Robberfly Insect FossilDescription: The Class Insecta is well represented in Liaoning and Hebei Provinces of China, with over 500 species referable to over 100 families based upon over 10,000 specimens. This fantastic diversity and exquisite detail is unprecedented throughout the world. This example is a member of the Asilidae, or Robber Flies. Modfern-day members of this family are predaceous, so perhaps these were as well. Diptera are quite uncommon specimens from the biota, so this is a most unusual fossil. This is a fine specimen with incredible detail preserved, particularly in the wings, from the dim past of 125 million years ago.
