Differences in egg colour among European sawfly species were known for many years, but no use of the information in basic taxonomic work was attempted, and there was little application in practical keys or identification tables. The egg colours of North American sawflies were unstudied, except for an occasional, casual reference to the colour in an individual species. The work reported in this thesis represents the first attempt to study sawfly egg pigmentation in an objective manner, and to apply the findings to taxonomic research, as well as to provide data for use in identification aids. The analytical methods were adapted from other fields, but it was necessary to carry out tests to make certain that confidence could be placed in the results, because the conditions in the present study were not identical to those in the work from which the methods were derived.
