The 10 smallest insects in the world
The class of insects corresponds to the most diverse group of animals on the planet, within which one million identified species are located, with many millions more to be described. These animals managed to colonize a large number of ecosystems, developing multiple forms of adaptation that facilitate their dissemination.
This is a species of Wasp in the order Hymenoptera, which is specifically distributed in North America. Without a doubt, it is among the smallest adult insects in the world, as its length varies between 0.139 and 0.240 millimetres.
It is a parasitic insect that spends most of its life inside the eggs of its host, which is the shell louse.
In this case, we have another type of Wasp, one of the smallest flying insects in existence. Although there are other species within this genus, this is the smallest of the group. It has dimensions between 0.181 and 0.224 mm . Furthermore, it is located in tropical and subtropical regions.
This is a species of beetle, considered one of the smallest insects in the world. It belongs to the Ptiliidae family, which includes several small beetles. It has an elongated body and an oval shape. So far, the smallest individual identified was 0.325 mm and, in general, they have an average dimension of 0.338 mm.
Despite its size, it is not a parasitic animal, feeding on fungal spores of the Basidiomycota group. Initially, it was located in Nicaragua, but it was also found in Colombia.
Within this group of tiny insects, we must also include a member of the order Diptera, which is the smallest flight described. Its size is undoubtedly surprising when compared to other species of flies. The dimension it usually attains is 0.4mm and it is native to Asia.
In the larval stage, it is parasitic, feeding on the inner tissue of the ants’ heads where eggs are deposited.
Here we do not find a single insect, but it is a group of beetles characterized by their tiny size. They are included in the family Curculionidae and they are distinguished by feeding on vegetable matter, for which they use a chewing mouth.
In many cases, several species become pests due to the damage they can cause. For example, in crops. Some species measure 0.5 mm What Hypothenemus Hampei and others reach 1 cm, for example, the hollyhock weevil ( Lixus pulverulentus ).
This is an insect in the Formicidae family, which includes the ants . In this case, we have the smallest species in the group, which depending on the country can be named in different ways. It is considered one of the most harmful invasive alien species in the world, having a wide distribution in America, Africa and Oceania.
They are golden or light brown ants measuring an average of 1.5 millimeters in size . Despite its small size, it is capable of causing severe pain with the bite.
Another one of the insects that are in the category of the smallest in the world is the common mosquito. It has dimensions from 3 to 7 millimetres. Despite its size, this animal is capable of transmitting several viruses, which cause different types of serious diseases.
The common mosquito is a cosmopolitan species, with wide distribution in America, Africa, Asia and Europe.
Another group of small insects are the fleas, which are grouped in the order of Siphonaptera, and of which about two thousand species are known. They are ectoparasitic and hematophagous animals that feed on a wide range of vertebrate animals, including humans.
Fleas measure between 1.5 to 3.3 mm in diameter. However, they are capable of long jumps that reach horizontally up to 10 times their size. Importantly, they are transmitters of various disease-causing pathogens.
These small insects correspond to the Boreidae family, which is not very diverse in this class, as it has approximately 30 species.
They are located in the northern regions, so it is considered a boreal species. The size of these insects does not exceed 6 millimetres, and their wings are vestigial or completely absent.
Western Pygmy Blue Butterfly
Compared to the rest of the insects described, its size is larger, but it seems important to consider one of the smallest butterflies in the world within the group. It is native to America, distributed from the United States to southern Venezuela.
It is a small copper-brown butterfly with blue at its upper base and has a wingspan of only 12 to 20 millimetres.
As we could see, this article was developed not only based on the species but also on some groups were incorporated. The great diversity of existing species can lead us to the elaboration of several articles. However, the main intention has been to serve different types of small insects.
