Directions for site use:
You may navigate between categories by clicking on the desired category tab. Click on the appropriate tab to highlight the important stages of the life cycle for that category.
For more information about a stage of the life cycle, click on a yellow highlighted item. This will pop open a smaller window (similar to this one) containing pertinent information about the parasite, pictures or diagrams, or other information. Please be sure to close the pop-up windows using the 'Close Window' tab (as shown at above right) or by clicking the appropriate button in your browser to close the window; otherwise, you will be lost in a sea of small browser windows. For any uncertain terms, please see glossary for a definition.
