Additionally, these insects tend to be relatively large, long-lived, active, and frequently aggregate. [2] Indeed, longer-lived insects are more likely to be chemically defended than short lived ones, as longevity increases apparency. [9] Throughout the arthropod and insect realm, however, chemical defenses are quite unevenly distributed.

The soldiers of the Neotropical termite family Serritermitidae have a defense strategy which involves front gland autothysis, with the body rupturing between the head and abdomen. When outside the nest they try to run away from attackers, and only use autothysis when in the nest to block tunnels up, preventing attackers entering.
Plants have evolved many defense mechanisms against insect herbivory in the 350 million years in which they have co-evolved.Such defenses can be broadly classified into two categories: (1) permanent, constitutive defenses, and (2) temporary, inducible defenses. [1]
The story hinges on standardized testing in middle-grade schools, a matter of contemporary controversy. [2] Teachers in a local middle school have been accused of cheating on the test, and Theodore Boone becomes involved. As he and his eighth-grade classmates are also being tested, the fairness of the test is of particular concern to him.
