Aphids are tempting subjects for investigation because they are often
abundant, easily found, and unlikely to run away, and because of
intriguing facts about their biology such as polyphenism,
parthenogenesis, gall formation, and the production of a soldier morph.
However, until now identification has presented a severe challenge to
the beginner, because there are so many rather similar species, many of
which have several different forms. The authors make this much needed
Naturalists' Handbook accessible by confining themselves to aphids
leaving on broad-leaved trees. This has reduced the problems of
identification to manageable proportions and should encourage more field
studies of this important and ubiquitous group of insects.
