After a few days in the collection, mantises and leafhoppers start to turn black. How can I avoid this ?

In acetone, it is necessary to soak-so that the fat is taken away. They'll lose their color anyway... You can touch it up later.

Females should be dissected, males should be dried quickly. But like acetone, it ruins your DNA. If the color is lost quickly, then the air is too humid where you are drying.

It's not necessarily the air. Darkening is the result of putrefaction, and its degree reflects the peculiarities of the putrefactive microbiome, which depend on many factors: air temperature, the state of the fat body, the contents of the intestine, etc. Under equal external conditions, hungry, emaciated individuals dry out best.

The soaking method is working. Not necessarily acetone, alcohol is also suitable. But the color will still be unnatural, although not dark. Preserving the natural shade of green is a rare piece of luck. Sometimes it happens, but you can't repeat it on purpose.

I have a friend who paints-you can't tell the difference from the living ones!

It turns out, of course, not a scientific copy...
