Golden tortoise beetle
The golden tortoise beetle has a beautiful transparent shell with three layers that fill with red pigment when it finds a potential mate. The golden tortoise beetle is distributed widely in eastern North America, west to about Iowa and Texas. Golden tortoise beetles feed on foliage.
These creatures are not present in large enough numbers to do serious damage to your garden, but they can chew plant leaves. You have to make sure that your plants are properly watered and fertilized, and that the planting area is clean and free of weeds. You can remove them just by hand without pesticides.
