The brightest representative of arachnids — micromat greenish greenish got its name because of its bright protective green color. This color is promoted by a special substance bilan micromatabilin, which is found in tissue fluids and hemolymph of the arachnid. This is the only representative of the Sparassidae family that can be found in our country. And unlike other representatives of this genus, they are safe for humans.
Origin of the species and description
The arachnid class originated around 400 million years ago. Of all the organisms that live on our planet, arachnids are the most ancient. Spiders easily adapt to changing environmental conditions, change easily. They multiply quickly and live for quite a long time.
The main distinguishing feature of arachnids is the web that they are able to weave. Some spiders use the web as a trap, while others use it to move and save food. And also many spiders lay eggs on the web in order to save their offspring.

Micrommata virescens or green micromat belongs to the genus Micrommata of the Sparassidae family, this family includes 1090 species of arachnids, which are grouped into 83 genera. This species is commonly called the Huntsman spider, which translates as «Hunter». All representatives of this family are swift and agile predators.
They prey on their prey without the help of a web, attacking the prey and biting it. The micromata belongs to the group of crab spiders. These spiders got this name due to the special structure of the limbs, and a strange gait more like the movement of a crab. The spider moves as if sideways.
For the first time, this species was described by the naturalist from Sweden Karl Klerk back in 1957. He gave this species the name Micrommata virescens. Also, a detailed article was published about this species in the publication Kosmos-Atlas Spinnentiere Europas by the famous zoologist and writer Heiko Bellman.
Appearance and features
Micrommata virescens are small spiders about 10 mm in size, the females of these spiders are slightly larger, about 12-15 mm in length. These spiders have an intense bright green coloration, which helps them hide well during the hunt and be completely invisible.
The body of a spider consists of a cephalothorax and 8 powerful limbs. There are 8 eyes on the head of the spider, which provides a fairly wide view. On the abdomen of males, a red stripe is noted, several yellow stripes adjoin it. On the sides of the males, you can also see several stripes of bright red.
Young spiders also have an intense green color, but closer to the onset of cold weather, the color of the spiders changes to yellow-brown, with reddish dots. The micromata is the main relative of the tomosids, and is very similar to them in its structure of the limbs. Although to hunt them.
The limbs of this species of spiders are of different sizes. The spider has two pairs of forelimbs that are much longer than the hind pairs. Because of this, spiders have a very peculiar gait.
Although spiders look very neat and graceful on the outside, they are very fast. Spiders jump high, they can move incredibly quickly on the grass. Even having stumbled, the spider can hang on its web, and then jump to the nearest leaf.
Now you know if greenish micromat is poisonous or not. Let’s see where this spider lives.
Where does the greenish micromata live?
The habitat of the greenish micromat is quite extensive. Greenish micromat can be found in the warm forests of China, in the Caucasus, in the southern part of Siberia, as well as in the Far East, in Yakutia and in the central strip of our country.
These green spiders settle in thickets of grass. They can be found in sunny clearings and forest edges. On the slopes of mountains in fields, bushes and vineyards. Also, a greenish micromat can be found in any park on the lawn and in bushes. These spiders, unlike many of their relatives, love bright, sunlight, they may well exist in glades well-drenched in the sun.
These arthropods are thermophilic. For humans, Micrommata virescens is absolutely safe, unlike other members of the banana spider family, so you should not be afraid of seeing such a spider proudly sitting on a plant.
For life and hunting, the spider chooses narrow green leaves, they live on ears of corn. The spider moves quickly, and easily changes its place of residence. If the spider is very frightened, it can quickly move to another place and find shelter there. Spiders are well camouflaged in the grass, so they are difficult to see. In fact, there are a huge number of them on any lawn.
What does the greenish micromata eat?
Basic diet micromata are various insects:
- flies of various species;
- tomizode spiders;
- tenetika spiders;
- cockroaches and other small insects.
Interesting fact: Green micromata can hunt insects several times larger than itself, and this does not frighten it at all.
The hunting process of the green micromat is very interesting. In order to be unnoticed, the spider finds a thin green leaf. A spider sits on a leaf hanging its head down. He puts his front paws in front of him, and with his hind legs he rests tightly on the surface of the sheet. Before hunting, the spider fixes its web thread on the plant in advance, and when an insect appears in the spider’s field of vision, the micromat is repelled with force by all its legs and gently rolls down the leaf. Having crushed the unfortunate insect under itself, the spider bites it a couple of times and drags it to a convenient place. In order to feast on the unfortunate insect later.
Interesting fact: If during the hunt, the spider’s prey tries to escape, the spider jumps off the leaf, hanging along with the victim on a safety thread. In this case, the victim of the spider can no longer resist, and she can only die.
The strength of the spider is that when hunting, seeing the victim, he can quietly land right on it. In this case, the insect does not have time to react quickly, the spider bites it and takes it to a secluded place where it can feast on prey.
Peculiarities of character and lifestyle
Micrommata virescens hunt during the day and evening. They patiently wait for their prey in the bushes, and on the grass they merge with them due to their coloring. Spiders of this species can most often be found in late May and June. The breeding season comes in August. The life of the micromat passes calmly, after the hunt, having had enough, they calmly bask in the sun.
Spiders are very dynamic in nature. They move very fast. This type of spider is undemanding to nutrition, and due to the unusual color and undemanding conditions of detention, they are often grown at home. Micromat spiders live alone. They are cannibals and can eat their own kind. Especially small spiders like to have a bite to eat with young tomizodes and tenetik spiders. After eating relatives, they have an appetite, and they feel good.
Spiders of this species weave a cocoon web only during the breeding season in order to lay eggs there. One female takes care of the offspring. Family ties and social structures are not traced. The spider meets the female only during the mating period, after the completion of the fertilization process, the spider is removed forever. hatching spiders quickly find food in the form of other spiders.
Social structure and reproduction
As mentioned earlier, the greenish micromat leads a solitary lifestyle. Male and female meet once exclusively for mating. At the same time, the male attacks the female and painfully bites her with chelicerae. Up to the point that drops of blood appear on the belly of the female. The female always tries to run away, but the male watches and hunts her. The male strongly digs into the female’s abdomen, and waits until she calms down, then mates with her.
The mating process occurs as follows: the male climbs onto the female, bends down and introduces his cibilium into the female. Mating lasts several hours. Although the introduction of cibilium is carried out only once. Some time after mating, the female spider begins to weave a cocoon in which she will lay her eggs.
A cocoon that turns out to be quite large, it usually hangs in the air above the ground. The female micromat zealously guards the cocoon with eggs until the little spiders wriggle out of it. After that, the female leaves her offspring. Her brood no longer needs her help. Spiders do not form special family ties. Young spiders get their own food by attacking other spiders.
Natural enemies of greenish micromat
Natural This type of arthropod has a lot of enemies, but due to the fact that they are very good at camouflage, nothing threatens their numbers.
The main enemies are:
- gryllotalpa unispina (bear);
- wasps and bees;
- other spiders.
The main enemy of the micromat is the bear gryllotalpa unispina. She attacks weakened spiders and eats them. Medvedka is much larger than this type of spiders and loves to eat them very much. Also, centipedes, geckos and hedgehogs are considered natural enemies of this species. Most often, it is inexperienced and young spiders that die. Often they simply cannot cope with their prey during the hunt and die themselves. Or they cannot distinguish a predator and approach it imprudently close, although, having learned about the danger, spiders can hide very quickly.
Wasps and bees of various species are considered no less dangerous enemies of spiders. Wasps do not eat the spider, they use its body to keep their offspring. Wasps paralyze spiders, take them to their lair and lay eggs in the spider’s belly. The hatched wasp larvae eat the spider from the inside.
As mentioned earlier, Micrommata virescens are cannibals. They can attack their relatives and kill them. The main threat comes mainly from large spiders. During mating, females often die from injuries. There is no reason for the spider to kill her, however, the female may die from mistreatment of her.
Population and species status
Despite the fact that we rarely notice spiders of this species, in principle, nothing threatens the population. The greenish micromat can be well camouflaged and therefore it is not visible on the green landscape. This species successfully inhabits the fields and forests of our country. It spreads quickly and is capable of moving, although it prefers warm and bright places. When breeding, the female lays a large number of eggs in one litter, and many new spiders hatch from them.
Of course, human activity has a bad effect on the population of this arthropod species. And in general, all kinds of living beings on our planet.
Man cuts down forests, fields and parks become smaller. The living creatures inhabiting green spaces die in large numbers, but this species is not threatened with extinction. This type of spider is too tenacious. Perhaps soon Micrommata virescens will be able to adapt to different environmental conditions and expand their habitat.
View «Micromata greenish» does not stand on the verge of extinction, and does not need special protection. But in order to preserve not only the population of this species, but nature as a whole, you need to take care that forests are not cut down and as many different green spaces as possible are preserved, pure natural corners untouched by civilization.
Micrommata virescens spider is safe for a person and does not attack people. A greenish micromat can only bite when defending itself, while the bite of a micromat does not pose a particular danger to humans. These little neon green spiders are not to be feared, they are not dangerous. Micromats can be grown in home terrariums, they are unpretentious. It is very interesting to observe the life of this type of spider. However, these insects are very fast and agile, and leaving even a small crack in the lid, the spider will certainly get out of the terrarium, and it will be difficult to find it.
