1. Insect needle: it is an essential tool for making butterfly specimens, generally made of stainless steel. Because butterflies are very different, the thickness of insect needles used is also different. Insect needles are generally 40mm long and vary in thickness, with the thinnest being No.0, the rest being 1 to No.4, and the thickest being No.5. ..

2. Pin: mainly used to fix butterfly wings.

3. Wing plate: it is a tool for arranging butterfly specimens. Mainly made of foam board, choose a long strip foam board according to the size of butterfly, and dig a small chute in the middle.

4. Tweezers: used to pull butterfly wings and reduce the damage of butterfly scales.

5, transparent layering paper: fix the butterfly wings flat.

6. Labeling: In order to ensure that the collected butterflies have academic value, the butterfly specimens made must be labeled. The label needs to record the time and place of collection, the name of the collector and the scientific name.

1. First, prepare the prepared wing display board, insect needle and pin. Take out the softened butterfly specimen, insert a suitable insect needle vertically into the middle chest of the butterfly, then insert it into the groove, so that the wing shoulder angle is parallel to the exhibition board, fix the insect body, then spread the wings, and clamp the front wing with tweezers to move forward, so that the rear edge line of the front wing is perpendicular to the middle chest, and the two rear edges are in a straight line. The front wing presses the rear wing, and the rear wing unfolds into a flying shape, and then it is pressed with transparent laminated paper and fixed with a pin. After the two sides are finished, the butterfly's head is reshaped, and the shape of the antenna is like a number 8. After the exhibition, the specimens were dried in a ventilated place and then moved into a specimen box for preservation.

Matters needing attention in the process:

1. Because there are many scales on butterflies, and some butterflies are small, and their wings are easy to rot, we must be careful in manual operation, and gently spread our wings with tweezers to prevent scales from falling off and maintain their characteristics and integrity, so as to facilitate the subsequent seed identification work.

2. Be sure to take off the display board after drying, otherwise the posture will not be fixed.

Don't stick the needle in your wing.
