Sites B and C, 1973 and 1975 



The distribution of hind-femora lengths for all stages, caught and reared, from 

 both sites and for both years combined, are shown as histograms in Fig. 4. The 

 close similarity of the clustering to that seen for site A indicates that again a five- 

 stage history predominated. In 1973 two individuals from site B had hind-femora 

 measurements that, combined with wing structure, distinguished them from the 

 main clusters. One of these was identified as a four-stage type when the antennal 

 segmentation was taken into account. No segmentation was recorded for the 

 other, but the appearance of reversed wing-buds on moulting from a nymph with
