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 ...
Monarchs are known to use their time-compensated sun compass during both the southern migration in the fall and the northern remigration in the spring. The change in directionality necessary to re-orient the monarchs has been shown to depend on the cold temperatures that the monarchs experience while overwintering in the coniferous forests of ...
Dragonflies are among the longest distance insect migrants. Many species of Libellula, Sympetrum and Pantala are known for their mass migration. [2] Pantala flavescens is thought to make the longest ocean crossings among insects, flying between India and Africa on their migrations. Their movements are often assisted by winds. [25] [26]
Common green darners migrate in fall and spring but for several reasons the southward movement in fall is more noticeable. [ 15 ] By attaching micro-radio transmitters to common green darners, researchers have found them to be capable of migrating up to 140 kilometres (87 mi) in a day, though they typically cover less distance per day.
The blue-eyed darner (Rhionaeschna multicolor, syn. Aeshna multicolor) is a common dragonfly of the family Aeshnidae; native to the western United States, it is commonly sighted in the sagebrush steppe of the Snake River Plain, occurring east to the Midwest from central Canada and the Dakotas south to west Texas and Oklahoma.
The end of winter doesn’t mean we’re done with wet weather, according to early spring forecasts by the Farmers’ Almanac. The almanac has been publishing long-range weather predictions and ...
Dragonflies also can specifically symbolize self-awareness, self-love and embracing your own personal power—and the abundance that reaching your potential can bring.
Dragonflies see faster than humans do; they see around 200 images per second. [80] A dragonfly can see in 360 degrees, and nearly 80 per cent of the insect's brain is dedicated to its sight. [ 81 ]
