Editing Bombyx mori (section)

== Types ==
Mulberry silkworms can be divided into three major categories based on seasonal brood frequency. Univoltine silkworms produce only one brood a season, and they are generally found in and around Europe. Univoltine eggs must hibernate through the winter, ultimately cross-fertilizing in spring. Bivoltine varieties are normally found in East Asia, and their accelerated breeding process is made possible by slightly warmer climates. In addition, there are polyvoltine silkworms found only in the tropics. Their eggs typically hatch within 9 to 12 days, meaning there can be up to eight generations of larvae throughout the year.<ref>{{cite web|last=Trevisan|first=Adrian|title=Cocoon Silk: A Natural Silk Architecture|url=http://www.senature.com/research/publications/cocoon-silk-a-natural-architecture|publisher=Sense of Nature|url-status=dead|archive-url=https://web.archive.org/web/20120507085636/http://www.senature.com/research/publications/cocoon-silk-a-natural-architecture|archive-date=7 May 2012}}</ref>
