Tide bugs. Tide insects, dumpling insects, ground lice, ground lice, watermelon insects. Wait. Extend.

The body of the tide insect is oval or oblong, relatively flattened, with a slightly raised back, and the body can be curled into a spherical shape. Some species have a smooth back, while others have coarse grains. The head is small, inconspicuous, embedded in the anterior border of the 1st thoracic segment.

The cephalic segment has prominent lobes in the middle and on both sides. Broad chest, 7 free joints. The abdominal segments are 6 segments, the first two abdominal segments are narrower, but not significantly narrower than the chest, and each segment narrows posteriorly.

The flanks of each thoracic and abdominal segment are generally enlarged to form lateral lobes, the outer terminal angles of each thorax and abdomen on both sides protrude posteriorly and inferiorly, and the ends of the caudal segment protrude posteriorly and are triangular.

The eyes are well developed and compound eyes. The first antennae are small, with short whiskers at the apex; The second antennae are long, with 5 stalk segments and 2 whip segments. The labial base is arcuate, the large jaw has no tentacles, the cutting part is highly chitinized, generally has 2 toothed plates, there are membranous small lobes behind the tooth plates, and the molars are degenerated.

The outer lobe of the first small jaw is a masticatory leaf, and the inner lobe is narrow and long, with 2 stiff hairs; The second jaw is divided into 2 lobes at the apex, with an outer margin angular process near the base. The base of the jaw limb is broad and lamellae.

Tide insects are one of the groups of crustaceans adapted to life on land, usually living in moist, humus-rich places, such as under rocks in damp places, under decaying wood, in tree hollows, in damp grass and moss, under water tanks in courtyards, under flower pots, and even in damp places indoors. Omnivorous, eating dead leaves, dead grass, green plants, fungus spores, etc.

The scientific name of the skin bug is a tick (pí). Morphological characteristics of ticks: oval body, flat ventral dorsal and slightly raised dorsal surface when not sucking blood, adult body length 2 10 mm; After saturation, it swells like red beans or castor beans, and the largest ones can be up to 30mm long.

Leather on the surface, or with a chitinized shield on the back. The body of the worm is divided into two parts: the jaw and the body.

Leather on the surface, or with a chitinized shield on the back. The body of the worm is divided into two parts: the jaw and the body.

Ticks belong to the parasitic order Mites, the family Ticks. Adults have a strong chitinized shield on the back of the body, commonly known as Ixodes dyes, belonging to the Ixodes family; Those without shields, commonly known as soft ticks, belong to the family Soft Ticks. More than 800 species have been found in the world, including about 700 species of Ixodes family, about 150 species of Ixodes family, and 1 species of Natosidae family (only existing in Europe).

Ticks have a tendency to change hosts throughout their life cycle. It can be divided into four types according to the number of times it changes hosts:

1. Single-host ticks: each stage of development is on a host, and the female is saturated and lays eggs on the ground. Such as tiny cowticks.

2. Two-host ticks: The larvae develop as nymphs on one host, and adults parasitize on another host. Such as the remnant glass-eyed tick.

3. Three-host ticks: larvae, nymphs, and adults parasitize on three hosts. Such as Ixodes all-groove and Ixopodes prairie ticks. More than 90% of Ixodes ticks are three-host ticks, and most of the important vectors of tick-borne diseases are three-host ticks.

4. Multi-host ticks: larvae, nymphs and adults of all instars, and female ticks need to find a host to parasitize and suck blood before each oviposition, and leave after each full blood. About the size of a mung bean before blood sucking; After sucking blood, it can reach the size of a thumb. Usually soft ticks are multihost ticks.

There are no skin worms, only "ticks".

Ticks, also known as ticks, ticks, and grass crawlers, are extremely small arthropod parasites of the subclass Ticks subclass Tick Family, which means that although the name is "worm", it is actually closer to spiders.

Ticks are roughly divided into two categories: hard ticks and soft ticks, and the hard ticks family has a hard shield on its back; Soft ticks do not have a shield on their backs. There are more than 800 species of ticks known in the world, and more than 100 species are known in China, including 100 species of Ixodes and 10 species of Soft Ticks. Ticks have four forms: eggs, larvae, nymphs, and adults, and all other forms survive by sucking blood except for eggs.

They also have a wide range of blood-sucking ranges: mammals, including cats, dogs, people, birds, and reptiles, can be sucked by it.

Several forms of deer ticks or black-footed ticks).

Ticks are not agile insects, they cannot fly or jump, and can only slowly crawl to the blood-sucking site by attaching themselves to their prey. But because of this, tick-infested organisms often don't immediately notice the presence of ticks. Whenever the temperature rises, it means that the tick active season has arrived, and in our country, from April to October is the active time for ticks.

Once bitten, go to the hospital as soon as possible**, and never remove it at home. The dermatitis caused by tick bite is mainly anti-inflammatory, anti-itching, and analgesic, and symptomatic treatment is given at the same time. The following measures are often taken after a tick bite is found:

1. Do not forcibly remove the tick bite when it is found, so as not to tear it and prevent the mouthparts from breaking in the skin. You can apply ether, chloroform, and dry tobacco oil to the head of the tick or light a cigarette butt next to the tick, and roast it with mosquito coils, and the tick will loosen itself after a few minutes, or apply petroleum jelly or liquid paraffin to the head of the tick to suffocate it, and then gently pull the tick out with tweezers.

2. After removing the tick, the wound should be disinfected, and if the mouthparts of the tick are found to be broken in the skin, it should be surgically cut and removed.

3. Use 2% lidocaine hydrochloride around the wound for local sealing, and some people use trypsin 2 000 u and 100ml of normal saline to wet the wound, which can accelerate the healing of the wound.

4. Antihistamines such as chlorpheniramine, desloratadine, levoxetirizine hydrochloride or corticosteroids such as melasone, prednisone, etc. should be given in case of systemic poisoning. Tick paralysis or tick bite fever should be rescued in time. If there is a secondary infection of the wound, anti-inflammatory** should be performed.

After this insect bites a person or animal, the head will be inserted into the ** blood sucking, and the stomach will become very large. Otherwise, life would be in danger.
