   I travelled to my bird friend to look for stag beetles (Lucanus cervus) which are very very rare in Poland. Friend lives in place where there is one of the biggest population of this beetle in country. Stag beetle has it's swarming time, so the best moment to have a chance of finding it.
   It was a great success *_*
