NOTES ON UTAH LACHNEA (APHIDIDAE)1
Published online by Cambridge University Press: 31 May 2012
Extract
The hypothetical ancestor of the Aphididae was probably a large generalized form, always winged, both sexes occurring in each generation, and with only a few generations each year. Migration would be lacking, and the development of the aphid ancestor would probably be tied up with one of the primitive types of plants occurring in that early period.
