Interactive Key to the Aquatic Insect Orders of North America

This key is written in Lucid3.4. Lucid3 is a cross-platform implementation written in Java, and will run on any Java-enabled operating system (such as Windows, Macintosh, Unix and Linux, etc). You do not need to install any software on your computer to use Lucid3 keys on the Internet, but you may have to install the latest version of Java, if not already installed on your computer.

**New** Try the key in the new Lucid On-line Player - No Java required! Just browse and play the keys (adults, nymphs & larvae, pupae & nymphs).

Interactive Dichotomous Key to the Aquatic Insect Orders of North America

This key is written in Lucid Phoenix. Lucid Phoenix is a computer based dichotomous or pathway key builder and player that enables traditional paper based identification keys to be published on the Internet or CD. Like Lucid 3.4, Lucid Phoenix is cross-platform but requires the latest version of Java to run properly. See the Lucid website for more information.
