Insect specimens are an important part of biological research and natural history collections. Not only do they help scientists study insect taxonomy, ecology, and evolution, they also provide a valuable observation and learning resource for nature lovers and educators.
The process of making insect specimens includes three main steps: collection, processing and preservation. First, insects need to be collected in the natural environment, and common methods include the use of insect nets and traps. After collection, the insects are immobilized in a container containing formaldehyde to prevent spoilage.
The next step is the treatment of the specimen. Insects need to be dehydrated and dried to prevent mildew during long-term storage. Treatment methods commonly used include placing the insect in a hot stove, or soaking it in alcohol, and then fixing its wings and feet on cardboard to maintain its natural posture.
Finally, the insect specimens are placed in a special specimen box with detailed collection information, including the location, time and species of the insect. This information is essential for subsequent research and analysis.
Insect specimens not only play an irreplaceable role in scientific research, but also provide natural history enthusiasts with an opportunity to observe the microcosm of the natural world. By studying insect specimens, scientists are able to gain insight into insect diversity, ecological roles, and interrelationships with the environment.
