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.

13. Weevil

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. 

Moreover, adults are 3/4 to 5/8 inches long with white spots on the elytra (wing covers). The larvae are cream-colored with a brown head and brown antennae.

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. 

In Maryland, the drugstore beetle lives year-round and can infest various products. Products include cereal, flour, dried fruit, rice, spices, pet food, and tobacco products.

Also, they are known to infest items such as furniture, upholstery, clothing; woolen goods; carpets; curtains; books; and paper products such as cardboard boxes and old newspapers.

23. Giant Water Bugs Beetles

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. 

The larvae feed on roots, especially those of grasses and other broad-leaf plants.

Other tortoise beetles include the Mayflower Beetle, which is typically larger than the Golden Tortoise Beetle and more uniformly colored brown to black.

28. Seedcorn Beetle

Seedcorn Beetles are found throughout the United States and Canada and can be identified by the distinctive scarab-like shape on their back.

The Seedcorn Beetle is not a pest but a beneficial insect that helps control the corn earworm.

Coupled with that, this beetle lives for about five weeks, during which it feeds on corn plants. Females lay eggs at the base of the plant, turning into white grubs before pupating into adult beetles.

Meanwhile, our list of the different types of beetles in Maryland is not complete without the Seedcorn Beetle!

29. Seven-spotted Lady Beetle

Have you ever heard of the Seven-spotted Lady Beetle? Let me tell you about it. First, it is one of the types of beetles in Maryland.

They are active during the day but spend most of their time on the underside of leaves, where they are hard to see.

34. Soldier Beetle

Soldier Beetles are the most common types of beetles in Maryland and are characterized by their dark brown or black body with light brown heads. They can grow to be around 1-1/2 inches long, but they never get as large as some other types of beetles.

Soldier Beetles are mostly nocturnal, so they’re rarely seen during the day. You might find them on flowers or trees at night as they feed on nectar or sap.

Sometimes, these insects will congregate on windowsills or porch lights because they use light to navigate at night.

If you see these insects during the day, something is likely nearby that has attracted them – like rotting fruit or meat scraps!

35. Southern Sculptured Pine Borer Beetle

Southern sculptured pine borer beetle is a species of flat-headed wood boring beetle. This insect damages the pine trees by feeding on the sap and eventually weakening the tree.

The Southern Sculptured Pine Borer Beetle is found throughout the United States and Canada, with some populations extending into Mexico.

These are, however, peaceful types of beetles in Maryland. Squash lady beetles are not a pest and do not bite humans.

39. Stag Beetle

The stag beetle, one of the different types of beetles in Maryland, is a large and striking insect. It is easily identifiable by its long antennae, six-segmented abdomen, and distinctive black-and-white markings.

The male mandibles are much larger than the females. A mature stag beetle can measure up to 4 inches long. 

Plus, adult stag beetles feed on nectar from flowers, rotting fruit, tree sap, fungi, pollen, and aphid honeydew.

In the larval stage, they feed on dead animals such as mice or insects. They are nocturnal and hide in logs, under rocks, or bark during the day.

They are found throughout Maryland but prefer wetter areas like bogs and swamps with lush vegetation near trees where they can find food sources at night.

40. Strawberry Root Weevil

On the list of the various types of beetles in Maryland, the strawberry root weevil is a pest that feeds on the roots of strawberries.

In Maryland, they are typically found on strawberries planted in mid-June. The adult beetle is black and about 3/4 inch long. 

It is active from June to September, flying at dusk to feed and reproduce on other plants, returning to the strawberry patch at dawn. The female lays her eggs in the soil near the base of the plant and then dies shortly after that.

41. Strawberry Seed Beetle

The strawberry seed beetle is a reddish-brown, hard-bodied beetle about 2-3 mm long. It has a small head and long antennae that are nearly as long as the body. The larvae are about 1 mm long and covered with hairs, making them tiny caterpillars. 

Larvae are usually brown or black but may be green if they have eaten leaves from plants like clover or alfalfa. The larvae spend most of their time eating seeds on the ground.

To sum up, they can move quickly by flipping their bodies over to use their back legs to propel themselves away from danger.

42. Striped Blister Beetle

The Striped Blister Beetle is the most common blister beetle found in Maryland. It is black and orange with a yellow stripe down its back.

These particular types of beetles in Maryland are approximately 5 mm long. The larvae feed on decaying plant material, often found near rotting logs or fallen trees with fungus growing on them. 

They are often found during the daytime and can be distinguished from other types of blister beetles by their stripes.

The adults live for about one year and lay eggs that can survive up to four years in the soil until conditions are favorable for hatching.

This type of beetle has two generations per year, which means the adults will start to appear around May or June, then again around September or October.

47. Three-lined Potato Beetle

Speaking about the types of beetles in Maryland, this three-lined potato beetle is a small, black beetle with two red stripes on its wing covers.

It is most active during the night and feeds on leaves and other parts of plants. The adults lay eggs near the base of plants, where the larvae feed on plant roots. 

Infestations are often found around potatoes, but they can also be found feeding on beans, cabbage, corn, peas, and many other crops. The larvae feed for up to four weeks before pupating for about one week underneath soil or leaf litter.

The adults emerge from pupation holes near the base of plants and then fly off to find new food sources. They are generally only present for a few weeks each year during late spring through early summer periods.

48. Tormentose Burying Beetle

The various types of beetles in Maryland include the tormentose burying beetle. It is a member of the family Silphidae, which includes other sylphid-burying beetles.

This species is closely related to the burying beetle (Nicrophorus pustulatus) and the wood-boring urn beetle (Nicrophorus vespilloides).

The tormentose burying beetle’s larvae are similar to those found in other silphids. Moreso, they have been found to feed on small mammals such as rodents, rabbits, deer, and sheep.

The adults are obligate carrion feeders and scavengers that utilize dead animal carcasses for egg-laying sites. They have only been observed feeding on carrion once after it has begun to decompose.

49. Tumbling Flower Beetle

The tumbling flower beetle is a very small, shiny black beetle with orange or red markings on its wing covers. They are active between June and September and can be found in flowers during the day.

The adults feed on pollen but also nectar and honeydew, while the larvae live off of plant roots and decaying plant matter. 

Often, the adults are seen feeding on flowers such as petunias, tulips, hibiscus, sunflowers, roses, and dandelions. However, the larvae prefer to stay underground and chew through plant roots.

50. Twice-stabbed Lady Beetle

The Twice-stabbed Lady Beetle (Chilocorus stigma) is one of Maryland’s most abundant and easily recognized types of beetles.

These lady beetles are black with white spots and a wide, orange band across the middle. Uniquely, Twice-stabbed lady beetles are about a quarter inch long, including their antennae.

One way to identify them is by counting the number of spots on each wing – there should be 10 spots on each side for a total of 20 spots. Adults will have four black spots on their heads which form two pairs just behind the eyes.

51. Two-lined Leather-wing Beetle

By now, we know that there are many types of beetles in Maryland, including this two-lined leather-wing beetle (Atalantycha bilineata).

This is a species of leaf beetle belonging to the family Chrysomelidae. It is found across North America and has been reported as far south as Mexico. 

On the one hand, the larvae feed on plants, especially grasses and other herbaceous plants. And on the other hand, adults feed on leaves and flowers, but their feeding habits are not well studied.

52. Varied Carpet Beetle

The variegated carpet beetle is a small, common, and harmless insect that feeds primarily on woolen and other animal fibers.

They are found worldwide but are more prevalent in temperate climates like Maryland. Hence, they are one of Maryland’s more popular types of beetles.
