June 10-15, Ryazan region.

Group A. Day butterflies
1. Hawthorn Aporia crataegi? A very large butterfly relative to our other whiteflies. Meadow near the village, feeding on Carnation-grass.

2. Tyria jacobaeae? If it is, I found its caterpillars there last year. A field overgrown with young pines.

3. In the garden, feeding on Veronica longleaf. Golubyanka same?

4. Also in the garden, collects moisture from the soil, stubbornly did not want to fly away, apparently very thirsty tortured)

Group B. Nocturnal butterflies. All were shot in the same biotope-a light pine forest with an undergrowth of sedge and raspberry.
5. Moth Cabera pusaria?

6. I fell right under my feet from a nearby pine tree. She posed so that you could take her in your arms. The wingspan is 51 mm. Hypomecis punctinalis?

7. In terms of behavior - the exact opposite of the previous one: being startled out of the grass, she ran around the forest with incredible speed and hare maneuvers, changing parking several times

8. A very beautiful contrasting moth, and was found-sitting on a raspberry leaf. Patiently allowed herself to be molested)
Is this also H. punctinalis?

9. Found sitting on the forest floor.

10. There are no options, except for Epirrhoe rivata...

Such variations are found in all green butterflies from scoops, take for example Calamia tridens, Staurophora celsia, I have completely yellow ones. And Chloeporinae, where this is strongly observed, Pseudoips prasinana, Bena bicolorana have strongly yellow variations. In Nacna malachitis from Acronictinae, yellow variations are even more common than green ones. Just a variation of this, it is unlikely that someone specifically discolored it

Most of these color variations are caused by exposure to an aggressive external environment, and it does not matter in nature, in a stain or in a box. Most of these color variations are in boxes. In nature, they are very rare and again often associated with external factors, not genetics.

Yes, this is not done on purpose, on the contrary, it is quite difficult to preserve the green color in a number of species.

Not everything is so sad. Yes, where butterflies come face to face with anthropogenic territories, human pollution, mutations, color changes occur, and all this is temporary, until the environment is restored.
For the most part, this is just a protective coloration, mimicry under the state of the environment, and it is precisely laid down genetically. For example, autumn coloring, take the same green scoops, different moths, in summer and autumn they have different shades and colors. This is their protection, disguise for the color of autumn. For the collection in boxes, you need to take proper care, maintain lighting, the right humidity and temperature (which I'm currently doing by the way

), by 90%, or even more, you can save collections for many decades. My collection includes very well-preserved specimens of several species of Coenonympha caught back in 1896 by visiting German entomologists in our region, and they have not lost their color at all.

I fully agree with you that the green pigment of many moths is one of the most unstable. I know this in my own practice, and therefore I do not use ethyl acetate, ammonia, or even stains in the classical sense to put green lepidopters to sleep. Just freeze them in the freezer, and then, after thawing, straighten them out. In this case, the color of green butterflies does not suffer at all, unless, of course. in the future, keep the boxes in a dark place.
The shuttle that caused the discussion had an unusual yellow-brown color already at the time of arrival in svetolovushka. This is accurate, since it was obtained by me personally during a field trip. The color change could really be related to the weather features of the current year, which in our area are manifested in abnormal heat and 3 months .drought: the background grass cover has dried up and turned yellow-brown. Perhaps the insects also began to "switch" to the appropriate protective color.

This is good when you live and fish not far from home. On long trips, in the field, you can't take the freezer with you when you're away for a week or two, unless you have a cool car with a built-in freezer

. You can use instead of any alcohols, saturated saline solution, acts a little longer than alcohol, also well and without consequences on the appearance of the butterfly. Ether is a good thing, but many people can't get it, I finish off my stocks from the 90s. The best way out, still a shot of ammonia, enough microdose, it will not affect the color of the butterfly's wings.
