Three-Lined Potato Beetle
A yellow-orange leaf beetle with three black stripes, resembling a smaller Colorado potato beetle. It feeds on tomatillos, ground cherries, and related plants.
Did You Know?
Like cereal leaf beetle larvae, its larvae pile their own excrement on their backs as a defensive shield.
Striped Seedcorn Beetle
A small, pale brown ground beetle with darker stripes on its elytra. It is sometimes a minor pest of germinating corn and other crop seeds, though it also eats many weed seeds.
Did You Know?
While it occasionally damages germinating crop seeds, studies show it consumes far more weed seeds, so its net economic impact on agriculture is actually beneficial.
