The damsels we caught ranged from about 20mm to 40mm
The corixa are imature ones, hard to tell from the shots but most have yellow bellies
They were all between 5mm and 10mm. Mature ones have white bellies and are usually between 10mm and 12mm long.
The alder larva were between 15mm and 30mm long.
We were catching them for a reason
But all will be revealed towards the end of the month.
We have video footage of all the wee beasts, plus some of freshwater shrimps.As well as lots of stills.
If you can guess where its going you'll have a head start
