Nannochoristidae (=Nannomecoptera) and Boreidae (=Neomecoptera) are traditionally assigned to the holometabolan Order Mecoptera. Both are presently in the focus of insect systematists. They differ strikingly from the "typical" mecopteran pattern, not only in their larval and adult morphology, but also in their life style and reproductive biology. Phylogenetic affinities between Boreidae ("snow fleas") and fleas were postulated mainly based on molecular data, and morphological characters related to food uptake and larval features suggest a close relationship between Nannochoristidae and true flies. Both groups display fascinating features such as preferred temperatures around 0°C, extremely slender larvae adapted to running water, and a highly unusual mating behaviour. Despite of the extremely low number of known species, there is no doubt that both groups are key taxa and in their own way highlights in the evolution of the extremely successful Holometabola. This and an impressive number of recent studies on various aspects of Nannochoristidae and Boreidae more than justifies a new volume in the series Handbook of Zoology dedicated to these highly unusual taxa.

Popular natural history periodicals in the nineteenth century had an incredible democratizing power. By welcoming contributions from correspondents regardless of their background, they posed a significant threat to those who considered themselves to be gatekeepers of elite science, and who in turn used their own periodicals to shape more exclusive communities. Making Entomologists reassesses the landscape of science participation in the nineteenth century, offering a more nuanced analysis of the supposed amateur-professional divide that resonates with the rise of citizen science today. Matthew Wale reveals how an increase in popular natural history periodicals during the nineteenth century was instrumental in shaping not only the life sciences and the field of entomology but also scientific communities that otherwise could not have existed. These publications enabled many actors—from wealthy gentlemen of science to working-class naturalists—to participate more fully within an extended network of fellow practitioners and, crucially, imagine themselves as part of a wider community. Women were also active participants in these groups, although in far smaller numbers than men. Although periodicals of the nineteenth century have received considerable scholarly attention, this study focuses specifically on the journals and magazines devoted to natural history.
