Dear Daniel,
Thank you very much for the identification. At the risk of being greedy, could I also ask you to identify this lovely two tailed fly. Found near a stream in the same area, its wingspan and tails are about two and a half inches long.  What does it use these amazing tails for?

Hi again Peter,
This is a Thread-winged Lacewing or Ribbon Winged Lacewing,
Nemoptera bipennis.  We are not certain why the wings have evolved to have such delicate tails.

Dear Daniel,
Many thanks for this. It is wonderful to have your expertise available on the internet.
With bets wishes, Peter
