This aquatic insect data base has been compiled over 40 years, using information provided by various members of Trout Unlimited, Ed Haaga and "Cap" Buettner, customers of the old Orvis Pole & Paddle Shop, fishing companions, E-mail messages from our 'on-line' friends, and my streamside notes and observations. Also used were various journals, dairies and numerous books of reference. Updates continue today with changes in taxonomy and/or new data. This db was formated first on index cards, then to Appleworks, FilemakerPro 4.0, MS Access, HTML , Online Web Publishing using FMP 10.0 and now FMP 12.0.
In spring of 2012, 24 species of Dragonflies and 2 species of Damselflies were added to the DB that we believe have sufficient populations in Wisconsin trout habitat, both moving (lotic) and still (lentic) waters to impact fishing.

Though taxonomy of aquatic insects remained static for a long period of time, the last several years have seen incredible changes. The following database lists use the older Latin names (as you will find in most of the literature) with synonyms appearing in brackets to the right.

Common names are used in both the emergence calendars and the database records. The latin tags are used as the cross links for clarity. In taxonomy, FAMILY/SUBFAMILY are always presented in capitals. Names at the Genus level only have the first letter Capitalized and names at the species level use no caps at all. In the database records all are in capitals for the ease of viewing.

Note: EDO and LDO stand for Earliest Date Observed and Latest Date Observed.

Also in the lower right hand corner, the numbers represent the month(s) that the insect is present as an adult, the letter A is the first two weeks of that month and B is the last two weeks of that month.
