It is so long since I posted anything that I have been struggling with getting the image re-sized but I think I have cracked it now. I have been trying out my new Canon 300mm F4 L IS lens over the weekend and took this image of a hoverfly on a berberis bush in my partner's garden.
Can anyone tell me what the blister like thing is on it's back?
Canon EOS 40D

Cropped in PSE8 (large crop)
All comments welcome

Hi Andy, the general composition is pretty good here however the depth of field is very limited, I guess you was trying to keep shutter speed up to handhold however this has affected the sharpnes of the hoverfly, this would have not been so bad if the fly had been side on or facing you however in this case it does not really work, sorry about that.

Andy, the 'blister like thing' is a scutellum See.

Thanks for the comments and thanks to David for the two links, they look very interesting. Must get out and practice on them, if only the weather would improve!

http://www.microscopy-uk.org.uk/mag/artmay07/cd-hoverflies.html don't ask me what its function as I haven't a clue, yet.
Be careful, photographing hoverflies can become addictive.
This is an interesting site, IMO. http://www.hoverfly.org.uk/
