How to make plants, insect specimens, how to make insect specimens?

Here's how to make an insect specimen:

There are two main types of insect specimen production methods: needle insertion and liquid immersion. Generally, the needle insertion method is used to make specimens.

If you need to make an insect ecological box, you can also arrange the insect specimens and dried plants, flowers and plants in the same glass cover, or in other art frames.

The insect needles used to fix insect specimens are made of stainless steel, from fine to coarse, and there are 7 levels, including No. 00, No. 0, No. 1, No. 2, No. 3, No. 4, and No. 5. From gauge 1 to gauge, all 5 levels of needles come with needle caps. No. 00 and No. 0 are not equipped with needle caps, and their length is only half the length of the other needles, and they are used as double needle insertion specimens.

For insects that have not dried and hardened or are still soft after death, they are fixed with the needles mentioned above. The size of the needle to use should be determined according to the size of the worm. At the beginning of the needle, the insect body to be made is placed on the stinging insect table or the table seam, and then according to the size of the insect, the appropriate needle is selected, the insect needle is inserted into the middle line of the dorsal midline of the base of the forewing, the hemipteran insect is inserted in the front thorax ** or the small shield midline is on the right, and other insects are inserted in the middle thorax**.

After the needle is inserted, the insect after needle insertion must also be adjusted locally according to the most correct posture of the insect, such as the position of the wings, the curvature of the insect feet, the elongation direction of the antennae, etc., so that it has the same posture as the live insect. Some insect enthusiasts like to fix insects in the posture they like, and can adjust the posture and position of the insect's body, wings, legs or antennae according to their own requirements.

1. Put the insects in the soft tank, and after a few hours, take the soft insects out of the drying dish.

2. Then take a suitable winged plate and start the posture, and the coleoptera insects are mainly based on the posture of the feet, and the insect needle is inserted at the base of the right elytra.

3. Adjust the foot, mainly the symmetry of the left and right and the coordination of the middle foot and hindfoot.

4. After the completion of the needle insertion, according to the most correct posture of the insect, the insect after the needle insertion is partially adjusted, such as the position of the wings, the curvature of the insect feet, the elongation direction of the antennae, etc., so that it has the same posture as the live insect.

5. After inserting the needle and reshaping the posture, the next step is to place the insect in a safe and ventilated place to dry for a period of time, and this stage generally takes 1-2 weeks to completely dry.

6. Finally, add an appropriate amount of anti-moth and anti-mildew agents to the insect specimens, and then insert a label. If the number of specimens is large, it is necessary to put the specimens in a specimen box and store them in a dry place away from light.

The process of making insect spikes is as follows:

1. The specimen is soft.

Mainly infiltrate the insect body with water vapor to make it soft, in the laboratory is used in a glass drying dish, add water to the bottom of the dish, put the specimen in the triangular bag or cotton bag on the partition, put it for three or five days, touch the antennae to determine whether it can be freely fiddling. If the time is short, it will not be soft enough, and the medium that is easy to become fungal bacteria will be discarded if the time is long.

2. Insect needles fix the chest.

Insect needles are selected according to the size of the insect. The fin plate can be made of various materials, as long as the needle is firmly pierced and the knife can be chiseled, the most convenient and easy to obtain is the plastic foam board.

3. The head pin assists in fixing the body.

Hold the left and right sides of your abdomen in place with pins, taking care to keep your abdomen centered.

4. Spread your wings. Paper or film is used to press the fin surface, and the corners and edges of the paper are fixed with pins. Choosing paper or film is not expensive according to personal preference, and sulfuric acid paper is better in terms of environmental protection.

5. Placement of feet and antennae.

The usage of pins here can be described as ever-changing, one needle can be pressed and separated, two needles can be framed and clamped, and two can not be fixed on three or four.

6. Air drying and needle withdrawal.

After the posture is completed, it can be air-dried for three or five days, and it is difficult to withdraw the needle. After air-drying, the specimen is very fragile and should be cautious when removing the needle, and remove the pin in the order of antennae, wings, and abdomen, and remove the specimen.

7. Label and save.

In addition to the insect body itself, an insect specimen with complete information also needs to be named and labeled, which are arranged below the insect specimen.
