2. Only two eyes
One of the most striking features of house spiders is that they have only two eyes. This is in contrast to most other spiders, which have eight eyes. The two eyes of house spiders are located on the front of their cephalothorax, and they provide the spider with a wide field of view. Despite having only two eyes, house spiders are able to see quite well. They can detect movement and objects in their environment, and they can even see in low-light conditions.
The fact that house spiders have only two eyes is significant for a number of reasons. First, it helps to distinguish house spiders from other types of spiders. Second, it gives house spiders a unique advantage in their environment. Because they have a wide field of view, house spiders are able to spot prey and predators more easily. Additionally, their ability to see in low-light conditions gives them an advantage over other animals that are active at night.
The unique eye structure of house spiders is a fascinating example of how animals have adapted to their environment. By having only two eyes, house spiders are able to survive and thrive in a variety of habitats.
3. Not venomous
House spiders are not venomous, which means they do not have fangs that can inject venom into their prey. This is a significant fact for several reasons.
First, it means that house spiders are not a danger to humans. They cannot bite or sting, and their venom is not harmful to humans. This is in contrast to other types of spiders, such as black widows and brown recluses, which can deliver painful and even dangerous bites.
Second, the fact that house spiders are not venomous means that they have to rely on other methods to capture prey. They do this by using their webs to trap insects. Once an insect is caught in the web, the spider will inject it with a digestive enzyme that liquefies the insect’s insides. The spider then sucks up the liquefied insect.
The non-venomous nature of house spiders is a fascinating example of how animals have adapted to their environment. By not relying on venom to capture prey, house spiders have been able to survive and thrive in a variety of habitats.
4. Live up to two years
The fact that house spiders can live up to two years is a significant aspect of their biology and ecology. It is one of five key things to know about house spiders, as it highlights their relatively long lifespan compared to other spiders and insects.
The extended lifespan of house spiders provides several advantages. First, it allows them to accumulate knowledge and experience over time, which can help them to be more successful predators and avoid predators. Second, it gives them more time to reproduce, which can help to increase the population of house spiders.
The long lifespan of house spiders also has implications for humans. For example, it means that house spiders can be more difficult to control, as they can survive for longer periods of time without food or water. Additionally, it means that house spiders can be more likely to transmit diseases to humans, as they have more time to come into contact with pathogens.
Overall, the fact that house spiders can live up to two years is a significant aspect of their biology and ecology. It provides them with several advantages, and it also has implications for humans.
5. Beneficial predators
House spiders are often viewed as pests, but they actually play a beneficial role in the environment as predators of insects. By eating insects, house spiders help to control populations of pests that can damage crops, spread disease, and annoy humans.
One of the most important insects that house spiders eat is the mosquito. Mosquitoes are known to transmit diseases such as malaria, dengue fever, and yellow fever. By eating mosquitoes, house spiders help to reduce the risk of these diseases being transmitted to humans.
House spiders also eat other insects such as flies, cockroaches, and moths. These insects can spread bacteria and other contaminants that can cause illness in humans. By eating these insects, house spiders help to keep our homes and workplaces cleaner and healthier.
The predatory behavior of house spiders is a key part of the ecosystem. By eating insects, house spiders help to control populations of pests and reduce the risk of disease transmission. This makes house spiders a beneficial part of the environment.
6. Unique sensory hairs
House spiders have unique sensory hairs on their legs that allow them to detect even the slightest vibrations in the air. These hairs are so sensitive that they can even detect the footsteps of a human walking several feet away. Spiders use these sensory hairs to locate prey, avoid predators, and navigate their environment.
The sensory hairs are arranged in rows on the spider’s legs. Each hair is connected to a nerve cell that sends signals to the spider’s brain. When a hair is stimulated, it sends a signal to the brain that tells the spider the direction and intensity of the vibration.
Spiders use their sensory hairs to locate prey in a variety of ways. For example, they can use their sensory hairs to detect the vibrations of a fly walking on a leaf. Once they have located their prey, they can use their sensory hairs to track the prey’s movements and pounce on it.
Spiders also use their sensory hairs to avoid predators. For example, they can use their sensory hairs to detect the vibrations of a bird or other predator approaching. Once they have detected a predator, they can quickly run away or hide.
