An English translation of this popular German handbook. Breeding Butterflies and Moths describes procedures for breeding. It may be assumed that whoever uses this book will also possess entomological works for identification. Therefore, the foodplants of the caterpillar are not Usted where this information has previously been well documented.
It is generally well known how many generations a species has a year. However, as this number can often be increased in captivity, this information could still be useful but is given here only for those species which regularly have only a single generation. Information given on the mmiber of generations obtained in nature, unless otherwise stated, refers to central Europe but is generally apphcable to the British Isles. When breeding is conducted under natural conditions in southern Europe, the different temperatiu*e and day-length can produce one or even two additional generations in many species.
Before Part II of the book is used. Part I must be read as it contains much detailed information not subsequently repeated. If instruction on the breeding of a particular species is needed, one looks first under the family, subfamily or genus where much of the required information is given; this can be supplemented if necessary by looking under the name of the species. It is of course possible to give detailed breeding advice only for some of the many European species of butterflies and moths.
