How to Preserve Insects for Collection
Insects have fascinated humans for centuries, and their intricate designs and behaviors have been a source of endless fascination. For those who are interested in entomology, collecting insects can be a rewarding hobby. However, preserving these delicate creatures for future study or personal enjoyment is essential. In this article, we will discuss the various methods of preserving insects for collection, ensuring that they remain in pristine condition for years to come.
The first step in preserving insects for collection is to catch them using appropriate tools. A net is the most common tool for catching insects, but it is important to use a fine-mesh net to avoid damaging the insects. Once caught, the insects should be placed in a container immediately to prevent them from drying out or being crushed.
One of the most popular methods of preserving insects is through the use of alcohol. This method involves placing the insects in a jar filled with a 70% to 90% ethanol solution. The alcohol preserves the insects by killing bacteria and fungi, which can cause decay. It also helps to prevent the insects from drying out and becoming brittle. To prepare the insects for alcohol preservation, they should be pinned with a fine needle or insect pin and then placed in the jar. It is important to ensure that the insects are fully submerged in the alcohol to prevent mold growth.
Another method of preserving insects is through the use of pins and pins strips. This method is particularly useful for larger insects, such as butterflies and beetles. To prepare the insects for pinning, they should be placed in a killing jar filled with a mixture of ethanol and a small amount of chloroform. After the insects have been killed, they should be pinned using a fine needle or insect pin. The pins should be arranged in a natural position, and the wings should be spread to prevent them from becoming brittle. The pinned insects can then be stored in a drawer or cabinet with a desiccant to absorb any excess moisture.
For smaller insects, such as ants and beetles, a technique called “drying” can be used. This method involves placing the insects in a dry, well-ventilated area for several days. The insects should be pinned as they dry to prevent them from becoming flattened or damaged. Once the insects are completely dry, they can be stored in a container with a desiccant to maintain their condition.
It is important to handle insects with care throughout the preservation process to avoid damaging them. When handling insects, use gloves to prevent oils from your skin from contacting the insects. Additionally, avoid touching the insects with your fingers, as oils and dirt can damage their delicate exoskeletons.
In conclusion, preserving insects for collection is an essential step for anyone interested in entomology. By using methods such as alcohol preservation, pinning, and drying, you can ensure that your insects remain in excellent condition for years to come. With proper care and attention, your insect collection can serve as a valuable resource for study and enjoyment.
