A Robber Fly With A Grasshopper

By | August 29, 2020

I spotted this Robber Fly with a Grasshopper on an Arkansas Country Road I like to walk near my place in the Ouachita Mountains.

The Robber Fly attacks its prey by injecting it with saliva containing neurotoxic and proteolytic enzymes. The Robber Fly then sucks the liquefied material from it.
