The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
Various patterns of behavior enable certain ectotherms to regulate body temperature to a useful extent. To warm up, reptiles and many insects find sunny places and adopt positions that maximise their exposure; at harmfully high temperatures they seek shade or cooler water. In cold weather, honey bees huddle together to retain heat.
The honey bee, for example, does so by contracting antagonistic flight muscles without moving its wings (see insect thermoregulation). [ 18 ] [ 19 ] [ 20 ] This form of thermogenesis is, however, only efficient above a certain temperature threshold, and below about 9–14 °C (48–57 °F), the honey bee reverts to ectothermy.
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Dragonflies also use postural thermoregulation to increase body temperature. Keeping the flight muscles in the thorax warm is especially important, since otherwise the insect cannot fly. Dragonflies may position their wings to reflect sun onto themselves, or, if they are perched on a warm surface, to form a "greenhouse" over the thorax.

A typical flyswatter. A flyswatter (or fly-swat, fly swatter [1]) usually consists of a small rectangular or round sheet of a lightweight, flexible, vented material (usually thin metallic, rubber, or plastic mesh) around 10 cm (4 in) across, attached to a handle about 30 to 60 cm (1 to 2 ft) long made of a lightweight material such as wire, wood, plastic, or metal.
Dryocampa rubicunda, the rosy maple moth, is a small North American moth in the family Saturniidae, also known as the great silk moths.It was first described by Johan Christian Fabricius in 1793.
