Phellus olgae : the monster robber fly.

[wollastoni]

Talking about the huge Thai robber fly I have found on Phiphi island, my friend Joe Bugeja informed me of this Australian species : Phellus olgae

This Asilidae is so big and powerful, it must hunt even big insects like butterflies or dragonflies.

The asilids you have mentioned are fearsome hunters, it must have been a sight to see on your recent trip. It makes me glad I'm not on that rung of the food chain, although olgae might be a solution to the camel problem in Australia  Congratulations on your photography skills, you have posted some nice shots!
