[Note Guidelines] Photographer's Note
This is (or was) a Robber Fly.

Robber flies (Asilidae) are one of the main predatory groups of the Diptera (Two-winged insects). Many of these predators are opportunists; they wait on a perch for prey tems to fly past and then grab them. This means that a large range of prey may be eaten.

This fierce, merciless predator has, however, met his match in the form of a fungus which has invaded his body, killed him and finally completed its own development outside the fly's body.

The two cream, mushroom-like growths from the thorax and the long root-like tendril at the rear are the external signs of the fungal infection.

It is a remarkable fact of life in the forest that even the fiercest of predators can fall victim to the unexpected.

Wow Alan,

amazing subject. However, in terms of capturing the image I would've chosen another, more englobing, POV.
tfs, Betty

Just amazing, most interesting and direct to my FAVS.
Did you know that some of this fungus can rule the behaviour of the host? Have a look here, not my best shot, but a nice read :) http://www.treknature.com/gallery/Europe/Spain/photo4022.htm
Best regards, Felipe.
