Life Cycle of the Butterfly

Habitats of Butterflies The extaordinary habitats of butterflies can be quite diverse. Many different species of butterflies can be found all over the world and in various climates such as deserts, mountains, and coastal regions. They thrive in these areas due to the fact that they need sun and warm climates to survive. They will even migrate from areas when it cools and return when it warms up again. All these areas contain essentail living and non living components that allow butterflies to adapt. There are many resources that are needed in a butterfly’s habitat such as warm air teperatures, water, plants, flowers, and fruits. You can usually find adult butterflies flying around flowers and fruit plants eating nectar. They use a straw-like beak to consume liquids which is what they prefer. These plants rely on the butterfly in order to pollinate other flowers to reproduce. Butterflies also drink water from ponds, lakes, puddles, or other water source. They will hide between rocks, in blades of grass, or under a leaf for protection. The adult female butterfly will eventually lay eggs to start the life cycle process and carry on their species. There are four stages in this incredible process.

Life Cycle: Stage One Stage One of the life cycle process begins with the female adult butterfly laying eggs. Where the eggs are laid depends on the preference of food desired by each species. Some will attach their eggs either on top or underside a plant leaf, others will lay them on top of flower petals, the stalks of plants, or the area between the stem of a leaf and the stalk. These are known as host plants. These are plants that they enjoy eating and will supply a sufficient amount of food for the catepillar that will be available once they hatch.

Life Cycle: Stage Two Stage two of the process consists of the larva or catepillar. After about five days of developing in the egg, the larva emergers and will it eat its own egg casing. After this It will continuously eat and sleep. The catepillar will consume the leaves around it and will shed its skin or molt several times and become bigger. It will continue for about 10 days until it matures enough to enter the third stage of the process.

Life Cycle: Stage Three The third stage of the life cycle of the butterfly consist of the catepillar encapsuling itself in a silky cacoon. After shedding multiple times it will attach itself and hang upside down to just about anywhere it finds acceptable. This can vary and can range from places such as a stem of a plant to a window sill of a home. A CHRYSALIS or PUPA will cover the catepillars entire body. For approximately ten days Inside the hard casing of the cacoon, the catepillar will transform itself into a butterfly. At the end of the process the CHRYSALIS will turn dark and transparent. This is will now lead into the fourth and final stage of the process.

Life Cycle: Stage Four In the final stage of the process the beautiful adult butterfly emerges from the cacoon. When the butterfly first comes out it is not able to fly just yet. The wings are damp and aren’t able to work properly. It takes a couple hours for them to completely dry in order to prepare for flight. Once they are airborne they will then go and find food and help flowers pollinate. Soon the process will start all over. Although there are several species, there are still great threats to butterflies. The most threatening is the loss of habitat due to a rise in urban and agricultural development as well as climate change.

Life Cycle of a Frog

Habitat of a frog Thousands of species of frogs can be found all over the world and are very important to the ecosystem. Since they are amphibians, they live near water sources such as ponds which allow them to breed. It also provides have a variety of food sources. However, there are some species that dwell in deserts and others that live in trees. Since they feed on bugs they assist with keeping the insect population down.

Life Cycle: Stage One The first step in the life cycle of frogs is laying eggs. This is also known as SPAWNING. The male will climb on to the females back. While she is releasing eggs in the muddy banks of water sources or in the water itself, the female will release a mass of eggs. Some species will lay thousands at a time. This is due to the fact that not all the eggs will make it. As the female releases the eggs the male will fertilize them. The embryo’s begin to develop inside their gel-like sacks. Soon, they grow into baby tadpoles you can see swimming inside their egg. They will hatch anywhere from 6-21 days depending on the type of frog. Most parents will leave the eggs to survive on their own after fertilization has taken place.

Life Cycle: Stage Two The tadpoles that hatched are very underdeveloped. They mainly consist of weak gils, a mouth, and tail. It will eat the yolk of its own egg at first for food. After a few weeks of development, It will be able to swim around the water eating off of small plants, grass, and algea. They use rocks and plant life to avoid threats of being eaten by other animals. Around week four the frog begins to mature even more as it begins to grow small teeth and the gils begin to grow skin over them. The tadpoles begin to resemble a frog around 9 weeks. The tadpole becomes elongated and begin to grow legs and a larger head. However, it will still have a tail. It is now known as a Froglet. The food source will change from algea to small insects.

Life Cycle: Stage Three Stage three of the life cycle is where metamorphosis occurs. The process starts at around 9 weeks and takes approximately 4 weeks to fulfill. It will begin to molt or shed its skin. The froglets will begin to resemble a frog more and more as the mouth and legs become more developed and its tail begins to dissipate. During this process the lungs mature and function. The frog is able to breath oxygen.

Life Cycle: Stage Four After approximately three months from spawning, the completion of the life cycle has been attained. The once tiny tadpole is now considered an adult frog. It will now live and hop around on land close to the water to keep its skin moist. It can now also inhale through its nostrils to retrieve oxygen to its fully developed lungs. The frog will continue to consume worms, flies, and other small insects with its now widened mouth and long, sticky tongue. Once they have matured enough they will then go find their way back to the water to mate and start the whole process over again.
