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.

Abundance of herbivores on six milkweed species in Illinois.

Price, P.W. & M.F. Willson. 1979. Abundance of herbivores on six milkweed species in Illinois. American Midland Naturalist 101(1): 76–86.

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.
