If you've ever found a small, shiny black beetle in your home or yard, you might be wondering what kind of beetle it is. There are many black beetles, and most pose no threat to humans or other animals (beetles are one of the most popular creatures on earth). However, some can damage wood and starchy foods like grains, so it's good to know what kind of beetle you're dealing with.
There are more than 400,000 species of beetles on the planet, making them the most diverse group of organisms in the animal kingdom. Even within the United States, there are an estimated 18,500 species. Out of all those species, only the black ones tend to invade homes and yards and crawl up walls and ceilings, scaring away people and pets alike. Because black beetles are so common in many areas worldwide, it's essential to know how to identify them so you can take action if they're found in your home or yard.
Beetles come in all shapes and sizes, with varying lifestyles and behaviors. However, these common black beetles are some of the most recognizable species in the U.S. They can often be found in homes or yards throughout the country. Read on to learn about 40+ common black beetles and what you can do to help keep them out of your home or yard.
First, a Quick Science Lesson: What Are Beetles?
Beetles can be found in nearly every habitat, from the Arctic tundra to the rainforests of South America. Beetles are also incredibly diverse in appearance, with some species looking like tiny insects and others resembling large and colorful animals.
Despite their diversity, all beetles share a few common features. Most notably, they have a hard exoskeleton and two pairs of wings. The front pair of wings is hardened and serve as a protective cover for the hind pair of wings used for flight.
Beetles also have chewing mouthparts and powerful mandibles that allow them to feed on various plants and animals. Thanks to their adaptability and versatility, beetles have been incredibly successful, making them one of the most abundant groups of animals on earth.
Interesting Facts About Black Beetles
There are several interesting facts about black beetles that many people may not know. Here we will share a few of these fun beetle facts:
Black Beetles Can Fly Long Distances
Black beetles can fly long distances due to their unique physical attributes. Their wings are specially adapted to aerodynamic flight, and their muscles can generate high levels of force. Additionally, black beetles have a high metabolic rate, which allows them to generate the energy needed for sustained flight.
Their large wing area also helps them stay airborne for extended periods. All these adaptations combine to let black beetles fly great distances without tiring. Consequently, they can disperse over broad areas and colonize new habitats.
Black Beetles Get Attracted to Light
Black beetles are attracted to light because they use light as a navigational cue. The beetle uses light to orient itself and determine where it needs to go. Additionally, the light may also attract mates for the beetle.
Black Beetles are Excellent Swimmers
For several reasons, black beetles are excellent swimmers. Their streamlined bodies minimize drag as they move through the water, and their strong legs provide powerful strokes. In addition, black beetles have special paddles on their hind legs that help them steer and change direction.
These adaptations make black beetles well-suited for life in aquatic environments. As a result, they are often found near ponds and waterways, where they play an important role in the food chain.
Black Beetles can Survive a Long Time Without Food or Water
Black beetles can survive for long periods without food or water, thanks to a few adaptations that have allowed them to become one of the most resilient insects on the planet. For example, their exoskeletons are extremely tough and impermeable, preventing them from dehydrating in arid conditions.
They can also enter a state of suspension called diapause, which essentially shuts down their metabolism and allows them to live off stored fat reserves. In some cases, black beetles have been known to survive for over a year without food or water.
These adaptations have allowed black beetles to thrive in a wide range of environments, making them one of the most successful insect species on the planet.
How to Identify Different Types of Black Beetles?
There are many different types of black beetles, and it can be challenging to identify them all. However, a few key characteristics can help you identify different types of black beetles.
- First, look at the size of the beetle. Black beetles come in various sizes, from very small to very large.
- Second, look at the shape of the beetle. Black beetles can be oval-shaped, round-shaped, or elongated.
- Third, look at the beetle's legs. Some black beetles have long legs that they use for running, while others have short legs that they use for crawling.
- Finally, look at the beetle's coloring. Some black beetles are entirely black, while others have patterns of black and brown on their bodies.
By considering these key characteristics, you should be able to identify most types of black beetles.
Common Types of Black Beetles in Your Home, Garden or Yard
Black beetles are a type of insect that can be found in your home, yard, or garden. While most pose no threat to humans or animals, some can damage wood and starchy foods like grains, so it's good to know what kind of beetle you're dealing with.
