Extract
The Iowa Insect Survey has, for more than ten years, been studying the seasonal and geographic distribution of Iowa insects. The records are card indexed and come from various sources, chief of which is the survey collection made up by frequent collecting trips covering the entire state. In this way at least some preliminary work has been done in each of the 99 counties of Iowa. Many of these counties have been rather thoroughly worked for special groups.
