This dichotomous key can be used to identify most of the common insects found in Goldenrod Ball Galls.
To use the key, simply click on the choice that corresponds with the most correct description.
Follow the links from page to page until you reach an endpoint, which should be the name of the insect found within the gall.
In the event that you find an empty gall, the key will help determine what happened to the fly larva.
Once you have identified the contents of the gall (or the animal that killed the gall fly larva), you can get more information by clicking on its name.
