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.

Pyjama Cage Standard  40 x 30 cm  height 50

Probably the most useful size as a general purpose cage. Suitable for breeding butterflies and moths, laying out pupae to emerge, keeping larvae that are large enough to cage, also for Stick insects and other creatures. Occupies little space. Can be stacked if required. This size is much lower in price and larger than the Flat-pack Wooden Framed Cage range, and much less costly to send.  

The cover can be washed by hand or machine, making your used cage like new for almost no effort, and no cost.

Pyjama Mini Cage 22 x 29 x 25cm high

This popular cage has just got even better. Nearly a third larger, and much improved dimensions.

Ideal as a beginner's cage, but also for the busy breeder who wants separate small cages. Excellent as an emerging cage for chrysalides and cocoons, ideal for keeping small numbers of larvae or other insects, when large enough for cage rearing.

This cage is suitable for laying out small numbers of pupae to emerge. Also for rearing smaller numbers of larvae or smaller larvae. Baby larvae should be first reared in plastic rearing containers or kept covered on growing food. Please see the note on the page for plastic rearing containers. This cage will hold small covered pots of plant, and larger sizes of cage are available for larger subjects.

When necessary the netting cover can be slipped off for cleaning or replacement. The Pyjama Mini cage is assembled in minutes and easily packed flat for winter storage. As the interest grows there are larger sizes available. For the experienced breeder the Mini Cage has many uses where a series of smaller cages is needed for separating species and giving different treatment.

The cover can be washed by hand or machine, making your used cage like new for almost no effort, and no cost.

Small Tortoiseshell Aglais urticae

The larvae live in tight clusters on the tips of nettle. If possible keep young larvae caged or in sleeves on growing nettle indoors or outside.

When the larvae have grown and need a lot of food, they can be kept in a cage on cut nettle in a jar of water. In a matter of weeks the pupae are formed hanging from the cage top, and the butterflies emerge in a little over a fortnight.

The butterflies can be kept in a cage for a few days, with plenty of flowers for nectar, and then released to help the wild populations. 

Peacock Butterfly (Inachis io)

Take advantage of this good season and help native butterfly species. Have the fun of watching them develop, pupate and hatch. Then release the butterflies to enhance the local butterfly population.

By late June, most orders will have been supplied. Further supplies depends on whether late breeding is successful. Orders will be booked and supplied as soon as, or if, available. Late orders will be booked for priority supply next season.

Young larvae should be started on growing nettle tips where they live in a tight cluster. When the larvae are larger, keep them caged on cut stems of nettle in a jar of water. Pupae are formed in a matter of weeks, hanging from the cage top. Butterflies emerge in about 3 weeks.  They can be kept for a few days in a cage with flowers for nectar, then released into the wild.

Peaock larvae need fresh nettle, growing if possible. Below we suggest a possible alternative, but growing nettle is the strongly recommended rearing method.

If you wish to rear the larvae in plastic boxes, while they are small, they can be kept on a lining of absorbent paper, with a sizeable sprig of fresh, un-wilted nettle. The paper lining must be changed and fresh food given EVERY day (including weekends). Place the previous day’s food with larvae on the new paper liner, add a fresh and adequate sprig of nettle, and the larvae will transfer themselves to the new food. Give them entire nettle stems with leaves, not leaves alone. Close the lid and keep the box out of sunlight. The closed container keeps the foodplant fresh. No holes are needed because there is more than enough trapped air for larvae to breathe. Never allow excessive condensation, nor mould. The size of box should be chosen according to the size and number of larvae being reared. The size 5 box is large enough to house them once they have grown for a week or two. For smaller larvae the Size 8 is appropriate. Rearing in a plastic container is only a temporary measure. Before the larvae become too large for the box, they should be kept in a cage, with the nettle kept fresh in a jar of water and changed daily. The pupae are formed hanging from the top of the cage and the foodplant. Even better is to sleeve the larvae on growing nettle. Be ready to move them to fresh food as soon as half the food supply has been eaten. Never leave moving the sleeve until most of the food has been consumed.

Lime Hawkmoth Mimas tiliae 

Extremely easy to rear on Lime or Elm. Other reported foodplants include Cherry, Alder, Birch, Oak, Hazel, Acer including Sycamore, Sorbus, Apple, Pear and Ash! In autumn the larvae will grow faster if kept warm.

The larvae do particularly well sleeved on growing foodplant but can be kept in plastic boxes or cages. Beautiful streamlined larvae. Larger larvae are often heavily marked with flame and scarlet spots and blotches. Very variable. They pupate underground. In captivity they will pupate amongst folds of cloth or absorbent tissue. Store pupae refrigerated for the winter. The moths normally emerge in May/June.

Eyed Hawk Smerinthus ocellata  

Fascinatingly camouflaged larvae which exactly match their leafy background. Easy to breed.

The larvae feed on Apple, Willows, Poplars. Other reported foodplants are Lime, Privet, Alder, Birch, Plum, Blackthorn, some Viburnums, Various Prunus, Laurel.

At pupation time, provide a container of compost to a depth of about 10cm, with a lid. The larvae burrow to pupate.  The moths, with vivid eye-spots, emerge the following spring.

Emperor Moth Saturnia pavonia 

Britain’s only Silkmoth. The male and female have similar markings, but the female is larger, and the male is more brightly coloured. The Emperor Moth occurs in many rural areas but is particularly found on heaths, where they breed on Heathers. Eggs are laid in clusters on the heather, looking just like the dead flowerheads from last year.

The larvae feed on a variety of plants, including Bramble, Raspberry, Hawthorn, Blackthorn, Apple, Plum, Blackthorn, Oak, Hornbeam, Birch, Heathers and Heaths, Blueberry, Meadowsweet, Wild Rose, Sea Buckthorn, Purple Loosestrife, Willows especially Osier Salix viminalis, Pussy Willow (Sallow). 

The caterpillars cluster in the early instars, eventually spreading out and becoming brightly coloured, as beautiful as such exotics as the Indian Moon Moth. The cocoon is spun in the foodplant. This is the stage that passes the winter.  An interesting construction with a neck and open end, through which the adult emerges in spring.  This is one of the fun species to rear.

Store cocoons in a cupboard until November. Then keep refrigerated until mid- February when they can be put in the emerging cage ready for hatching in March.

Chinese Silkmoth Antheraea pernyi  

Highly recommended for those who are looking for a spectacular moth, with LARGE exotic larvae: easily reared.  

This species used to be universally available. Over the years captive bred stocks have disappointingly become in-bred. We now have strong wild Chinese stock. s

A large species, and undoubtedly the best for beginners. Moths emerge in the spring. They pair very easily. 

Very easy to keep. Young larvae are black, and later turn green. They become enormous, feeding on  Oak, Birch, Sweet Chestnut, Horse Chestnut, Prunus, Hornbeam (Carpinus), Apple, Hawthorn, Beech, Osier Willow.  After about 2 months the larvae spin silk cocoons - an extra opportunity for a teaching project. Moths emerge the same year. Autumn larvae spin over-wintering cocoons.

Larvae thrive on Evergreen Oak when other plants not available. In winter, if the evergreen leaves are a bit leathery, make some incisions in the leaves with scissors. This releases attractive scent to the larvae and and gives them easier places to start feeding.

A PERFECT species for children and beginners!
