Yeah, quite a budensis...

An injection of ammonia helps well in green butterflies. Before that, of course, you need to put the material in a humid environment for an hour and a half, so that the antennas soften.

Tell me, does anyone know an effective way to save (at least a little closer to the "original") the natural color of collectible Cassida specimens?

There is no such method! But I think you can take a risk: try to fill the beetle in a transparent plastic like "plexiglass"... lol.gif

Keep out the light, I think.
That is, the box is not with glass, but with an opaque lid.

But the light has nothing to do with it. They "turn brown" almost immediately after soaking, and in species with silvery stripes on the elytra they disappear. Well, stripes-this, apparently, depends on the hemolymph (?). Somewhere I read that you need to soak in snuff (no kidding). No one tried it? By the way, this also applies to ladybirds.

Alas, it's not the effect of light. I kept mine without lights, in a tightly sealed tin box, and still they were irrevocably dimmed. Just, apparently, unstable pigments are destroyed over time. How not to preserve the pristine greenery of a freshly picked leaf...

You're right, the silvery stripes represent hemolymph circulating in the elytra. In any case, the soaking agent should never be ethyl acetate. It most destroys unstable pigments, primarily red and orange colors. Chloroform is best in this regard...

Oh, my God! I used to use ether for anesthesia (in the 70-80's and early 90's), and the color was often changed by leptures, paquitas, and so on. (not to mention the" rigidity " of the material). And since the late 90's, I started using ethyl acetate, and it seems to work better on "colored" barbels. And what else besides chloroform is possible? Don't talk about cyanides...

By the way, about cyanidessmile.gif
You can mash the leaves of bird cherry and put them in a stain (2-3 leaves). They contain enough hydrocyanic acid to kill a fairly large insect in a minute.

Ammonia. It is good at killing all beetles except dead eaters and skin eaters, and their lifestyle in places with high concentrations of ammonia probably affects them.
