Dor Beetle
Main Characteristics of Beetles
- There are more than 380,000 species of beetles. They represent the most diverse order among insects.
- In the USA, there are 30,000 species. In Germany, there are approximately 7,000 species.
- Beetles have a head, six legs, two body parts, two antennae, two wings, and two wing cases.
- The wing cases are thickened and rest over the actual wings to protect them from injuries.
- There are beetles that glow due to a biochemical process: the fireflies. This phenomenon is known as bioluminescence.
- Beetles have a varied diet. Some species are herbivores, while others are carnivores. For instance, the bark beetle feeds on wood and bark, whereas the ladybug dines on aphids.
- Beetles communicate with their fellow species through scents, sounds, or vibrations.
- Beetles play a crucial role in nature. For instance, jewel beetles help pollinate plants. Ladybugs combat pests such as aphids. Dung beetles act like the health inspectors of the forest. They consume fresh dung and help prevent the spread of diseases.
- There are also beetles that are considered pests. These include the bark beetle, the Colorado potato beetle, and the woodboring beetle, whose larvae are also known as woodworm larvae.
- The largest beetles are the Hercules beetle and the titan beetle. They can reach a body length of up to 6.6 inches (17 cm). The smallest beetle is the featherwing beetle. It is also the tiniest insect. It measures just 0.01 inches (0.25 mm) in length.
- The heaviest beetles include the Goliath beetle, the Hercules beetle, the elephant beetle, and the titan beetle. They weigh between 1.4.-1.7 ounces (40-50 grams), with some reaching up to 3.8 ounces (110 grams). These fascinating creatures are found in Africa and South America.
- The tiger beetle in Australia is the fastest beetle. It can reach 8.2 feet (2.5 meters) per second. That's equivalent to 5.6 mph (9 km/h).
- The toughest beetle is the golden spider beetle. Some creatures were accidentally trapped in a container with thorn apple leaves and were found alive after 15 years.
