Finding invertebrates can be difficult in the winter but ground beetles were still plenty.
Its always better if pupils can use the equipment themselves to investigate.

The beetles were trapped over several nights ,by me, using jam jars as pitfall traps I then tipped them into basins in the workshop for the pupils to investigate.
Devils coach horse beetles (Ocypus olens ) were quite numerous in the traps. The weather had still been mild for November ( bats were still out) Buglife.org.uk suggests that they mate in the autumn and if the weather remains mild can survive the winter as the adult stage.
It was obvious to the children that they were carnivores taking the heads off the other ground beetles
