-12 weeks before incubation.

The instructions guide you through easy rearing, preparation of the artificial diet and the reeling process. The Mini Silk Farm is fun and unusually educational.

Macleay's Spectre (Prickly Stick Insect) Extatosoma tiaratum 10 eggs
Availability: NOW


Macleay’s Spectre or Australian Prickly Stick Insect Extatosoma tiaratum

This is one of the world’s most spectacular insects, and the female is reputed to be one of the heaviest insects on record, heavier than many birds! The male is slender and has large, folded wings. Female wings are vestigial.

Eggs usually hatch in spring and summer. Before hatching, keep the eggs in moist coir or peat compost at 10-20 degrees C. Keep eggs moist, not wet. Avoid mould.

Nymphs grow quickly in summer, becoming adults the following year. Feed on Bramble, Oak or Eucalyptus. Cages with netting sides or an aquarium are suitable. Change the food about 3 times a week, depending on temperature and how long the food is lasting.

These are hardy creatures, but they must be given regular care most days. They love having the foodplant sprayed! The adult females have a firm grip with spiny legs. If treated harshly they can retaliate! The males develop large wings and can fly across the room!

In winter Bramble and Eucalyptus are available. Keep the insects at living room temperature. Eggs are dropped loose on the cage bottom. They take months to hatch, and will sometimes do so even if the adults have not mated.

In all stages these are fascinating creatures and ideal for children, with adult supervision.

Peruvian Black Beauty Stick Insect Peruphasma schultei 10 eggs
Availability: NOW


Peruvian Black Beauty Stick Insect Peruphasma schultei,

These are unsuitable to send internationally but can be sent to GB addresses.

Only recently discoverd in Peruvian forest. You get adults of both sexes. Very attractive insects, easy to keep in a ventilated cage, feeding on Privet. They enjoy a spray most days with tepid water.

This species comes from just a small area in Peru and are not known from anywhere else. They are very special.

It is best not to let YOUNG children have the insects walking on their hands, because they have a defence mechanism that produces a pungent fluid when they are alarmed. Sometimes an irritant. You should wash hands after handling.

The insects are otherwise completely harmless. Their appearance in contrasting black and scarlet is an interesting example of colours that warn off predators.

Eggs are laid loose on the bottom of the cage.

European Swallowtail P.machaon gorganus 15 eggs or 10 larvae according to availability
Availability: NOW


European Swallowtail Papilio machaon gorganus 

Demand for eggs and larvae, for pupae (summer and winter) is so great that we are booking orders well in advance, which gives the best chance of ensuring availability.

Eggs are best kept in a clear plastic box without fresh foodplant. Newly hatched larvae need to eat their egg-shells. When they are ready for green food and wander from the egg shells, using a soft artist's brush, transfer to fresh foodplant. They do best sleeved on growing food, and this is strongly recommended, but can be reared in plastic boxes as long as always kept clean and with fresh food daily. See advice on using Plastic Rearing Containers on this website.

Easy to rear on Fennel and other Umbelliferae, such as carrot tops, Parsnip and Wild Parsnip flowers and fresh leaves. Very attractive caterpillar, bright green, striped black and orange. Double or even triple brooded.

This species is not suitable for beginners and schools.
