"This report grows out of studies begun in the fall of 1926
when the writer was first impressed with the abundance and
variety of the fall and winter stonefly population in Illinois.
Field observations coupled with the rearing and collection of
stoneflies were focused from 1926 to 1929 chiefly on our fall and
winter fauna, resulting in the publication by myself in 1929 of a
detailed report concerning the ""Fall and Winter Stoneflies, or
Plecoptera, of Illinois."" After the appearance of this paper attention
was directed mainly to the species constituting our spring
and summer stonefly fauna and a minimum of effort and time
has since been spent in study of the fall and winter species.
The present paper, then, is a summary of our stonefly studies
which have been more or less continuous since 1926. For completeness
this report has not been limited to the spring and summer
forms but includes an entire survey of the plecopteran fauna
of Illinois, which makes it possible to present a classification unrestricted
by the seasonal idiosyncrasies of species, genera or
families. It offers, too, an opportunity to add further data concerning
some of the fall and winter species not available at the
time of the 1929 paper, and perhaps most important, it enables
the presentation of a balanced and comparative picture of the
stoneflies of this state."
