    Mosquito Life Cycle: How Long Do They Live?

    Mosquitoes are annoying and hazardous due to their disease transmitting bites. Thankfully in the mosquito life cycle, they have a short lifespan.

    Mosquitoes have been on earth for around 210 million years. Roughly 3500 species of mosquitoes plague our planet with no end in sight. To understand their lifespan start with the mosquito life cycle.

    4 Stages of a Mosquito Life Cycle

    • Eggs

    Stagnant water is the breeding ground for mosquitoes for laying their eggs. Whether it’s in your yard or your garden, if it remains undisturbed for a couple of weeks, the female mosquito will lay its eggs there.  

    Mosquito eggs need water for proper development. Initially, eggs are white but will turn black within a day resembling a speck of dirt. In favorable temperatures, eggs will take 1-3 days to hatch, and produce the mosquito larvae.

    Mosquito eggs can survive the harshest of winters. The eggs will wait to hatch when outside conditions favor them, even after a whole year.

    Female mosquitoes can lay up to 500 eggs in their lifetime.

    • Larvae

    Larvae are the baby mosquitoes also known as ‘wigglers’ because of their frantic twitching motion in the water. Mosquito larvae feed on microorganisms, algae, and bacteria which are available in aquatic conditions. Larvae are vulnerable during this stage and are at risk of predators like fish and birds.

    Cold-bodied mosquitoes require outside heat for their development. So, larvae will mature as quickly as the external heat favors them. Larvae develop within a week or so and continue molting (shed their skin) to develop into pupae. Larvae undergo four molting stages, and by the end of the last stage are around 1/4-inches long.

    • Pupae

    The pupae stage is the relaxing stage of the mosquito life cycle. In this phase, they don’t do anything except relax and swim around in the water. Just like larvae they live on the surface and take in oxygen through their trumpets. Pupae take almost four days to develop their tissues. They then slit open their cocoon, and emerge as an adult mosquito.

    • Adult

    The only purpose of adult mosquitoes in life is to mate and feed. They mate within a couple of days after coming out of their cocoon. Female mosquitoes mate only once in their life but can lay up to 100 eggs in one batch. Usually, they produce up to three sets of eggs before dying.

    Mosquitoes usually feed upon plant nectar, and fruit juices for nourishment. However, females also need protein for the development of their eggs, and they drive the protein from human blood. After a blood meal, female mosquitoes fly away to a warm place and rest there until their eggs are developed. After laying eggs, they fly again to hunt for blood and to nourish another set of eggs.

    Life Span of Mosquitoes

    The life span of mosquitoes varies between species. Some survive only in summer, and the moment winter arrives they die. Others hibernate in winter and have a longer lifespan. However, eggs of all mosquito species can survive in all weather conditions. Winter has no effect on them and will hatch in the spring after winter is over.

    Male mosquitoes die within five days after mating whereas female mosquitoes may live up to a month or two depending on the climate. Despite a short lifespan, the number of mosquitoes never decreases because of the immense reproductive ability of female mosquitoes.***

    Yellow Sac Spider Bite:

    Are Their Bites Dangerous?

    Unlike other spiders, Yellow Sac Spiders do not make or create webs, instead create sac silk in the path, which they travel in the daytime like in the corners of the wall, door opening, and wall joints. But what about their bites? Are they dangerous to humans?

    Amongst the wide range of species available on this planet, there is a great diversity of spiders. One of the common spiders found in the United States is the yellow sac spider. However, these creatures are located in very dark places like close boxes in houses and non-ventilated areas.

    Most of the time, these spiders can be found in an office, households, garage, and other closed areas to hide in cold weather. You can easily see them in the green grass during the summer season.

    Unlike other spiders, these creatures do not make or create webs, instead create sac silk in the path, which they travel in the daytime like in the corners of the wall, door opening, and wall joints. Female sac spider usually lays 30 to 48 eggs and put silk over them.

    Eggs are usually laid in autumn. The female may produce many eggs during her lifetime. Yellow sac spider takes shelter in flattened silk tubes during the day and moves out to hunt during the night.

    Yellow Sac Spider Identification

    Cheiracanthium inclusum and cheiracanthium mildie are two well known species of North America referred to as yellow sac spiders. An adult female sac spider body is typically 1/4 to 3/8 inches in length and its leg span is up to 1 inch. Males are more slender, with slightly larger leg span than the females. Moreover, its abdomen is pale yellow to light green in color.

    These spiders are usually small in size, and its body is yellow. Not always but in some rare cases, it is a mixture of yellow and brown, so people usually get confused to identify them with the brown recluse. As they are small in size, examining them is very difficult and may require a magnifying glass.

    Brown Recluse Spiders vs. Yellow Sac Spiders: What Is the Difference?

    While both yellow sac spider and a brown recluse have many things in common, it is very important for us to remember that a yellow sac spider bite is not so harmful.

    Identification of these spiders is essential. At first, you may feel like it’s a normal and harmless brown spider, but by distinguishing their characteristics, you can quickly identify them from their eyes and front legs.

    A typical brown recluse has six eyes arranged in pairs with one pair in front and a pair on either side whereas the yellow sac spider on the head has two rows of eyes, one row on top of the other with four eyes in each row.

    So in total, yellow sac spiders have eight eyes as compared to the brown recluse. Another characteristic is that the front legs of these spiders are a lot longer as compared to the other legs.

    What Happen When Yellow Sac Spiders Bite You?

    Yellow sac spiders are usually venomous and can bite if they get in contact with the human being. If they create a silken sac in between the human skin and bed sheets, then it can bite any human while sleeping, so these spiders are known as night-hunters as they go out for prey at night-time. They can also bite during daytime while a person is working in the garden.

    Whenever a creature bites human, there will be an effect on the body similarly when these spiders bit a human; it damages the skin cells leading to an inadequate blood supply, bacterial infection and traumatic injury.

    In the beginning, people misunderstand this damage by common infections of a spider bite. When they ignore the bite, the area becomes too itchy and then starts swelling slowly further leads to redness with a burning sensation.
