To move towards a better assessment of pesticide effects on non-target organisms, there is a need to perform a posteriori tests using relevant species. wetlands) but there are a couple of species which have only been seen a few times in the UK. Earthworm Identikit A. nocturna can be distinguished relatively easily as it is generally larger than A. caliginosa and has a deep red colour, but records of both species should be accompanied by a photograph where possible.
