As most work on flower foraging focuses on bees, studying Lepidoptera can offer fresh perspectives on how sensory capabilities shape the interaction between flowers and insects. Through a combination of innate preferences and learning, many Lepidoptera persistently visit particular flower species. Butterflies tend to rely on their highly developed sense of colour to locate rewarding flowers, while moths have evolved sophisticated olfactory systems towards the same end. However, these modalities can interact in complex ways; for instance, butterflies’ colour (...) preference can shift depending on olfactory context. The mechanisms by which such cross‐modal interaction occurs are poorly understood, but the mushroom bodies appear to play a central role. Because of the diversity seen within Lepidoptera in terms of their sensory capabilities and the nature of their relationships with flowers, they represent a fruitful avenue for comparative studies to shed light on the co‐evolution of flowers and flower‐visiting insects.

Drawing heavily upon natural history data from the Neotropical butterfly fauna, an attempt is made to develop a model, with testable hypotheses, to account for the evolution of egg-clustering and larval gregariousness. Given the high diversity of both plant and butterfly species in the American tropics, there is a higher incidence of egg-clustering there, including some species with aposematically-colored immature stages. Emphasis is placed on the need to examine both the physical (mechanical) toughness of larval food plants for larval feeding (...) success, and the spatial structuring of food plant populations. It is argued that when food plant spatial patchiness is high, the breadth of local food plant species usage low, plant growth rates high, fed-upon structures tough, butterfly dispersal low, and reproductive potential low, egg-clustering evolves. Such ecological character states, coupled with the occurrence of food plant patches in large sizes relative to the nutritional and fecundity needs of the butterfly specialist on the species, select for egg-clustering to ensure survival of the butterfly population in that habitat. It is emphasized that the model proposed here requires considerable examination through field studies. (shrink)

Focused on the material practices of making insect specimens, I explore how shifting concepts of potential are intricately crafted on the lab bench. Different types of time—from personal histories to imagined futures—are created and entangled as butterflies are made into specimens. Transforming a butterfly into a scientific tool does not merely transform the butterfly, I suggest, but also reciprocally folds back to transform the scientist who makes it. Based on ethnographic fieldwork with scientists in the labs and workrooms at the (...) Smithsonian National Museum of Natural History in Washington, DC and the California Academy of Sciences in San Francisco, California, I follow butterflies and moths (Lepidoptera) as they are collected, euthanized, pinned, genetically sampled for rewilding projects, such as reviving a Californian sand dune ecology, and frozen in biobanks for as-yet-unknown future uses. Through a comparative study of practices at these two sites, I examine how a butterfly can contain multiple types of potential: manifesting its inherent potential as it transforms from caterpillar to butterfly, the plasticity of the butterfly body as it is crafted into a scientific specimen, and the potential of that specimen to be used as a site for extracting genomic data. Perceptions of time, salvation, loss, and care emerge as specimens are prepared, sampled, and reimagined as solutions for recreating lost ecologies. (shrink)

This paper integrates genetical studies of variation in the wing patterns of Lepidoptera with experimental investigations of developmental mechanisms. Research on the tropical butterfly,Bicyclus anynana, is described. This work includes artificial selection of lines with different patterns of wing eyespots followed by grafting experiments on the lines to examine the phenotypic and genetic differences in terms of developmental mechanisms. The results are used to show how constraints on the evolution of this wing pattern may be related to the developmental (...) organisation. The eyespot pattrn can be envisaged as a set of developmental homologues; a common developmental mechanism is associated with a quantitative genetic system involving high genetic correlations. However, individual genes which influence only subsets of the eyespots, thus uncoupling the interdependence of the eyespots, may be important in evolutionary change. The postulated evolutionary constraints are illustrated with respect to differences in wing pattern found among other species ofBicyclus. (shrink)

To believe in fairies is not to believe in rare Lepidoptera or the like, within a basically materialistic context. It is to take folk?stories seriously as accounts of the ?dreamworld?, the realm of conscious experience of which our ?waking world? is only a province, to acknowledge and make real to ourselves the presence of spirits that enter our consciousness as moods of love or alienation, wild joy or anger. In W. B. Yeats's philosophy fairies are the moods and characters (...) of human life, conceived not as alterations in a material being, but as the spiritual rulers of an idealistically conceived world. Yeats follows folklore in making them ambivalent: either the sweet undying voices of nature or the disillusioned destroyers of humane life. His prophecies of a New Age were of a world ruled unknowingly by fairies, spirits invoked by music, poetry, and love, that do not necessarily take much care of ordinary human life. The ?Fairy Faith? described by Yeats and Evans?Wentz is a variety of idealism, and by no means absurd. (shrink)

The structure of Russian science of the XIX century was dominated by state forms of its organization. At the same time, there were also a few private (non-governmental) forms of research communities. One of the little-studied phenomena of scientific privacy is the so-called “kruzhok” (a little circle in Russian). The article examines the history of the formation and activity of one of such “kruzhoks”, formed in the 1880s–1890s around Grand Duke Nikolai Mikhailovich, who was seriously engaged in research in the (...) field of lepidopterology (the branch of entomology studying butterflies, Lepidoptera). The role and significance of this “kruzhok” for the development of descriptive entomology in the situation of its weak institutionalization in Russia at the end of the XIX century are briefly considered, the course of scientific research of the Grand Duke and his entourage and the reasons for the termination of their activity are discussed. The history of this informal association is interpreted by us as a manifestation of the purposeful life-making of the Grand Duke, who thus tried to professionalize his hobby and enter the scientific community of entomologists on an equal footing, without breaking with his social environment and without going beyond the behavioral norms established by society for persons of his status. It is shown that the Nikolai Mikhailovich’s “kruzhok” became not only an instrument of his life-making, but also an influential center of Russian lepidopterology, the development of which was thereby given a powerful impetus.

Bernard d’Abrera’s concise atlas of the world’s butterflies is a beautifully produced book with the most stunning photographs of butterflies that I’ve ever seen. Though not intended as a coffee-table book, it could eminently serve that purpose. D’Abrera himself is a world-renowned butterfly and moth expert at the British Museum (Natural History) in London. Over the years he has produced books on the lepidoptera indigenous to various regions of the world. This book provides a synopsis of his life’s work.

From the 1950s to the 1970s, a group of physician–researchers forming the ‘Liverpool school’ made groundbreaking contributions in such diverse areas as the genetics of Lepidoptera and human medical genetics. The success of this group can be attributed to the several different, but interconnected, research partnerships that Liverpool physician Cyril Clarke established with Philip Sheppard, Victor McKusick at Johns Hopkins University, the Nuffield Foundation, and his wife Féo. Despite its notable successes, among them the discovery of the method to (...) prevent Rhesus haemolytic disease of the newborn, the Liverpool School began to lose prominence in the mid-1970s, just as the field of medical genetics that it had helped pioneer began to grow. This paper explores the role of partnerships in making possible the Liverpool school's scientific and medical achievements, and also in contributing to its decline. (shrink)
