Invertebrates butterfly

Butterflies are fascinating insects and easy to observe in the field. They belong to the Lepidoptera family, a word of Greek origin meaning 'wings with scales', which includes both daytime butterflies and moths or nighttime butterflies.

  • Butterflies are fascinating insects and easy to observe in the field. They belong to the Lepidoptera family, a word of Greek origin meaning 'wings with scales', which includes both daytime butterflies and moths or nighttime butterflies.
  • It is these wings full of pigmented and reflective scales that give the butterflies their spectacular and striking colour. Besides being so pleasant to observe, these colours play a very important role in the reproduction and survival of butterflies.
  • According to the latest research, the colours of butterflies are the product of small structures in the wings, called gyros, which refract sunlight like a prism. And, believe it or not, it turns out that only one gene is responsible for regulating these rich colour patterns, as demonstrated in a study published in the Proceedings of the National Academy of Sciences (PNAS) in 2017.
  • The researchers used the CRISP/Cas gene-editing technique to inactivate the gene and observe changes in the colouration of the butterfly's wings. What they observed is that this gene, called WntA, is the same for all butterfly species, but it works differently in each species and even expresses itself in different areas of the wings: sometimes in the veins and sometimes at the base of the wings.
  • Butterflies are fascinating and we are discovering more and more amazing things about them. For example, a recent study published in Frontiers in Ecology and Evolution in 2016 found that the butterfly species Graphium Sarpedon has fifteen types of photoreceptors in its eye, a record in the world of insects and which allows it to detect a variety of different colours.

Monarch butterfly She's definitely the queen of all butterflies. The monarch butterfly (Danaus plexippus), native to Central and North America, is known for its large size and spectacular migrations, among the longest described in the insect world.

Transparent butterfly The image of the transparent butterfly (Greta oto) speaks for itself. This species belongs to the family Nymphalidae and is native to Central America.

Zebra Butterfly The zebra butterfly (Heliconius charithonia) is a sedentary species of butterfly that lives in Florida and South Texas.

Peacock butterfly The peacock butterfly (Inachis io) likes, in spring, to feed on willow flowers, so this is a good tree to get close to in order to try to see one of these butterflies so spectacular and present all over the European continent.

Lithium Butterfly This beautiful butterfly (Apatura iris) lives in deciduous forests in much of Europe. As a curiosity, we should point out that the males of this species are attracted by smells as unpleasant to us as sweat, human excrement and reheated tar.

Elizabethan butterfly The Elizabethan butterfly (Graellsia isabellae) was named after its discoverer, Mariano de la Paz Graells, in honour of Queen Elizabeth II of Spain. This nocturnal butterfly is considered endemic to the Iberian Peninsula, although isolated populations are found in other European mountains, which may have been introduced.

The glory of Bhutan This spectacular butterfly (Bhutanitis lidderdalii) lives in Bhutan, certain areas of northern India and South-East Asia.

The chimera with bird's wings Chimpanzee Ornithoptera lives in the mountains of New Guinea. Its scientific name, which would come to mean something like "chimera with bird wings" refers to the appearance of the males this spectacular species of butterfly.

The big marble Euchloe ausonides lives in western North America. Its population is highly threatened and has been suffering a continuous decline since the 1980s.

La chupaleche This butterfly (Iphiclides podalirius) is one of the largest in Europe but is becoming increasingly rare, probably due to agricultural practices. Adults are attracted to nectar-rich trees and shrubs.
