Key to Genera

The key to genera assumes you have a twig girdler. Before you start the key to genera, please visit the Twig Girdlers page to confirm your specimen agrees with the characterists listed in the diagnosis. Also, the key assumes that you have access to a dissecting microscope with strong lighting. This is needed in order to see the morphological details such as eye shape, size and position.
