Laphria
Those knobs surrounding the tail end are pretty diagnostic for that genus of Asilid, especially if it is in wood

More info?
Can you give us a size estimate? Do you have any other images showing the mouthparts or a closeup of the anal spiracles? Those characters largely determine what family a given fly larva belongs in. My initial guesses would be a crane fly larva (the wood-boring genus), or a Laphria robber fly larva.

Sorry
Approximately 15 mm long. Unfortunatly I don't have any other images. I assumed it may not be identifiable without a detailed head shot. I suspected crane fly or laphria, but I don't know much about flies. More likely crane fly as the log was along a wet pond margin.

It is less likely
to be a crane fly larva since the tail end is too pointed to house the spiracles and spiraclar lobes which usually are found on the posterior end of crane fly larvae. That is if the visibe end on the image was the tail end - Chen
