Tiger Swallowtail glaucus 15 eggs or 10 larvae
Availability: July/August



Tiger Swallowtail Papilio glaucus North America 15 eggs or 10 larvae according to availability

The Tiger Swallowtail is perhaps North America’s grandest swallowtail. As a curiosity, a small proportion of females emerge as melanics, not as beautiful as the typical female, but different! They can be bred in captivity and the larvae are as exotic as many of the tropical swallowtails, with the Papilio eye markings and bird dropping camouflage in the early instars. Try feeding them on Cherry or Lime, and they will probably take a wider variety of foodplants. These have been reported: Ash, Cherry, Tulip Tree Liriodendron, Magnolia, Birch, Poplar, Prunus, Apple, Willow, Alder.

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.

Swallowtail Papilio machaon machaon Sweden 15 eggs or 10 larvae according to availability
Availability: July


Swallowtail Papilio machaon machaon Sweden

It is extremely rare to get breeding stock of the Swedish nominate race, and this is a great opportunity for breeders! Numbers already low1

This is the nominate subspecies. Papilio machaon machaon Linné 1758. Both the pupae and adult butterflies more resemble those of britannicus than the main European subspecies gorganus.

These pupae have been specially bred for us from wild stock in Sweden. Locality Date Vindåsens (57º 5452’ N and 16º 4702 E) on the east coast of Sweden, 10 yards from the sea. Here Parnassius apollo and Poplar Admiral were also seen at the same time.

We consider them to be very close to the English Swallowtail in behaviour and rearing characteristics, even though they are not confined to wetlands. 

The larvae do well on both wild and garden Parsnip and, like the English Swallowtail,  Milk Parsley Peucedanum palustre and P. ostruthium. Also  Angelica archangelica. Carrot tops may also be tried. The larvae will eat Fennel but it appears that mortality of machaon machaon is higher on Fennel than the preferred foodplants.

There is normally only one generation in the year. Some pupae might be encouraged to emerge in late summer, but most will be stored cool until November, then refrigerated until April in anticipation of May emergence.

Citrus Swallowtail POT LUCK collection of 20 eggs
Availability: NOW


Citrus Swallowtail POT LUCK collection of 20 eggs

This is great fun! You get 20 unidentified eggs that have been laid on Citrus plants in the butterfly house. They might be just one species but are much more likely to be mixed species.  Examples could include demoleus, polytes, bianor, rumanzovia,  memnon and other related species.

To rear these ideally you need potted Citrus trees in a greenhouse or somewhere you can keep warm and moist. The larvae are likely to accept substitutes such as Choisya and Skimmia.

The larvae develop fast in warm conditions, usually taking no more than 4 weeks from egg to adult, though some of the larger ones need a little longer.

Citrus larvae undergo a number of colour changes through the different instars, starting camouflaged as a bird dropping, but later taking on startling pattern with prominent eye-spots, in shades of green, with beautiful markings.

Don’t miss these – they are real fun!

Clouded Yellow Crocea 10 Larvae
Availability: Summer


Clouded Yellow Butterfly Colias crocea 

This butterfly migrates and is not resident in Britain. Restrictions on travel have made it difficult to obtain sufficient breeding stock, so there is quite a waiting list. Adequate supplies in 2021 will depend on the ability to travel to obtain breeding stock.

A great favourite with entomologists and easy to rear on potted Clover. The easy way is to enclose the whole pot in a sleeve size 3. The larvae grow fast and will produce butterflies very quickly, particularly in warm conditions.

Small Tortoiseshell Aglais urticae 10 larvae
Availability: Summer


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.

Painted Lady cardui 10 larvae
Availability: NOW


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: June/July


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.

Beckeri Marsh Fritillary Euodrydryas beckeri 10 larvae
Availability: Spring 2022


Beckeri Marsh Fritillary Euodrydryas beckeri  Now considered as a species separate from aurinia.

This is the most magnificent form of the Marsh Fritillary – very large, boldly marked and the brightest colouring and pattern of all. Beckeri occurs in parts of Spain, Portugal and North Africa. This stock is from Portugal. The larvae feed on Honeysuckle. In the wild these hibernate. It may be possible to keep summer larvae warm and with longer day length to get them to develop and produce butterflies again the same year. This has not yet been tried.

IRISH Marsh Fritillary aurinia Egg Batch
Availability: May


Irish Marsh Fritillary Eurodryas aurinia

Very hard to obtain: some available NOW!

We are taking orders now for whole egg batches of Irish Marsh Firtillary, for delivery in May/June. To rear these you need growing plants (potted or wild) of Devil’s Bit Scabious. The larvae also feed on Honeysuckle. Normally the larvae form a web in which they pass the winter. It may be possible to keep them warm and produce butterflies this year, but this should only be attempted by experienced breeders.
