Answer to the first question: Use an insect needle to straighten the legs, and then use 502 glue to tap on the joints. The glue dries quickly and the position of the hind legs is fixed. Reshape the antennae and legs one by one. If you are not satisfied, use chloroform to wash off the glue and try again;

Answer to the second question: It is not recommended to coat large animal specimens with formaldehyde and sprinkle some salt. If stored in the air, because this method cannot affect the body, microorganisms in the body will still move and eventually damage the specimen. Moreover, salt will absorb moisture and return to moisture on rainy days. Dried insects can be stored in the ambient air, but are easily damaged by other small animals (such as mice and borers). Some specimens cannot be cleaned after being stained with dust, which will affect the appearance, so it is recommended to keep them sealed and protected from light.
