An account is given of a severe attack to grassland by chafer‐beetle larvae in some north Wales valleys in the years 1942‐3. The species concerned were Phyllopertha horticola L. and Hoplia philanthus Fuess. Estimations of the populations of both species were made and notes are given on the biology and comparative morphology of their immature stages. Both species have a one‐year life cycle; all stages of Hoplia philanthus occur somewhat later than Phyllopertha horticola.
