To collect samples for identification in the lab each course participant filled a a margarine tub with a little washing up liquid and left it overnight on the marshy edge of the Tarn. The next morning as we carried our tubs back to the Centre we met a group of walkers who were on the Pennine Way. They asked 'what are you doing? ' and our reply was ' we are bringing libations to the great god diptera!'
Another memorable activity was creating a matrix of different coloured washing up bowls on the lawn in front of the house - carefully making sure that no two bowls of the same colour were adjacent. We were investigating whether or not crane flies favoured a particular colour - they didn’t.
