Hi Jimbo

According to Jacob Kahn, cubutal index is totally dependent on genetics but discoidal shift can be influenced by environmental pressures. This suggests to me that cubital index should be given more weighting than DS. I have tested wings (using DrawWing and Morphplot) for a number of people including someone with bees on a pensinsula in Wester Ross. On that basis these are the best I have come across so far:

The first was a swarm collected from a feral colony in Wrexham and the second is a managed colony in an apiary in Nottinghamshire where no bees have been added for 41 years. Neither are 100% but they are the best plots I can offer. I am trying to find the origin of the Nottinghamshire bees but I cannot get earlier data than South Derbyshire in about 1970. Does anyone know if Galtee were exporting bees then?
