At left are links to introductory and tool background information (available only from this page). "How to use this tool" covers important information about tool components, taxa covered, fact sheet content, and use of this tool's interactive key.

To begin an identification, first make sure your computer meets the Lucid3 "System Requirements." It is strongly recommended that you then read the "Best Practice Guidelines" for making an identification before actually using the key the first time.

To start the key, click either of the "START KEY" links. Note that the interactive key may be very slow (taking often up to several minutes) to open.

The navigation bar at the top of the page is on every Html page except the Entry page.
