AMAZING! Fascinating little creatures. Wonder what the filled in colored cell on either side of the wings are for? Eyes - to make him appear bigger?

Thank you!
The filled cell called pterostigma. The functions of the pterostigma have not yet been established, but it is assumed that it is capable of extinguishing the "harmful" fluctuations of the wing during the flight.
Thank you, @photomax. Your answer was very informative right down to the diagram :) Amazing...nature.
