Insert the needle into the soft specimen, gently press the four wings with tweezers, select an insect needle with appropriate size, vertically insert it into the middle of the middle chest and back, and pierce the ventral surface, leaving smm on the chest and back at the tail of the insect needle. If you can't grasp the length correctly, you can measure it with a three-layer board. Because the height of each level of the three-layer board is 8 mm

2. Spread your wings and straighten your posture. First of all, arrange your hexapod so that it clings to the ventral surface of your body, and don't stretch or break it. Secondly, make your tentacles forward and your abdomen straight back. Then, insert the insect needle with butterfly into the groove of your wingspan, so that your butterfly body is just in the groove, and the insertion depth is so that the joint between the root of your butterfly wing and the body is just on the same level as the board. Then each hand pulls a pair of front wings forward with 1 fine worm needle at the same time, so that the rear edges of the two front wings are connected into a straight line and at right angles to the longitudinal axis of the body (it is best to pull the fine worm needle in the middle of the trimming front edge, behind the first pulse, because the first pulse of the front wings is the thickest, so as not to tear the butterfly wings). Temporarily insert these two needles into the wingspan and fix them. Then take two other fine insect needles and pull the rear wing forward at the same time, so that the front edge of the rear wing is covered by the rear edge of the front wing. At this time, the exposed surface of the hind wing is the widest, which is also in line with the natural posture of the butterfly when flying. These two fine needles are inserted into the wing plate for temporary fixation.

Cut the thin and smooth paper into several narrow strips with a certain width with scissors, put it on the butterfly wings, trip the paper tightly, nail the two ends with pins, straighten the antenna and abdomen, or insert pins on the side plates of those parts to keep the butterfly in the most beautiful state, and then carefully pull out the fine insect needles on the four wings (only 1 insect needle on the chest), and the holes in the original wings will be

Do not insert the needle into the insect's body or wings, otherwise it will leave a hole.

The original triangular paper wrapped with butterflies usually has the words such as collection place and date. Please pay attention to cut it out and insert it beside it. Don't make mistakes.
