Household beetles Insects in the City

house beetles identification

A drain fly is a furry flying bug with a gray or brown-colored body and wings covered in long, thin hairs. A characteristic habit of drain flies is how they fold their wings over when at rest. Red milkweed beetles belong to the insect family Cerambycidae, or longhorn beetles. As the name suggests, the identifying characteristic of the red and black longhorn beetle is its long, arching, segmented black antennae. With red milkweed beetles, the black antennae are close to the eyes—a unique feature of these beetles. The common cardinal beetle (Pyrochroa serraticornis) looks completely red apart from its legs and antennae.

Key points to help in identifying household insects

Looking at close-up pictures of this brown beetle, you’ll see that there are light-yellow tufts of hair on its body. Apart from being tiny insects, the brown beetles have a similarly shaped body. However, biscuit beetles don’t have serrated antennae or smooth wing coverings like the cigarette beetle.

Looking up close at pictures of black carpet beetles you may notice that they are covered in tiny hairs. The ninebark calligraphy beetle is a shiny bright red leaf beetle with black spots, stripes, and curved patterns on its wing covers. The red and black insect has a shape like a ladybug and measures 0.23” to 0.27” (6 – 7 mm) long. Its distinctive domed body, red antennae and legs, and black thorax and head make it easily recognizable. The red milkweed beetle is a type of brightly red-colored longhorn beetle with black spots. Other distinguishing features of the black-spotted red beetle include its black underside, legs, and long, curved antennae.

Bed Bugs (Cimex)

You’ll often find the wasp-like beetle feeding on flower nectar during summer. Pennsylvania ground beetles are a type of black or metallic green carabid beetles with brown legs and antennae. Identifying features of the mid-sized beetles are their ridged elytra, spiny legs, and depression on their thorax. There are over 400 species of beetles in the genus Harpalus, and they can be bronze, green, or black. Pedunculate beetles are classified as ground beetles because they burrow into the soil.

Cockroaches are small household bugs with a distinctive reddish-brown, flattened oval body, six spiny legs, and a pair of characteristic feelers. The most common roach is the German cockroach (Blattella germanica) which is light brown with identifiable tan stripes on its back. The bright red scarlet lily beetle has an elongated oval shape and shiny red elytra. However, other parts of the beetle are black, including the undersides of its wings. Looking up close, you’ll notice the red insect has a slim thorax compared to its broad abdomen.

Fruit Flies

While cockroaches don’t give people diseases through bites, they can transmit food-borne illnesses from one place to another. They can also trigger asthma “because of a protein in their saliva, droppings, and on their body,” Troyano says. Carpenter ants can bite, and they’ve been known to break skin when they do, which can be painful.

Flour Beetles

Apart from their black color, you can identify black beetles by their hard shell, antennae, and pincers. Black beetles that invade homes tend to be smaller in size than the ones you may find crawling around your yard. The grapevine beetle is another of the types of June beetles in the family Scarabaeidae and subfamily Rutelinae. This scarab beetle is light orange or pale auburn in color with black lines dividing the wing covers and thorax. Its other name, ‘spotted June beetle’ comes from the 4 dots on the side of its body.

The hermit flower beetle is a large, shiny black scarab beetle commonly found throughout North America. The dark mahogany brown or black beetle has a shiny oval body that is slightly rounded. Because of its distinct leather odor, it’s also called the leather beetle. Black beetles are a common type of insect that are found in our homes and backyards.

What Are the Most Common Small Flying Beetles in the House?

This beetle species has earned the notoriety of feeding on prescription drugs. One thing you need to know about skin beetles is that it doesn’t refer to a specific type of beetle but a whole category. One clear disadvantage of having rice weevils is grain loss due to their continued feeding action. Here, we discuss varying household beetles commonly found in households. If you’re faced with a beetle problem, any of these will likely be among them.

Rice weevils (Sitophilus oryzae) and maize weevils (Sitophilus zeamais) are very similar in appearance to granary weevils. One of the differences is that rice weevils are smaller, and their reddish-brown bodies have orange markings. On the other hand, maize weevils are larger than grain or rice weevils. However, there are several differences between the two types of beetles. For example, the merchant grain beetle flies, whereas the sawtooth grain beetle is a non-flying insect.

Spiders are common household pests that come in all shapes and sizes. Typically, spiders are easy to spot due to their eight spindly legs, rounded body, and lack of antennae. Brown or black house spiders can be furry or have smooth bodies and measure up to 0.8” (20 mm) long. To identify a cockroach or a beetle, you should look at the shape of the body. Beetles are smaller insects with a harder body and are usually black “bugs.” On the other hand, roaches are brown bugs with long, slender antennae. To accurately identify bugs in your house, it’s vital to look at the insect’s size, shape, number of legs, and if it has wings.

However, they are hard to spot in gardens as they prefer to hide in curled leaves and under flowers. Ladybugs are easy to identify with their domed red wing covers and black spots. As their name suggests, red pumpkin beetles primarily feed on pumpkin leaves. However, the pesky orangey-red bugs cause plant damage at all stages of their lives. The red adult beetles devour plant leaves and can defoliate plants.
