First, put the insects into the softening tank, and after several hours, take the softened insects out of the drying tray.
Second, then pat the appropriate wings and start the whole posture. Coleoptera, the whole posture of the foot is dominant, and the insect needle is inserted at the base of the right Coleoptera wing.
3. Insect needles for fixing insect specimens are made of stainless steel, from fine to thick, with seven grades: 00, 0, 1, 2, 3, 4 and 5. From No.0 to No.5, all the needles in six grades have caps. Only No.00 has no needle cap, only half the length of other needles, as a double needle insertion specimen. This time, fix the bug with 3# needle first. Before, a layer of A4 paper was nailed on the foam surface to solve the problem that plastic foam hooked the tarsal bone.
Fourthly, the foot has been adjusted, mainly aiming at the left-right symmetry and the coordination between the middle foot and the hind foot.
Five, after the completion of the insect needle, according to the most correct posture of insects, such as the position of wings, the bending degree of insect feet, the extension direction of tentacles, etc., to adjust the insect needle locally. One by one, let it have the same posture as a living insect.
Six, after the needle and posture, the next step can be to put the worm in a safe and ventilated place and go out to dry for a while. This stage generally takes 1~2 weeks, which can be completely dried.
7. Finally, add a proper amount of moth-proof and mildew-proof chemicals into the prepared insect specimens, and then insert labels. If the number of specimens is large, it is necessary to classify the specimens into specimen boxes and place them in dry and dark places.
