But nowhere near 2cm in length, I think. 1cm would be a big Pollenia.

Length of fly

Awkward because clearly can't go back to measure - but compare with speedwell flower? Maybe the 1cm is body length where I was looking at total length of fly - including the closed wings. Would that be the discrepancy?

1cm

The speedwell flower won't be over 1cm and the fly is only about the same length, so 1cm sounds reasonable. It honestly won't be longer, even with the wings.

So should I change the observation notes do you think? Concentrating so much on photographing fly (it kept moving from flower to flower) may well have thought it bigger than it was because looking through camera lens.

Change

No, I wouldn't change it. If you do, the comments discussion becomes out of synch with the description above. It's useful to have the discussion in relation to the original description...it's a common thing to do, overestimating size, and nothing to worry about.
