I ask: What is the percentage of melanotic specimens? And if having the dark color gives the advantage of warming up to the sun faster, what disadvantages does it have? (less camouflage?). Thank you in advance. Fabius

Hello Fabio the percentage of melanotic or melanic individuals is not always the same but varies according to the geographical area of the different populations. In some cases it exceeds abundantly 50% of the specimens present in a given portion of the territory in other cases they are very rare, sometimes only melanotic can be observed. Most likely the percentage is strongly conditioned by climatic and environmental factors such as climate and altitude, in alpine regions rich in precipitation there has been a greater presence of dark specimens. Certainly the black color favors thermoregulation and rightly as you say to the disadvantage of camouflage what are the evolutionary conclusions is not yet clear, as it is not yet clear the abundance of concolor specimens in certain populations
