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 ...
Anopheles mosquitoes can fly for up to four hours continuously at 1 to 2 km/h (0.62 to 1.24 mph), [8] traveling up to 12 km (7.5 mi) in a night. Males beat their wings between 450 and 600 times per second, driven indirectly by muscles which vibrate the thorax.
Insects that live under the water have different strategies for dealing with freezing than terrestrial insects do. Many insect species survive winter not as adults on land, but as larvae underneath the surface of the water. Under the water many benthic invertebrates will experience some subfreezing temperatures, especially in small streams.
The mosquito larvae will live in the pitcher plant until it goes through its fifth instar about 20 to 22 days after hatching. They then emerge as adult mosquitoes ready to mate. Wyeomyia smithii females will produce a clutch of fertilized eggs generally within two days of sexual maturity.
An individual mosquito can be heard across 2–5 cm in distance when sound level rises to 22-25 dB. [7] Male and female mosquitoes can also be distinguished by their wingbeat frequencies, which are 700–800 Hz for males and 400–500 Hz for females. [7] As a result, flight sounds are used to determine flight activity and distinguish sex of groups.
