Hoverfly

I think. It was so huge that I thought it may have been a hornet, but I looked it up and think it is a hoverfly. I have posted 2 extras to help in case anyone is an expert on such matters! 
It was enormous. This was taken with my 18 - 300 mm lens which (somehow) I had set on 1.3x so it looks as though it may have been cropped. It hasn't, and is SOOC.
