Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
The hygric hypothesis proposes that the discontinuous release of CO 2 is an adaptation that allows terrestrial insects to limit respiratory water loss to the environment. [5] This hypothesis is supported by studies that have demonstrated that respiratory water loss is substantially higher in insects forced to keep their spiracles open, than ...
Insect ecology is the interaction of insects, individually or as a community, with the surrounding environment or ecosystem. [1] This interaction is mostly mediated by the secretion and detection of chemicals ( semiochemical ) in the environment by insects. [ 2 ]
Insects were once believed to exchange gases with the environment continuously by the simple diffusion of gases into the tracheal system. More recently, large variation in insect ventilatory patterns have been documented, suggesting that insect respiration is highly variable.
Insects draw air into their bodies through spiracles, holes found along the sides of the abdomen. These spiracles are connected to tracheal tubes where oxygen can be absorbed. All aquatic insects have become adapted to their environment with the specialization of these structures Aquatic adaptations. Simple diffusion over a relatively thin ...
This adaptation allows them to hide within their environment because of a resemblance to the general background or an inedible object. [2] When an insect looks like an inedible or inconsequential object in the environment that is of no interest to a predator, such as leaves and twigs, it is said to display mimesis, a form of crypsis.
Insect evolution is characterized by rapid adaptation due to selective pressures exerted by the environment and furthered by high fecundity. It appears that rapid radiations and the appearance of new species, a process that continues to this day, result in insects filling all available environmental niches.
The Phasmatodea (also known as Phasmida or Phasmatoptera) are an order of insects whose members are variously known as stick insects, stick bugs, walkingsticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles , although this name is shared by both dragonflies and crane flies. [ 1 ]
