What Kind of Beetle Does a Grub Worm Turn Into?
Hello Alan-
Sorry I am seeing this so late. I am assuming you may have found answers by now. There are many kinds of grubs, but you may be referring to the Japanese Beetle Grubs. They can be bad news. They feed on the roots of turf grasses as grubs and eventually hatch into Japanese Beetles. https://www.extension.umn.edu/garden/insects/find/japanese-beetles/
Other than these guys, there are a variety of grubs out there. Cutworms can also be problematic in the garden, but they look more like little caterpillars. https://www.extension.umn.edu/garden/insects/find/cutworms-in-home-gardens/
Proper identification is important, whether you want to eliminate a pest or protect a beneficial insect. While I doubt that you are dealing with bee larvae, that is just one example of a beneficial insect which could be negatively impacted by a knee-jerk pesticide application. It is also important to note that you will have very poor results with pesticides if you don’t know exactly what your target insect is and when and how the chemical should be applied to combat it. Many, local extension agencies offer plant diagnostic clinics and pest identification services. You might check with your closest university to see if they provide such services.
