Describes the physical characteristics, behavior, and life cycle of the silkworm moth, and how its cocoon is used to make silk.

An introduction to the domesticated silkworm moth, raised on farms in Japan and elsewhere for the sake of the silk thread out of which its cocoons are constructed.

Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and general nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the milligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques find their way into the classroom when the problems involved have been suffi ciently ironed out to permit students to master the manipulations in a few lab oratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomo logical problems, and (3) to describe experiments which may be applicable for use in biology laboratory co~rses.

The Decision Between Us combines an inventive reading of Jean-Luc Nancy with queer theoretical concerns to argue that while scenes of intimacy are spaces of sharing, they are also spaces of separation. John Paul Ricco shows that this tension informs our efforts to coexist ethically and politically, an experience of sharing and separation that informs any decision. Using this incongruous relation of intimate separation, Ricco goes on to propose that “decision” is as much an aesthetic as it is an ethical construct, and one that is always defined in terms of our relations to loss, absence, departure, and death. Laying out this theory of “unbecoming community” in modern and contemporary art, literature, and philosophy, and calling our attention to such things as blank sheets of paper, images of unmade beds, and the spaces around bodies, The Decision Between Us opens in 1953, when Robert Rauschenberg famously erased a drawing by Willem de Kooning, and Roland Barthes published Writing Degree Zero, then moves to 1980 and the “neutral mourning” of Barthes’ Camera Lucida, and ends in the early 1990s with installations by Felix Gonzalez-Torres. Offering surprising new considerations of these and other seminal works of art and theory by Jean Genet, Marguerite Duras, and Catherine Breillat, The Decision Between Us is a highly original and unusually imaginative exploration of the spaces between us, arousing and evoking an infinite and profound sense of sharing in scenes of passionate, erotic pleasure as well as deep loss and mourning.

Describes the physical characteristics, habits and stages of development of silkworms, as well as how they are raised to produce silk.

The Matter of History links the history of people with the history of things through a bold new materialist theory of the past.
