Prepare the tool materials: about 3 insect pins, 1 bottom plate of suitable size, 2 small KT plates and transparent plastic sheets.
?
fix the body. Place the specimen in the center of KT board, and fix the part between thorax and abdomen with two insect needles, which is usually a relatively small connecting structure. ?
?
watch the pin position at close range. ?
?
fix the foot. At the joint of femur (also called leg joint) and tibia of hind foot, two insect needles are used to fix it alternately and stick to the bottom plate. In this way, the whole hind foot is basically fixed, and the posture is slightly adjusted. ?
?
watch the pin position at close range. ?
?
fix the head. Use two needles to fix the head alternately, pay attention to observe from multiple angles and adjust the best position. ?
?
a pad for spreading wings. Careful observation shows that an included angle is formed between the forefoot and midfoot on the same side, and the included angle is relatively large, close to more than 9 degrees. This position is an important position for placing small pads for spreading wings, as shown in Figure ①.
insert a prepared small KT plate pad with the same height as the wing into this included angle position, and fix the pad with a needle, as shown in Figure ②. ?
?
spread your wings. The front and rear wings (or inner wings) of insects have interlocking structures to connect them when necessary. Therefore, as long as the method is correct, it is easy to pull the front wing and pull the rear wing together, and it is very beautiful when unfolded. ?
Pull the wing to a proper forward position to form a more dynamic angle, put a transparent plastic sheet on it and fix it with a needle. The wings can be easily fixed and flattened. ?

Extended information:
■ Disinfection of specimens.
Hymenoptera insects in the wild are often parasitized with a large number of mite, so it is best to soak them in alcohol for a period of time to kill them.
■ specimen cleaning.
After the mites are killed, they should be cleaned up to make the specimens look neater.
the cleaned specimen is drained with paper for later use.
