If the sample has dried, first soften the sample and spread clean wet sand on the bottom of the covered plastic box or iron box. It is best to add a small amount of carbolic acid to prevent mildew, put an iron partition on the frame, spread two layers of gauze, and then dry the specimen. Finally, the container is sealed for a few days, and the dried specimen can be softened. At this time, you can spread your wings and use a piece of hard foam plastic as a display board with a groove in the middle, which is wide enough to accommodate the chest and abdomen of the butterfly. When making a specimen, insert the specimen needle or long needle into the middle of the butterfly's chest, and then lay the butterfly flat in the groove between the grooves. Then press the left wing on the wingspan board with a narrow paper strip, move the wing base with tweezers, adjust the position of the wings so that the rear edge of the butterfly's front wing is perpendicular to the body, then spread all the rear wings, and flatten all the wings with smooth paper strips and pins. Spread your right wing in the same way and adjust the posture of your tentacles and abdomen so that you can spread your wings. Then, put it in the shade for about a week, open the paper, hold the long needle and take out the butterfly, and the specimen is ready. But don't forget to make a label.
Each specimen should be accompanied by the collection place, time and collector. It is best to label the family, genus and species of butterflies and put them into the specimen box in different categories. The specimen box should be tightly sealed, and mildew-proof and insect-proof drugs should be put in the box, which should be placed in a dry and cool place to prevent mildew and insects.
