Soldier Fly

Sorry. I don't know enough to go further on identification.
Anyway, it's worth considering sexual dimorphism and development phase within a specie to assign variations you could see.

Thanks Andre and John for the help. To me there is a difference in the colour and shape of the abdomen tip, this one being orange and conical almost to a point and the other one is dark and much blunter. Is there any significance in that?

I agree with John La Salle. :)

My guess is the same given for one of your previous spotting, since I think they are the same specie. http://www.projectnoah.org/spottings/184...

I hope this helps.

This is a fly not a wasp.
I am guessing a soldier fly (Stratiomyidae) - although always better to have a fly person pitch in.

There is an easy way to distinguish them (if you ignore exceptions). Flies have only a pair of wings and not two pairs as other insects.
