Madagascan Moon Moth mittrei 10 eggs
Availability: July

Madagascan Moon Moth Argema mittrei


Eggs of this huge Moon Moth are the largest we have ever seen. See the photo of one compared to other Giant Silkmoth eggs!

The larvae like warmth but not excessive temperature: likewise humidity but not too much. They feed well on Eucalyptus gunii, Rhus typhina and Rhus glabra. Also Liquidambar.

Huge netted cocoons of silvery silk – probably the biggest cocoon in the world! Both male and female moths are tailed but those of the male are very extreme.

This is a species that the connoisseur should not miss!

Alternative recorded foodplants include Willows, Lilac, Apple, Plum, Ash, Cherry and Tree of Heaven Ailanthus.  Atlas larvae like to browse on several foodplants and settle for the one or more that they like.


The larvae like warmth 25 -30 degrees C and humid jungle conditions, which are best achieved in a tank or plastic container, rather than a netting cage. Given these conditions the larvae are not difficult to rear, and spin cocoons in about 8 weeks from hatching.

Chinese Golden Emperor Loëpa oberthuri 15 eggs
Availability: June 2019

Chinese Golden Emperor Loëpa oberthuri

 Saturniid breeders will be familiar with Loëpa katinka but this rarity is a first for WWB. The moths are very large and splendidly adorned with wavy patterning, and bright colours. The larvae change with each instar,  becoming very large strikingly shaped and patterned, and fluffy. Best not to handle because the hairs can irritate sensitive skin.

Foodplants are Grape Vine, Virginia Creeper and Boston Ivy.  The larvae thrive sleeved outside in summer. The cocoon is tapered at the emergence end, and is best handled with care to avoid skin irriataion. Winter is passed as a cocoon. There may be two generations in a season if conditions in hot conditions. 


American Ailanthus Moth advena 15 eggs
Availability: Summer 2017

American Ailanthus Moth Philosamia cynthia advena 


Advena is the New World geographical race of this species which is otherwise found in Europe and right across Asia. 


This richly coloured moth in shades of olive and ochre, has become very difficult to obtain of late. This geographical race is richer in colouring and pattern than the European form.


The larvae thrive on Privet, Lilac, Ailanthus  and Osier Willow. On Privet advena can even be reared out of season.  


Gregarious when young, the larvae start yellow and change to powdery white, with black spotting. Usually single brooded, the moths emerge the following spring. Summer is the ideal time to rear advena and the larvae grow quickly even sleeved outside.




Neoris huttoni 15 eggs
Availability: Autumn 2018

Asian Huttoni Emperor Neoris huttoni Turkey

This is a large silkmoth that occurs from China, through India to Turkey. It is relatively unknown amongst entomologists.

The hibernating eggs are simply stored in the refrigerator until buds open in spring.

The larvae like Ash Fraxinus  in particular, Pear Pyrus, Plum and probably Cherry Prunus (Prunus padus is particularly successful), Willows Salix, Privet Ligustrum, Stag’s Horn Sumac Rhus thypina, Spirea.  [We have had a report of larvae not taking to Privet]

The larvae live beneath a leaf and do not like being disturbed. Young larvae go through interesting and different colour forms.

The cocoon is formed in litter on the ground. Moths emerge in autumn and lay overwintering eggs.

Our thanks to Dr. A. Pittaway for kindly letting us show some of his pictures of this rare species.

Antheraea yamamai 15  Eggs
Availability: Autumn 2018

Antheraea yamamai Japan and Central Europe


A rewarding and easy species to rear in spring. The eggs are stored cool for the winter. Bring them into room temperature when the buds open, and the larvae hatch in a couple of weeks or so. The caterpillar, a close relative of Antheraea pernyi, the Chinese Oak Silkmoth, grows very large. It has a green face and more interestingly, it spins a wonderful  egg-shaped cocoon of BRIGHT GREEN silk.  Very easy to rear on Oak. The larvae sometime take leaves of other trees and shrubs. Hawthorn is a early substitute for Oak. The pupa is spun in summer and does not emerge until well into autumn. Pairings are not difficult – resulting eggs overwinter.


The female moth is often bright canary yellow, with large ringed eye-spots, one in the centre of each wing. Colouring, especially in the male, is rather varied. Both sexes are illustrated with quite different colour forms.
