http://gahsha.notlong.com 25 June 2008 Bug. This ubiquitious bug is seen throughout the garden, but predominately on the potatoe leaves. I notice this bug when squashing the few Colorado Potato beetles present. There are not many, and the bug moves quicky, so it is necessary to clap the hands together and squash leaf and bug. The shell casing is very hard, and it takes considerable force to squash. I muse about whether I should be concerned about its destructive habits; if any, which are not readily apparent.
