1, soften the dead butterfly:

It is of course good for butterflies to pin, spread their wings and shape after death. But it is easy to dry and harden, and appendages and wings are easy to get hurt and fall off, which is inconvenient for plastic surgery and needs to be softened. The method of softening is: put the butterfly in a box full of wet sand, then cover it, and it will soften in about 2 ~ 3 days. In order to prevent butterflies from becoming moldy due to high humidity, drop a few drops of carbolic acid or formaldehyde solution into the sandbox.

2. Pin:

Take out the softened butterfly with tweezers and carefully spread your wings. Insert a sewing needle from the middle of the worm's chest and back and pass between the feet.

3. The posture of spreading wings:

Spread your wings and straighten the wet butterflies on the display board. The wing display board can be made of cork or foamed plastic, with a thickness of 1.5 ~ 1.3 cm, a width of 8 cm, a length of 15 ~ 25 cm, and a groove with a depth of 1 cm and a width of 1.5 cm should be opened in the middle, which can be used at one time. When operating, insert the butterfly with the needle into the cork board along the groove of the planking, so that the butterfly's body is just placed in the groove. The base of the wing should be parallel to the plane of the exhibition board, and the wing should be spread to the left and right with tweezers, so that the front wing and rear wing are at right angles to the insect body.

Then press two pieces of paper on two pairs of wings. The two ends of each piece of paper are fixed with needles, and the belly of the butterfly in the groove should be supported with paper to prevent sagging. In a word, we should try our best to keep the natural beauty of butterflies in the process of spreading our wings and adjusting our posture. ?

Introduction:

Butterflies, commonly known as "butterflies", have about 14000 species all over the world, most of which are distributed in America, especially in the Amazon River basin, and are distributed in other parts of the world except the cold regions of the North and South poles. Taiwan Province Province in Asia is also famous for its wide variety of butterflies. Butterflies are usually brightly colored, with various spots on their wings and bodies, and a pair of rod-shaped or hammer-shaped antennae on their heads (this is the main difference from moths, which have diverse antennae).

The largest butterfly can spread its wings up to 24 cm, and the smallest is only 1.6 cm. Big butterflies attract people's attention, and some people collect all kinds of butterfly specimens. In the United States, "butterfly watching" migration, like "bird watching", has become a new activity, attracting many people to participate. There are many kinds of butterflies that are the main pests of agriculture and fruit trees.
