How to make a butterfly specimen if the props are often touched in life ?

Our eleventh homework was to make insect specimens, but I didn't catch a butterfly, I made a locust, the first one was very detailed, and the teacher almost said the same, so it should be no problem to do it.

<> make butterfly specimens is divided into 3 steps, and the tools to be prepared are wing-spreading plates, wing-spreading paper tapes, insect needles, pins, and tweezers.

Here are the detailed steps to make a butterfly specimen:

Steps.

Separate the butterfly wings.

Pinch the butterfly's chest, use tweezers to separate the wings, and pierce the insect needle vertically from the butterfly's back into the chest.

Pin fixation of butterflies.

Then the insect needle is pierced vertically into the middle of the groove of the wing plate, and the wing-spreading paper tape is covered on the wing, which is fixed with a pin.

Dry the butterflies. <>

After 3-4 weeks.

Wait until the butterfly is completely dry, and remove the specimen from the winged board.

The method of making butterfly specimens is as follows:

1.Pour the hot water of about 80 degrees Celsius into the bowl-shaped container, making sure that the bowl mouth is large enough. Then gently grip the front chest of the butterfly with tweezers and immerse the butterfly's torso in hot water so that the water is submerged over the base of the wings.

Then when the roots of the butterfly's wings are soft, take out the butterfly, absorb the water with a paper towel, and put it on a foam board (the middle ditch is used to place the torso in advance) and start to tidy up the shape.

Pierce the butterfly's chest with a pin, secure it to the foam board, and slowly lay the wings flat and stretch to the ideal shape, taking care to be gentle or it will break.

2.Use two plastic splints to flatten the butterfly wings in a posed position, fix them along the edge of the wings with a pin, and never move the splints, otherwise the shape will be destroyed and asymmetrical, and the wings will be torn apart.

3.After the butterfly is fixed, it is placed in a ventilated position, and in about three to four days, the pin can be removed, heated with hot melt glue and smeared in the specimen box, the butterfly torso is pressed against the glue for one minute, and the posture is adjusted, and the lid can be sealed, so that the butterfly specimen is completed.

If you don't have a butterfly trap, a triangular bag, a triangular box, a poison bottle, and a collection kit, then I'll teach you a simple way to do it, which I invented myself

Using two pieces of styrofoam, dig a narrow groove on each of them, the size is suitable for the trunk of your butterfly, put the butterfly on one of them, stretch its wings, align the other piece and press it up, press a weight on it, and let it sit for about a day and a night.

Then open it and dry it with a hair dryer, it will be very brittle after drying, be especially careful!

I believe you have prepared the box and the base (there are no requirements for the base, as long as it can be stored for a long time, such as wood or styrofoam), and you can fix the butterfly on it, with glue or nails.

Finally, mothballs and desiccant should be put in the box, and the box should be sealed, and latex can be considered if it cannot be sealed with wax.

If you catch a butterfly and find that its wings and other parts are damaged, you should release it. Such a butterfly no longer makes sense for taxidermy and collection, and releasing it into nature will make its life more meaningful.

After catching a suitable butterfly with an insect net, when the butterfly's wings are closed, use your fingers to squeeze the flying muscles at the base of the butterfly's wings outside the net, so that it quickly suffocates and loses the ability to fly. Then soak the butterfly's head in alcohol and put it in a triangular bag. Be careful not to touch the front of the wings and destroy the scale powder on them, so that we can make beautiful specimens.

Tools: scissors, rulers, foam, tweezers, sulfuric acid paper, pins, carving knives.

Step 1: Draw two parallel lines on the foam board with a carving knife according to the width of the butterfly's body, and control the depth to about 1cm.

Step 2: Use tweezers or other sharp objects to pick out the middle part of the parallel line, trying to keep the edge of the groove as flat as possible.

Step 3: Slowly open the closed butterfly wings with the tension of the tweezers, and insert the insect needle from the butterfly's chest and dorsal**, leaving a distance of about 5mm from the upper end.

Step 4: Cover one side of the butterfly wing with cut sulfuric acid paper, take tweezers to gently lift the butterfly's forewing, so that the trailing edge of the forewing is perpendicular to the butterfly's body, this step must be extra careful, try to flatten the butterfly wings while paying attention not to destroy the scale powder on the butterfly wings.

Step 5: Next, use a pin to fix the sulfuric acid paper to keep the butterfly wings in a flat posture, you need to pay attention to inserting the needle as close to the contour of the butterfly wing as possible, and the needle should be staggered and obliquely inserted to increase firmness.

Step 6: After a few days, wait for the butterfly's body to dry and its wings are steadily flattened. Remove the butterfly specimen from the sulphuric acid paper and you're done.

Butterfly specimens are not only beautiful, but also easy to understand the morphological structure of butterflies. The process of collecting and making butterfly specimens is also very particular, and it requires the use of appropriate tools and methods.

First of all, to collect butterfly specimens, use an insect trap net, hold the handle of the net tightly, face the insect head-on with the mouth of the net, and then use the net to head in the pocket. When the insects enter the net, the net should be twisted sharply so that the bottom of the net is stacked on top of the net opening, and the insect will not escape.

Secondly, after catching the insects, put them in a triangular paper bag, which will prevent the scales on the wings from falling off. Then put in a sterilized bottle to kill the butterfly.

Thirdly, to make a taxidermy of a painted butterfly, it is necessary to insert needles, spread wings, and preserve.

Needle insertion, take out the poisoned butterfly from the sterilization bottle, and insert it with an insect needle, and the needle insertion site has strict requirements: it should be inserted in the middle chest of the butterfly. The direction of the needle should be perpendicular to the body of the worm. Leave about one-fifth of the needle length at the upper end of the needle.

Spread your wings, fix the butterfly on the wing-spreading board, and spread the wings so that the left and right wings are symmetrical. Then a strip of paper is pressed against the two pairs of wings, and the ends of the strip are secured with needles. Then arrange the antennae and feet and place them in a ventilated place to prevent direct sunlight. Remove the worms when they are completely dry.

To preserve, put the made insect specimens in the insect box. When inserting, it needs to be arranged neatly and evenly. Labels should be placed on the bottom of the specimens indicating the location, time and name of the person collecting the specimen. Camphor must be placed in the box to prevent insects.

As long as you master the process of making butterfly specimens, you can also make beautiful butterfly specimens.
