A Little Bit Scary

Hostile aliens are among us.

A war is being waged, and the number of victims have been staggering.  

The reports are true:

they stab their victims with their needle like tongues,

inject enzymes that paralyze their victims and liquifies their organs,

and then they suck it all up.

Slurp.

It's time to panic, folks.  Head for your bomb shelters and basements!  What is the government doing about this?!

Oh, what?  These aren't hostile extraterrestrials that have come to feed on our organs?

These are actual real BUGS?!

Phew!  Well, at least we humans don't have to worry!

I guess I can't say the same for all of the normal prey that a Robber fly stalks, like bees, dragonflies, grasshoppers, and wasps.  Robber flies often take on animals that are larger than themselves - there have even been reports of robber flies attacking hummingbirds..

Robber flies are important for controlling the populations of various insects that they eat and thus can often be considered beneficial (depending on what they are eating).  

But still a little bit scary,

don't you think?
