Threespotted flea beetle
The potato flea beetle is a small (0.065 inch), shiny black beetle. The threespotted flea beetle is two to three times larger and has an orange-colored thorax on which are three prominent dark spots. The palestriped flea beetle is about twice as large as the potato flea beetle. It is dark brown and has a longitudinal creamy white stripe on each wing cover. The tuber flea beetle is about the same size as the potato flea beetle and is also black and somewhat shiny, but has even rows of small indentations on the wing covers. All of the flea beetles have enlarged hind legs and jump vigorously when disturbed, thus the name flea beetle.
