Are they mating or is one eating the other? Interesting common name, do you know its origin?
The title said it...lunch!.
To quote from 'British Soldierflies and their allies' (Stuubs and Drake 2001) "The name robberfly aptly conjures up the image of the highway robber, ready to pounce on the unsuspecting victim. These are powerful insects with sharp piercing mouthparts that are fatal to other insects..."
A fascinating family of large, striking flies.
