Beetles: The Natural History and Diversity of Coleoptera
By Stephen A. Marshall
Firefly Books, 2018
784 pages, profusely illustrated, similar in style/quality to his other insect volumes.

In Beetles: The Natural History and Diversity of Coleoptera, Marshall has again applied his deep knowledge of the insect world. Comprehensive and packed with 27 pages of richly illustrated keys and 4,500 color illustrations, it provides the reader with a colorful and enjoyable introduction to the natural history of a huge group of organisms, along with an overview of the diversity of fascinating families included in the group. The subject of this book is an enormous one, since the beetles, or Coleoptera, include almost 400,000 named species.

Abstract

To aid the understanding of the role of insect herbivores as selective agents in the evolution of their host plants a survey of herbivore abundance and impact was undertaken in central Illinois on the six milkweed species: Asclepias incarnata, A. sullivantii, A. syriaca, A. verticillata, A. amplexicaulis, and A. tuberosa. These species occur in this order on a moisture gradient from wet to dry soil conditions. This survey revealed that 12 species occurred at an abundance of at least one individual per 100 host stems in 1 plot-year on one host species: Oncopeltus fasciatus*, Lygaeus kalmii*, Aphis nerii*, Labidomera clivicollis*, Tetraopes tetrophthalmus*, T. femoratus, T. quinquemaculatus, Rhyssomatus lineaticollis*, Danaus plexippus, Cycnia tenera*, Euchaetias egle and a leafminer. All but L. kalmii are specific to milkweeds in Illinois. Seven of these species, marked with asterisks, were abundant enough to act as major selective forces on the life history patterns of the milkweed species, populations and clones concerned.

Life history evolution in seven milkweeds of the genus Asclepias.

Abstract

Life history differences among seven species of Asclepias (A. exaltata, A. incarnata, A. purpurascens, A. syriaca, A. tuberosa, A. verticillata and A. viridiflora) in south-east Michigan are correlated with differences in microhabitat, in exposure to herbivores, and in competition. Components of each species' reproductive strategy include: number of stems per plants, number of umbels per stem, number of flowers and pods per umbel, number of seeds per pod, seed weight and annual increase in reproductive potential. Components of each species' selective regime include: the herbivore load (measured by the frequency of plants damaged by predators or animal parasites), competition (measured by the proportion of non-flowering plants and by the density of competitors), and environmental uncertainty (measured by annual mortality rates).

Survey of Coleoptera collected on the common milkweed, Asclepias syriaca, at one site in Ohio

Abstract

Coleoptera associated with the common milkweed, Asclepias syriaca L., were collected daily for 90 consecutive days. Of the 132 species listed, 18 were considered to be common (50 or more collected) while the majority of species were considered temporary visitors. The host specific milkweed beetle, [i]Tetraopes tetr

Abstract

In ecological restoration, habitat managers intervene in a degraded ecosystem to aid its recovery. To assess a restored habitat, one or more characteristics such as biodiversity, ecosystem functioning, and community structure are measured in relation to a reference habitat. While many restoration projects focus on vertebrates, arthropod taxa may be a more informative group, and beetles (Insecta: Coleoptera) in particular are a significant part of most ecosystem functions.
