Hello Liliane D,
a female
Calliphora vomitoria as prey of
Synema globosum (Thomisidae)
the anterior thoracic spiracle is usually infuscated (Rognes).
I think that light can alter the appearance of the infuscation.
see my attachment of microscopic differences based upon angle and lighting.
Best wishes,
John
