Maryland has some of the most diverse beetle populations in the United States, ranging from giant water bugs to ground beetles to metallic green tiger beetles.
This guide will help you identify all the different types of beetles in Maryland and then tell you what kind of habitat they prefer and what they feed on.
Whether you’re looking to attract them to your garden or keep them away from your crops, this guide can help you identify which ones pose the biggest threat.
And in addition to that, it entails how you can protect yourself against them if necessary. Let’s discover the various types of beetles in Maryland.
1. Ground Beetle
First up on our list, the Ground beetle is one of the most common types of beetles in Maryland. Ground beetles are known for their distinctive black and yellow markings on their bodies. These markings are typically very visible on the head, thorax, and abdomen.
Unlike other types of beetles, they do not fly but move quickly across the ground using their long legs as a mode of transportation.
A ground beetle’s diet primarily consists of other small insects, such as flies, ants, snails, or slugs which it will use its strong jaws to catch and consume.
They can be found just about anywhere, from woodlands to fields or even residential yards. Just anywhere, there is plenty of vegetation for them to hide under during the daytime hours.
2. Black Firefly
The black firefly, also known as the common Eastern firefly (Photinus pyralis), can be found throughout the United States and Canada.
They are a beautiful greenish-yellow color with black stripes across their body. The adults like staying close to the water and not flying more than 200 feet from it.
These particular ones are the most common types of beetles in Maryland that live near water, although other types of fireflies also live near water.
3. Dogbane Leaf Beetle
The dogbane leaf beetle is a tiny, dark brown one with distinctive orange markings on its back. The larvae can be found feeding on the roots of plants in the dogbane family (Apocynaceae). The adults feed on leaves and flowers.
Often, they are attracted to plants with bright coloration, like those in the milkweed family (Asclepiadaceae).
These types of beetles in Maryland are found throughout the state and thrive in habitats ranging from forests to meadows.
4. Beetle Grub
The beetle grub is a type of beetle larva that is typically found in the soil. The grub will create tunnels and can be found moving around at night.
They have segmented bodies, spines on their back, and a pointed heads. Their diet includes decaying organic matter.
Moreso, these beetles are well known for their long antennae, which they use to find their way around. They are the types of beetles in Maryland that are blind because they don’t have eyesight.
In Maryland, the most common type of beetle grubs is June beetles (Lucanus capucinus), Japanese beetles (Popillia japonica), as well as May bugs (Phyllophaga spp.).
5. Convergent Lady Beetle
The Convergent Lady Beetle is a prominent species that are commonly seen during the spring and summer months. Adults are typically orange with black spots but may also have red or yellow markings.
The Convergent Lady Beetles are types of beetles in Maryland that can be found on various plants. This makes them a good choice for organic pest control.
The adult convergent lady beetle preys on aphids and other plant-sucking insects like leafhoppers, scale insects, spider mites, and whiteflies.
6. Black Vine Weevil
The black vine weevil is a pest that can be found on plants like grapevine, hops, and morning glory. It is about 1/4 inch long and has brownish-black coloration with a yellowish-white underside.
The adult’s mouthparts are located at the end of its snout to make it easier for them to feed on plant juices.
That aside, adults will lay eggs during the summer months, which will hatch into larvae after three weeks or so. These larvae have a dark head capsule and a light body that grows until adulthood.
7. Calligrapha Beetle
Calligrapha is a genus of leaf beetles. The calligrapha beetle has a black head, thorax, and elytra, while the abdomen is brown with black bands. It measures 2 to 3 millimeters long by 1 to 2 millimeters wide.
This species is not very well known, but it is still one of the different types of beetles in Maryland and Pennsylvania. George F. Atkinson first described it in 1884.
8. Cocklebur Weevil
The cocklebur weevil is a common pest that feeds on cocklebur, which is poisonous to most animals. Cocklebur contains toxic substances called pyrrolizidine alkaloids, which are poisonous to cattle and other livestock.
These insects are not harmful to humans unless they are eaten, but they can cause allergic reactions if touched.
To reduce the risk of exposure, it is best to wear gloves when handling these beetles. Cocklebur weevils are very small, with dark brown heads and bodies that range from 1-2 mm long. Most importantly, they aren’t left out of our list of Maryland’s various types of beetles!
9. Dark Brown Click Beetle
The Dark Brown Click Beetle is a ground beetle that can be found throughout the Eastern United States. They are typically found under rocks, logs, and leaf litter. Adults are brown or black with red stripes on their backs.
Additionally, the larvae are white grubs that can grow to about 3 centimeters long. These types of beetles in Maryland feed on other insects, such as caterpillars and grasshoppers.
10. Metallic Green Tiger Beetles
Like others, the metallic green tiger beetles are types of beetles in Maryland. These beetles are typically found on red maple trees.
Moreso, they are dark green with bright metallic green spots. The body length of this species can reach up to 2 inches, and the wingspan can be as wide as 2 1/2 inches.
11. Water Penny
Water pennies are so named because they are often found near water. They are typically red and black, with a black head, thorax, and red abdomen. They range from 1/2 to 1 inch in length.
Furthermore, the females lay eggs underwater, which means that the larvae develop underwater as well. Larvae usually hatch after three or four weeks and can live up to nine months before they pupate into adults.
12. Water Scavenger Beetle
Next to be discussed on our roll of the different types of beetles in Maryland is the water scavenger beetle. This is a small brown to a black insect that can be found all across North America.
The beetle’s diet includes decaying plant matter, such as leaves and wood, but they will also eat other insects.
Typically, the water scavenger is less than one inch long and has a short antenna. They often live near water sources and are attracted to light at night. This can make them seem like they’re flying around your porch lights at night.
Weevils are often characterized by their long snouts resembling worm-like tubes. Weevils are not only types of beetles in Maryland; they can also be found worldwide and come in many shapes and sizes.
They are most commonly recognized for their small, slender bodies, which have a protective outer shell that is usually shed as the beetle gets bigger.
Some common weevils include the rice weevil (Sitophilus oryzae), granary weevil (Sitophilus granarius), maize weevil (Ceutorhynchus cribricollis), and the curculio beetle (Conotrachelus nenuphar).
14. White Oak Borer Beetle
The White Oak Borer Beetle (Goes tigrinus) is a dark brown beetle with a black head and thorax. The underside of the beetle is white with black spots on it.
Primarily, it can be found under oak trees and bore into the tree to lay its eggs. The eggs hatch, and larvae eat their way out from the inside. This is not left out of our role of the numerous types of beetles in Maryland!
15. White-spotted Sawyer Beetle
The White-spotted Sawyer Beetle, Monochamus scutellatus, is one of the popular types of beetles in Maryland found throughout the state. It lives on the ground near seepages and streams, where it eats decaying vegetation.

16. Fire-colored Beetle
Certainly, Fire-colored beetles are one of the most common types of beetles in Maryland. They have a black head and prothorax, and their elytra are red with black stripes.
Besides, these beetles can be found under logs, stones, or other debris during the daytime. They may also be attracted to lights at night.
17. False Potato Beetle
The false potato beetle (Leptinotarsa juncta) is a large and common pest of potatoes, tomatoes, eggplant, and other related plants. The adult is about 8 mm long and has a black head with white dots on the front.
The body is orange-brown with black stripes running the length of the elytra. Black spots are on the sides of the abdomen.
Also, the larvae are orange-brown but have four dark stripes running down their back. They are covered with short hairs from head to toe, giving them a rough appearance.
This type of beetle lays its eggs singly or in small clusters on leaves near the ground or on plant stems at the soil level.
18. Emerald Euphoria Beetle
The emerald euphoria beetle is a small, slender beetle with a green body. The head and the thorax are black, and the elytra (wing covers) are semi-transparent green. The antennae are also black.
In addition, males have a tubercle on the prothorax, which is absent in females. Emerald euphoria beetles are one of the different types of beetles in Maryland that can be found throughout but prefer to live near water sources. This is where they feed on dead plant material, spores and algae.
19. Elderberry Borer Beetle
Still on our list of the various types of beetles in Maryland, we have the Elderberry Borer Beetle and Desmocerus palliatus.
It is a native beetle found throughout the Eastern United States. It has a glossy black body and is about two millimeters in length.
The head and thorax are reddish browns with white spots; the abdomen is yellow with black stripes. Coupled with that, females lay eggs on the bark of elderberry trees, which hatch into larvae that tunnel under the bark.
The larvae feed on sapwood and can eventually kill the tree. They pupate within burrows in the wood or under loose bark before emerging as adults to mate and fly to other elderberries to lay eggs.
20. Eggplant Flea Beetle
The eggplant flea beetle is one of the most common pests, of the types of beetles in Maryland, to affect eggplants.
They lay their eggs on the undersides of leaves, which hatch into larvae that feed on the plant’s leaves and flower buds.
Additionally, the larvae are small, yellowish, and worm-like, with a dark head. These pests can cause considerable damage to plants if left untreated because they eat away at eggplant foliage and flowers.
21. Dung Beetle
Dung beetles are insects that are types of beetles in Maryland and can be found in other parts of the world. Dung is a term for feces, which these beetles eat and use to create their nests. Dung beetle species can vary between regions too.
In North America, there are two main types of dung beetle: the dung-rolling scarab (Scarabaeus) and the burrowing dung beetle (Onthophagus).
The dung-rolling scarab is often called a white-scarred beetle. This is because it is white with black or brown markings on its back, including elytra and pronotum.
22. Drugstore Beetle
This list of the numerous types of beetles in Maryland is not complete without the drugstore beetle. This is a small, 1/8-inch (3.2 mm) long oval-shaped beetle that is brown to dark-brown colored and has black spots with white tips on its wing covers.

The giant water bug, Lethocerus americanus, is one of Maryland’s most common types of beetles. These large bugs can grow up to 7 centimeters long.
They are brown with green stripes on the body and head, making them easy to spot when they fly or crawl around.
Furthermore, the giant water bug feeds on other insects and invertebrates, such as tadpoles, frogs, newts, fish eggs, snails, and slugs.
Females lay clusters of eggs on vegetation near water sources or at the edge of ponds, where they will hatch and drop into the water below.
24. Scarlet Lily Beetle
Native to Europe, this beetle was first documented in the United States by a scientist named Harris, who found it near New York City. The scarlet lily beetle is so-named for the bright red and yellow colors on its body.
Meanwhile, this coloration serves as a warning for predators that the scarlet lily beetle is not edible.
Besides this bright warning, this beetle does not have any distinguishing features from other types of beetles in Maryland.
25. Scarlet Malachite Beetle
The Scarlet Malachite Beetle has a black head and thorax with a bright red abdomen. They are usually about 2 cm long, making them the longest type of beetle in Maryland.
They’re most active during the summer months and can be found on plants that have been damaged by insects or other animals, such as aphids.
Proceeding, the female will lay her eggs near aphid colonies, and larvae will feed on the insects before they pupate into adults.
Scarlet Malachites need to be close to their food sources because they have poor mobility and can’t fly. Unlike other scarlet-colored beetles, this species is not toxic to humans or animals.
26. Sculptured Pine Borer Beetle
The Sculptured Pine Borer Beetle is a common insect encountered in Maryland. It is a brown beetle with two thin yellow stripes that run down the length of its wing covers. These stripes are not always visible but can be seen when the wings are lifted at rest.
The Sculptured Pine Borer Beetle uniquely gets its name from its habit of attacking pine trees and turning them into giant sculptures. They will carve out the bark and eat the wood underneath, leaving intricate patterns on their canvas.
Beware if you have one or more of these types of beetles in Maryland living near your pine trees! It might be time to start looking for ways to get rid of them before they do too much damage!
27. Golden Tortoise Beetle
The Golden Tortoise Beetle is a small, black beetle with orange-brown markings on its elytra. The larvae are black and wingless, and adults are active during the day and feed on leaves.
