Abstract: Hemithea aestivaria, “the common emerald” in Britain, is common throughout most of Europe and in Eastern Asia. The larva feeds on many herbaceous plants before hibernation and on a wide variety of woody plants in the spring.Forty of the distinctively-marked larvae were collected on cherry, apple, wild plum, and species of Rubus and Crataegus at Burnaby, New Westminister, and Langley, in British Columbia, between 1.IV.78 and 18.V.78. A sample reared produced a male that was identified by Dr. K. B. Bolte, Biosystematics Research Institute, Agriculture Canada, Ottawa, as of Hemithea aestivaria, a species and genus apparently not recorded previously from North America.
