The ones that look like males, andromorphs, are usually under a third of the female population but the proportion can rise significantly and a theory that explains this response suggests that it helps overcome harassment by males. [7] Some Coenagrionid damselflies show male-limited polymorphism, an even less understood phenomenon. [8]
Calopterygidae is a family of damselflies, in the suborder Zygoptera. [2] They are commonly known as the broad-winged damselflies, [3] demoiselles, or jewelwings. [4] These rather large damselflies have wingspans of 50–80 mm (compared to about 44 mm in the common bluetail damselfly, Ischnura elegans), are often metallic-coloured, and can be differentiated from other damselflies by the ...
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the Epiophlebia damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and ...
Coenagrionidae is a family of damselflies, also known as pond damselflies, in the order Odonata and the suborder Zygoptera. [2] The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common. More than 1,300 species are in this family, making it the largest damselfly family.
Like the gigantic griffinflies, dragonflies lack the ability to fold their wings up against their bodies in the way modern insects do, although some evolved their own different way to do so. The forerunners of modern Odonata are included in a clade called the Panodonata, which include the basal Zygoptera (damselflies) and the Anisoptera (true ...
Calopteryx is a genus of large damselflies belonging to the family Calopterygidae. The colourful males often have coloured wings whereas the more muted females usually have clear wings although some develop male (androchrome) wing characteristics. In both sexes, there is no pterostigma. [1]
Endless Forms Most Beautiful was primarily inspired by the work of naturalist Charles Darwin. According to songwriter Tuomas Holopainen, the album's title is drawn from the last paragraph of Darwin's 1859 book On the Origin of Species which included the words "endless forms most beautiful" to describe evolution from one common ancestor to all living organisms: [8] [9]
The dainty damselfly is able to disperse quite widely so it is a possibility that a neighbouring population made its way back into the area. The current status of C. scitulum according to IUCN Red List is of 'Least Concern', meaning that the population is considered stable according to the IUCN's criteria. [1]
