The black of the remainder of the abdomen is broken only by a fine light line at each abdominal segment joint. The flanks of the thorax are sky blue. Sexually immature males vary in colour.

If only larvae were as easy to identify! Not that adults are always easy but definitly easier than larvae I think! I've got loads of larvae waiting to be identified from a pond survey carried out last year. We've done most of the other inverts but keep avoiding the odonata as they are too tricky!
Have a look at my website, you will find a larvae section which might help you, regards Chris.
Thankyou very much! Looks like it could be useful. So many books seem to deal only with adults and I'm never sure how reliable most internet sources are!
