Breeding
Old World swallowtails can easily be bred in captivity.
Butterflies can be lured to lay eggs in a backyard garden by keeping plenty of caterpillar food plants in it. Common rue plants are highly appropriate for this.
Once eggs or young caterpillars have been collected, they can be kept in a pot with holes on its top to allow air circulation. More than one caterpillar may be kept in a single pot since they do not attack each other (although they might sometimes get frightened by other caterpillars moving). They can be fed any of their food plants. Fennel is one of the easiest to find in the wild. Care must be taken with fennel as well as dill, though, because they will not eat hard, woody stems; they need to be fed the tender leaves. They can also be fed rue or milk parsley. Feeding them with unsuitable plants will lead to death from starvation.
Caterpillars are very fast eaters; they will spend their time eating or resting before they resume their eating again.
Once a sufficient size has been attained, they will attach themselves to any available structure with their silky threads. They will then stay still until they become pupae. This will take about a day.
Once in the pupa stage, they can be very carefully removed from the pot and placed in a warm location. The time the butterfly takes to form and come out depends on the temperature. If kept in warm summer temperatures, it will take about one or two weeks to form. On the other hand, if the temperature is lower, it might take as long as several months until it feels the weather is warm enough.
Pupae should not be kept on an impermeable surface, since when they eclose a bit of liquid will be released, this means the butterfly would stay wet and might not be able to fly. Absorbing paper such as the one used in kitchens is advisable.

Famous quotes containing the word breeding:
“The breeding we give young people is ordinarily but an additional self-love, by which we make them have a better opinion of themselves.”
—François, Duc De La Rochefoucauld (1613–1680)
“Not everyone knows how to be silent or to leave in good time. It happens that even people of good breeding fail to notice that their presence provokes in the weary or preoccupied host a feeling akin to hatred, and that this feeling is tensely concealed and covered up with lies.”
—Anton Pavlovich Chekhov (1860–1904)
“Good breeding ... differs, if at all, from high breeding only as it gracefully remembers the rights of others, rather than gracefully insists on its own rights.”
—Thomas Carlyle (1795–1881)
