Grand Junction Robber Fly

*





Today on the bike path, I saw several robber flies on South Broadway
just before the path turns onto South Camp Road. A tiny toad 
was nearby, possibly after a few of the red ants crossing the path.




Robber flies are predatory creatures that capture other flying insects on the wing, hold them tight in their strong grip, pierce the victims' bodies with their sharp proboscis, inject the prey with a liquid
containing neurotoxins and proteolytic enzymes which quickly paralyzes the victim while it digests its innards. The robber fly then sucks out its newly-digested, high-protein, liquid meal. Yum!
