Pillbugs can be distinguished from Sowbugs by their tendency to roll up into a ball when threatened. Sowbugs do not roll up. Both Pillbugs and Sowbugs are nocturnal and feed on decaying organic matter, such as leaf and flower debris. They do very little damage, if any, but may be considered a nuisance to African Violet growers. Distinguishing Symptoms Visible insects or other pests .
Isopods are gray in color with a shell-like body and have seven pairs of legs.
One common species, Pillbugs, will roll up into a ball when threatened. During the day, Isopods will generally take shelter beneath pots or among the leaf and flower debris that gather on the surface of the soil. If your Violet has this symptom, it is probably being visited by Isopods. The best treatment for Isopods is to simply remove them by hand. They are large enough to see and easy to find.
