1. Use medical alcohol and put it in a glass jar. Medical alcohol can preserve insect specimens from decay, loss of moisture, or damage. The container jar should be larger than the insect, but it doesn't need to be particularly large. If you put a small insect in a large jar, you will waste a lot of medical alcohol. About 70% purity can be used to preserve insect specimens. Of course, higher purity alcohol is also possible. Higher purity alcohol will be better for storing specimens. Some insect specimens need to be stored in high-purity alcohol, such as spiders. , scorpions, earthworms. Make sure the glass jar has a very tight lid and doesn't have any gaps.

2. Find a dead insect. Remember that soft-bodied insects are preserved in alcohol. Insects can be obtained from many places, including your home's windows, the surrounding environment, or nearby spider webs. You will want to preserve the insect specimen as it appeared in life. If the insect has been dead for a few days, has begun to decay or become damaged, there is no point in preserving it. You can also prepare insects yourself, there are many ways, such as catching butterflies using a butterfly net. The method of designing traps is effective.

3. Identify and label your insects. When preserving insects, it is important to know the species. This is also a very important process for preserving insect specimens for scientific research purposes. The label should include the species, date and origin of the insect and include the name of the discoverer. Glue the label to the outside of the glass jar. There are many websites that provide information about insects to help you learn about them.

4. Put the insect specimens into the glass jar with care. Insect specimens are fragile and easily damaged. Your best bet is to use tweezers to avoid damaging the insect specimen with your fingers. If the insect has a sting or other poisonous parts, wear gloves when handling it.

5. Now fill the remaining space with alcohol. This work is only done once after placing the insects into the glass jar. Pour in the alcohol slowly. If you pour it too quickly, the liquid may damage the insect specimen. Close the lid and store it in a safe place. If you're planning to start a large insect collection, it's a good idea to devote the entire tabletop to the jars. Store insect jars away from food, children and animals.

6. Fill two-thirds of the glass jar with hand sanitizer. Like alcohol, hand sanitizer can store insect specimens and preserve them from spoilage. However, unlike alcohol, the concentration of hand sanitizer will cause the insect specimen to hover, making it easier for humans to observe. Use glass jars that are large enough to contain suspended insects, but don't waste too much hand sanitizer.

7. Put the insect specimens into hand sanitizer and avoid operating them directly with your hands. It is recommended to use tweezers. Gently place the insect specimen into the jar until it is suspended in the hand soap. If you are placing a specimen of an insect, such as a bee, be careful not to damage its wings when you place it in the jar. Larger insect specimens, like butterflies, may not fit easily into the jar, and hand sanitizer may stick to parts of the insect's body making it difficult to handle. When saving, prevent it from extending its wings or antennae.

8. Boil the jar in hot water before use, add hand sanitizer and remove bubbles. Put 5 cm of water in the pot, bring to a boil, put the jar into the water and cook for 15 minutes. Remember to open the lid to avoid explosion. Avoid getting water into the jar, which can dissolve the hand sanitizer.

9. Fill the jar with hand sanitizer. Once you remove the jar from the water and allow it to cool to room temperature, pour in the hand soap until the insect specimen is suspended and fill the jar. Once the jar is full, you can use tweezers to adjust the position of the insect until it's in the position you like. Stick the label on the outside of the jar, close the lid, and the preservation work is complete.

10. 1. Buy pins and bubbles. Insect pins are specialized thumbtacks made from special steel and are approximately 3cm long. Be very fine to avoid damaging the specimen. Any type of foam should be used to mount the insect, with a density suitable for push pin mounting. Have thumbtacks and foam ready in advance.

11. Pin insect specimens to thumbtacks, which is very effective in preserving hard insect specimens, including beetles and cockroaches. Thumbtacks driven through the insect's thorax. If you're anchoring a beetle, make the right wing through its middle.

12. Make a label. Find out the type of insect and print out a label. Pay attention to the place of origin and date, the person who found it, and some will also include information about the environment where it was found, such as on the leaves of a plant or under a log.

13. Fix the insects and labels on the foam. Simply drive the thumbtack into the foam until it's firmly in place. Be careful not to damage the insect specimen during this process. Then, use tape or thumbtacks to secure the tag under the insect.
