This book is dominantly about chemical defences of terrestrial arthropods, though other types of defences (camouflage, catapulting, sticky traps) are also mentioned. Chapters are short, and typically…
Defense by foot adhesion in a beetle (Hemisphaerota cyanea).

- 6 June 2000
The beetle Hemisphaerota cyanea (Chrysomelidae; Cassidinae) responds to disturbance by activating a tarsal adhesion mechanism by which it secures a hold on the substrate. Its tarsi are oversized and…

Experimental vein severance renders milkweed leaves edible to generalist herbivores that do not show vein-cutting behaviors and ordinarily ignore milkweeds in nature.
The chemistry of sexual selection.

The moth Utetheisa ornatrix (Lepidoptera: Arctiidae) is protected against predation by pyrrolizidine alkaloids that it sequesters as a larva from its foodplants, and females reinforce after copulation the choice mechanism they already exercise during courtship.
Defensive Secretions of Millipeds
- T. Eisner, D. Alsop, K. Hicks, J. Meinwald
- Biology
- 1978
The millipeds, comprising the arthropodan class Diplopoda, are an ancient group dating back to Devonian times, and they have held their own to this day, despite the evolutionary diversification of those very animals, the vertebrates, insects, and arachnids, that have come to include the primary predacious enemies of milliped.
Biparental defensive endowment of eggs with acquired plant alkaloid in the moth Utetheisa ornatrix.

- 1 August 1988
Field and laboratory tests showed that the alkaloids of Utetheisa ornatrix protect eggs from predators, and a previously identified pheromone, derived by the male from the alkAloid and emitted during precopulatory behavior, may announce the male alkaloidal worth to the female.
Ultraviolet Reflection of a Male Butterfly: Interference Color Caused by Thin-Layer Elaboration of Wing Scales
- H. Ghiradella, D. Aneshansley, T. Eisner, R. Silberglied, H. E. Hinton

The male of the butterfly Eurema lisa, like many other members of the family Pieridae, reflect ultraviolet light, but the female lacks such scales and is consequently nonreflectant.
Hindwings are unnecessary for flight but essential for execution of normal evasive flight in Lepidoptera
- Benjamin C. Jantzen, T. Eisner
- BiologyProceedings of the National Academy of Sciences
- 28 October 2008
It is reported that lepidopterans can still fly when their hindwings are cut off, but a procedure reducing their total wing surface by nearly one half causes them to incur a loss in both linear and turning acceleration, so that they are unable to exercise their normal flight maneuverability.

Seasonal Anointment with Millipedes in a Wild Primate: A Chemical Defense Against Insects?
- X. Valderrama, John G. Robinson, A. Attygalle, T. Eisner
- BiologyJournal of Chemical Ecology
- 1 December 2000
It is argued that the secretion that rubs off on the monkeys in the course of anointment provides protection against insects, particularly mosquitoes (and the bot flies they transmit) during the rainy season.
