If you are a beginner and need information on rearing from small caterpillars, or hatching out pupae, please order the All Colour Paperback BUTTERFLIES. INSTRUCTIONS ARE NOT SENT WITH EACH SPECIES, you need to acquire basic skills and this book is a simple way of doing so. Please read the Plastic Rearing Container section for advice on rearing young caterpillars which must have nursery treatment while they are not large enough to be kept in cages. This information is enlarged upon in the paperback guide referred to above.

We do not invoice: please use school or personal credit card to order on this website, and reclaim with the invoice printed from your account.Thank you.

MAGICAGE 30cm cube
Availability: NOW


MAGICAGE

This is an innovative design.

The cage is folded absolutely flat. Pull on the centre fold and it forms an instant 30cm cube with netting on all panels, except for one which is clear plastic. This can be used as a waterproof base or as a side observation panel. Access is via a rounded zip in one netting side.

Ideal for laying out pupae to emerge. You can keep larvae or stick insects on jars of cut food. But the multitude of uses becomes more apparent as you try out new methods.
 

With the cage positioned over a growing plant you can feed and breed butterflies. The cage can be used as a sleeve on the branch of a tree.

Keep butterflies on cut flowers.

Use the Magicage for hibernating butterflies. Breed Silkmoths and Hawkmoths in the Magicage.

There has probably never been such a versatile cage.

Once you start using the Magicage, you may wish you had thought of having more of them!

Artificial Mulberry Diet for 20 Silkworms
Availability: NOW


Artificial Mulberry Diet 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 in two sizes that give sufficient food for the entire life of the silkworms, enough for 20 and 50 Silkworms. The powder can be kept for a year or more in a fridge. Made up diet can be refrigerated and kept for some eight weeks. The life of a silkworm kept at the required temperature is about 5 weeks. (If you buy a collection of 6 named races please remember you need food for 6 times the number of eggs bought)

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.

Small Tortoiseshell Aglais urticae 10 larvae
Availability: NOW


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 10 larvae
Availability: August


Peacock Butterfly (Inachis io)
The Peacock Butterfly normally produces only one generation in Britain and northern Europe. In a good year it is sometimes possible to produce a second generation in August, and that is our hope and intention this season.

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.

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.

Five Painted Lady larvae in Total Environment Pot

POSTAL DELAYS At present Royal Mail is under pressure due to the Covid 19 crisis. Please be patient if your order takes more days than usual and please refrain from expressing anger if the delay has caused loss of livestock.     Everyone is doing their best!   Thank you.

The five Painted Lady caterpillars live their whole life inside the see-through pot which contains all they need from birth to pupating. You need add no food. You don’t even clean them out and they look after themselves over weekends!

The larvae grow quite quickly in summer indoor conditions (never keep them in direct sunshine).  The container is easily passed round a group without disturbance to the larvae.
During skin change the larvae do not move or eat This may last a day or two.

Don't be alarmed by this: it is a natural stage in their development.

When the larvae have finished eating, they suspend themselves from a silk pad spun on special absorbent paper in the lid. Here they cast their caterpillar skin.  If you are lucky and look at the right moment you can see the actual moment of change from caterpillar to chrysalis.

Let the chrysalis harden for a couple of days, then hang the paper pinned inside a cage for the butterflies to emerge.

You can keep the butterflies for a few days in a cage with nectar flowers. Then, except in the colder months October to March, release them into the wild where they may breed naturally in your area. Please keep the larvae and pupae in an even room temperature (around 18-22º) day and night. Keep away from direct sunlight or a direct heat source such as a radiator.

The instructions are printed above - please note them for the arrival of the larvae which are not sent with further instructions. If you are sending larvae as a present, please remember the recipient will not have these instructions, unless you copy them to the recipient.

 

Can be ordered in advance. During the season there may be a delay of a couple of weeks or more if larvae are not currently at the size for sending.

Painted Lady Vanessa cardui
Orders will be sent feeding on diet instead of leaf. This means they travel better in the journey by post, and they can be changed to leaf on arrival.

POSTAL DELAYS At present Royal Mail is under pressure due to the Covid 19 crisis. Please be patient if your order takes more days than usual and please refrain from expressing anger if the delay has caused loss of livestock.     Everyone is doing their best!   Thank you.

The Painted Lady butterfly occurs in more continents of the world than any other butterfly. The larvae are easy to rear on Thistle (its preferred food plant), Burdock, Stinging Nettle, Mallow, Hollyhock and will often take other foodplants. 

Each larva lives solitarily from birth. It spins a protective silk cover, living at first off the leaf cuticle. When possible, keep the larvae on a growing foodplant, which enables the caterpillar to make its silk cover, and move on to fresh food when it requires. If kept on cut food, please ensure that the plant is kept fresh and changed before the quality of the food suffers. This of course applies to all species, but the method has to take into account the solitary habit of the larva, and its protective silk. The best way is to enclose pot and foodplant in a sleeve. The WWB zipped sleeves make this a very convenient rearing method.

Depending on temperature, the larvae pupate in a little over a month. Butterflies emerge in 2-3 weeks. The cycle continues throughout summer and several broods are possible in a season.

The butterflies can be kept with nectar flowers for some days, and then except in the colder months October to March, released to breed in the wild.

There may be a delay of a couple of weeks if larvae are not at the right size for sending. Can be ordered immediately.

Larvae are often quite small when sent. Too small  to be put into a cage or aquarium. They are best reared on growing foodplant, enclosed in a sleeve. Alternatively keep in a plastic box, lined with absorbent paper, and changed daily. For details see the All Colour Paperback BUTTERFLIES.

Comma larvae c-album 10 larvae
Availability: NOW


Comma Butterfly Polygonia c-album   

Fascinating larvae with curious half and half markings in black, brown and white, mimicking a bird dropping. The larvae feed on Stinging Nettle, Elm and Hop. Also Sallow, Osier Willow Salix viminalis, and sometimes other Willows. They live singly. Fast growing.

Young larvae will succeed best if placed on growing foodplant. Enclose plant and pot in a netting sleeve, tied at both ends: size 3 is ideal. Otherwise you can sleeve Comma larvae on branches of Elm, Sallow and Willows, including Osier. Good ventilation is required. Cut food is not recommended at least until the larvae are nearly half grown. Comma larvae do not like crowding, and do best kept so that each caterpillar can get away and live on its own. Disease can occur if conditions are not perfect. If it does, it helps that the larvae live separately. Any infected or dead larvae should be removed and disinfection should be carried out, lightly spraying 10% bleach solution, which will not affect healthy larvae, but does help prevent the spread of disease.

This garden butterfly is capable of re-colonising places where it used to be. In autumn the butterflies are very partial to fallen fruit. With some help this butterfly could be encouraged to spread.

Keeping two species of larvae together on the same foodplant?  It is sometimes possible, but their way of life may differ and we recommend keeping them separately.  Comma larvae live solitary lives and should be reared in their own enclosure.

Emperor Moth pavonia 15 eggs
Availability: Spring 2021


Emperor Moth Saturnia pavoni

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.
