The great majority (80–99.99%) of individuals born do not survive to reproductive age, with perhaps 50% of this mortality rate attributed to predation. [1] In order to deal with this ongoing escapist battle, insects have evolved a wide range of defense mechanisms.
Phragmosis is any method by which an animal defends itself in its burrow, by using its own body as a barrier. [1] This term was originally coined by W.M. Wheeler (1927), while describing the defensive technique exhibited by insects. [2]
A worker can explode suicidally and aggressively as an ultimate act of defense, an ability it has in common with several other species in this genus and a few other insects. [1] The ant has an enormously enlarged mandibular gland, many times the size of other ants, which produces adhesive secretions for defense. [2]
The aphids form galls and act as colony defenders, at times sacrificing their own lives to do so. It has been shown that colony defense is more likely in habitats that are difficult to obtain and can hold a large number of individuals. [1] These gall locations are crucial because plants have a short window in which a gall can be produced. [1]
Autohaemorrhaging has been observed as occurring in two variations. [1] In the first form, blood is squirted toward a predator. The blood of these animals usually contains toxic compounds, making the behaviour an effective chemical defense mechanism. In the second form, blood is not squirted, but is slowly emitted from the animal's body.

Insects accordingly employ multiple defensive strategies, including camouflage, mimicry, toxicity and active defense. [138] Many insects rely on camouflage to avoid being noticed by their predators or prey. [139] It is common among leaf beetles and weevils that feed on wood or vegetation. [138] Stick insects mimic the forms of sticks and leaves ...
Lepidoptera antennae can be angled in many positions. They help the insect in locating the scent and can be considered to act as a kind of "olfactory radar". [6] In moths, males frequently have antennae which are more feathery than those of the females, for detecting the female pheromones at a distance. [7]
