Hi Nikita,
Although the first question was meant for Kahis I have looked for information on this subject:
Hackman (1958) writes:
O. florum: The commonest species of the genus.
O. punctella: Less common than florum but with almost the same distribution in Finland.
As to your second question:
Of all the specimens of
O. punctella I have seen (not all that many!) there was only a single male specimen. However from those results I would not say that males are less common than females. It may be true though.
