With copper-colored wings and an emerald head, the Japanese beetle is pretty, but devastating.

The eastern Hercules beetle is one of the largest and heaviest insects in the U.S. In South Carolina, there is only one Hercules beetle species, Dynastes tityus. These insects are a type of beetle in the family Scarabaeidae – the same family as June beetles, Japanese beetles, and dung beetles.
Adults can be nearly 3 inches long and are a tannish to greenish color with black spots. Adult males have large horns on their heads, hence the common name rhinoceros beetles. Males with larger horns were able to obtain more nourishment as larvae. The horns are used when males “fight” to mate with females. Females do not have horns. Larvae are grub-like and can get as big as an adult’s finger.
These beetles are not pests, and little is known about adult feeding habits (though they have been observed to feed on tree bark and leaves). Larvae feed in rotting hardwood stumps and on dead leaves and other rotting material.
Despite their appearance, these beetles are not dangerous to people. That said, if you do pick one up, you might feel a little scratch from the small claws on the ends of its feet. However, they won’t bite you or jab you with their horn. Rather, if you’re lucky enough to see one, just enjoy the sight of one of the largest beetles in South Carolina!
With copper-colored wings and an emerald head, the Japanese beetle is pretty, but devastating.
What has got 6 legs, a head, 2 eyes and red wings and is not a dice game of Beetle. It is the red lily beetle Lilioceris lilii that consumes large quantities of one of our favorite plants.
The Asian longhorned beetle (ALB; Anoplophora glabripennis) is not easy to miss – adults of this large, black beetle with white spots, black and white striped antennae, and blueish feet are between 1 and 1 ½” long (Fig. 1). ALB larvae are equally striking as the large, white segmented larvae can be nearly 2” in length (Fig. 2). Established populations in the U.S. are found in Massachusetts, New York, and Ohio, and a new infestation was recently found in Charleston County, South Carolina.
A lot of attention recently has been on periodical cicadas, which are coming out of the ground after 17 years across parts of the Southeast and much of the Mid-Atlantic region. However, another insect is about to come out of the ground in South Carolina too, and this one is not just a novelty – it can completely defoliate many plants in your yard. That’s right, folks, it’s almost Japanese beetle season!
Few insects can grab your attention like a giant stag beetle. Stag beetles are in the insect family Lucanidae. Both females and males of many Lucanid species are impressively big, but the males, with their long mouthparts that look like antlers on a stag, are amazing and intimidating. While they are also called pinching bugs by some, they are quite harmless. The males have prominent mouthparts not to bite people but rather to impress females and to push, pull, and even throw rival stag beetles away from their future mate. Think of it as two bucks fighting over a doe in the forest.
The eastern eyed click beetle (Alaus oculatus) is found throughout South Carolina. Also known as the eyed elater, this is one of the larger click beetles in the region, with adults sometimes reaching almost 2” in length. They have two large black spots near their head that look like large eyes, which are thought to be for scaring away potential predators. Adults feed on nectar and are somewhat common around hardwood forest areas.
This is an Eastern garter snake. These nonvenomous snakes are pretty common in South Carolina and are active most of the year.
The light-colored tissue we see here is the result of squash beetle behavior known as “trenching.” Trenching cuts off (at least temporarily) the translocation of cucurbitacin defense compounds to preserve the palatability and quality of the squash foliage feeding site. The beetles in this particular field were sprayed and killed after trenching this section of the leaf, so the yellow tissue remains and was not eaten. Similar behavior occurs with other insects, such as dogbane leaf beetles.
This Napa cabbage is being fed on by larvae of both the yellow margined leaf beetle (YMLB, Microtheca ochroloma) and vegetable weevil (Listroderes difficilis). YMLB can be a significant pest for organic production, especially turnips and Napa cabbage, which they prefer.
These beetles were found under a decaying log in the woods. They are bess beetles, also called horned passalus beetles (Odontotaenius disjunctus).
These orange-colored things stuck to the bottom of a collard leaf are a cluster of lady beetle eggs. Lady beetles are great insects to have around, especially if you have problems with aphids, their favorite food. Adults eat aphids whole, while the nymphs, seen below, pierce and suck out the internals. We have numerous species of lady beetles in South Carolina that range in the number of spots on their back and color from red and orange to black. Read more here.
LIKE CLOCKWORK THEY START TO APPEAR ABOUT NOW: A first harvest of cucumbers, and also one of Japanese beetles. Into separate and quite different “brines” they go as fast as they develop, one a vinegar-salt formula, the latter a bit bubbly.
