1. Pin insertion fixation
Generally, fresh specimens after poison killing are collected. If the specimens are dry and hard, they should be placed in a softener for 1-2 days before the needle is inserted to fix the worms; Carefully take out the insects from the softener with tweezers and put them on the whole posture stage, avoiding touching with hands as far as possible; Select the corresponding insect needle according to the size of the insect body, insert the insect needle from the slightly right of the midline of the back of the insect body, and pass it out from the abdomen, generally making the needle in the middle of the two feet.
2. Spread one's wings and straighten one's posture
Butterflies, dragonflies and other insects need to spread their wings. When spreading wings, first insert the specimen with the needle into the spreading plate carefully, so that the insect body falls into the groove, and the wings and the spreading plate are in a horizontal position. Then unfold the wings with forceps to make the trailing edge of the front wings perpendicular to the body. After the wings are adjusted to the ideal position, press the wings with the strip paper in one hand, and insert the pin around the strip paper in the other hand, but not into the wings, so that the strip paper and the wing extension plate can be closely combined to fix the wings. After spreading your wings, adjust the position of your antennae, feet and abdomen, and you'll be done.
3. Drying and storage
After the specimen completes the above actions, it is almost finished. The rest is to dry the specimen. Generally, it can be dried in a constant temperature box at 50 ° C for about a week. If there is no drying box, it can also be placed in an indoor ventilated place for drying.After drying, the specimen can be stored in the specimen box. The specimen box shall be stored in a ventilated and dry place.
Each specimen represents a life, which should be cherished and utilized. For example, carefully observe its shape, and try to classify and conduct other scientific research.
