Types of Beetles in South Carolina

Save

South Carolina is home to a wide variety of beetles, and because the state exports nearly $1 billion in forest products every year, there is great interest in which ones are harmful and which ones are helpful to trees and plants. Some species aid in combating insects and pests that destroy trees and crops, while others are responsible for millions of dollars of damage.

Southern Pine Beetle

  • The southern pine beetle, which is only about one-eighth of an inch long, caused $125 million worth of damage in South Carolina forests in 1995 and 1996. The beetles destroyed thousands of acres of timber, feeding on trees that were unhealthy due to lack of water and nutrients in the area. Southern pine beetles range in color from red-brown to black and are considered the most destructive insect to threaten forests in the state.

Multicolored Asian Lady Beetle

  • Also known as the Halloween lady beetle, Japanese lady beetle, Asian lady beetle, and, simply, the ladybug, this insect is a biological control agent used to prevent other insects and pests from destroying crops. In 1979 and 1980, the United States Department of Agriculture (USDA) released large amounts of Asian lady beetles into Southern forests to combat insects that were destroying several types of trees. The beetles do no harm to humans, but if they sense danger, they release an odorous fluid from their legs that stains clothing and other surfaces.

Black Blister Beetle

  • The black blister beetle is so named because of its color and because the chemicals it secretes when it is pretending to be dead causes blistering on human skin. Its body is composed of three segments and has red-brown legs and short antennae. Black blister beetles eat the eggs and larvae of bees. To get into their nests, the beetles attach themselves to bees, are transported into the bees' nests, and then leave after feeding.

Asian Longhorned Beetle

  • This particular beetle made its way to South Carolina and other areas in the United States via packed raw wood materials from Asia. A wood-boring insect, it is known for causing damage to maple, sugar maple, poplar, willow, and elm trees. In China, the Asian longhorned beetle was responsible for damaging over 45% of its poplar plantations. Since the beetle's discovery on U.S. soil in 1996, the USDA has been researching ways to eradicate it before it can cause even more damage.

Tiger Beetle

  • A non-threatening insect, the tiger beetle is located in about half of all South Carolina counties. Known for its iridescent coloring, the tiger beetle is attracted to dry places with little or no vegetation, such as sand dunes. As it feeds on a range of insects, and not trees or plants, the tiger beetle doesn't damage its habitat. Appearing in the spring and fall, tiger beetles generally live about two years.
