Honeybee Life Cycle Sample

The diagram below shows the life cycle of the honeybee. Two things to consider are.

Complete Report

The diagram illustrates the various stages in the life of a honeybee. It can be seen that the complete life cycle lasts between 34 and 36 days. The trend suggests that there are five main stages in the development of the honeybee, from egg to mature adult insect.

The life cycle of the honeybee begins when the female adult lays an egg and the female typically lays one or two eggs every 3 days. Between 9 and 10 days later, each egg hatches and the immature insect, or nymph, appears.

During the third stage of the life cycle, the nymph grows in size and sheds its skin three times. This moulting first takes place 5 days after the egg hatches, then 7 days later, and again another 9 days later. After a total of 30 to 31 days from the start of the cycle, the young adult honeybee emerges from its final moulting stage, and in the space of only 4 days, it reaches full maturity.

To conclude, there are five main stages in the development of the honeybee, from egg to mature adult insect.

Silkworm Life Cycle Sample

The diagrams below show the life cycle of the silkworm and the stages in the production of silk cloth.

Complete Report

The first diagram shows that there are four main stages in the life of the silkworm. The trend suggests that the life cycle is based on a multiple-week period, after which the silk thread is produced into silk cloth. First of all, eggs are produced by the moth and it takes ten days for each egg to become a silkworm larva that feeds on mulberry leaves. This stage lasts for up to six weeks until the larva produces a cocoon of silk thread around itself. After a period of about three weeks, the adult moths eventually emerge from these cocoons, and the life cycle begins again. The cocoons are the raw material used for the production of the silk cloth. Once they have been selected, they are boiled in water and the threads are separated in the unwinding stage. Each thread is between 300 and 900 meters long, and they can be twisted together, dyed, and then used to produce cloth in the weaving stage. Overall, the diagrams show that the cocoon stage of the silkworm can be used to produce silk cloth through a very simple process.

Frog Life Cycle Sample

The diagram below shows the life cycle of the frog from the egg stage to an adult frog.

Complete Report

The diagram shows the life cycle of the frog from the egg stage to a fully grown frog. It is clear that there are six stages in the life cycle of a frog based on the information that is shown in this diagram. The first three stages show the frog in the early period of its life. The life of the frog begins at the egg stage. From the eggs, the frog then moves onto the embryo stage. The embryo stage shows the very early development of the frog from egg form to tadpole form. The embryos emerge from the eggs, with eyes, at a size that is a little bit larger than as it continues to develop. At the third stage, which is labelled as the tadpole stage, the tadpoles become longer and slenderer than right after the egg stage. In the last part of the tadpole stage, its legs breakthrough and are formed on the tadpole. In the next three stages, the frog emerges in a more familiar shape. In stage four the tadpole characteristics are now more frog-like, with the tail of the tadpole still remaining. At this stage, the frog is also now able to start pulmonary breathing on its own. At the final two stages, those being stage five and stage six, the frog develops into a tadpole frog, and then finally into a fully grown adult frog, thus completing the life cycle of this amphibian. To sum up, this diagram shows each of the six stages in the development of the life cycle of a frog.

Fly Life Cycle Sample

The diagram below shows the different stages in the life cycle of the fly.

Complete Report

The diagram shows the various stages in the life cycle of the mature female fly, from the egg stage to the full adult stage. It is clearly shown in this diagram that there are seven stages in the 2 to 4-week life cycle of a fully developed adult fly. At the first stage, the mature female fly lays eggs. These eggs last for only a relatively short period of time from 8 to 24 hours. These eggs then turn into larvae. There are 3 parts to the larval stages. At the first stage, the larva is short and plump. At the second stage, the larvae become longer and slenderer, and finally, at the third stage, the larvae are even longer and thinner. These three larval stages take about 4 to 7 days to develop. At the fourth stage, the larvae develop into the pupa. The pupa is much larger than the larvae, and this stage can last for the longest period of time from 10 to 20 days. At the end of the pupa stage, the young adult fly emerges. The diagram clearly shows that the young adult is much smaller than the fully formed adult. This transition from young adult to the fully formed adult occurs after the 20-day period of development has been completed. To sum up, the 2 to 4-week life cycle of the female fly has seven stages until its development has been completed.

Butterfly Life Cycle Sample

The diagram below shows the life cycle of the butterfly.

Complete Report

The diagram shows the 12-month life cycle of the butterfly. The trend suggests that there are 5 stages of the life cycle of this insect, from an egg, leading to the development of a fully-grown adult butterfly. At the first stage of this life cycle, an egg is laid on a milkwood leaf. 5 to 10 days later the egg is transformed into a larva. This is also called the caterpillar stage. The diagram shows significant changes in the development of the butterfly during this period of time. At the 3-week mark, the larva is changed into the pupa. The larva moults about 5 or 6 times during these weeks. The pupa can also be referred to as a cocoon. After stage three, the adult emerges from the pupa shedding it since it is no longer needed. For 2 to 3 weeks, the adult butterfly matures, and its life cycle will end after a period of 12 months. The butterfly increases in size quite a bit during these weeks, as is demonstrated in the diagram between stages 4 and 5. Overall, the life cycle of the butterfly lasts for a period of 12 months and has five stages of development as seen in the diagram above.

Salmon Life Cycle Sample

The diagrams below show the life cycle of a species of large fish call the salmon.

Complete Report

The diagram shows the complex nine-year life cycle of the salmon fish. The trend suggests that this life cycle has three main periods of approximated time, with salmon length measured in centimetres, from their birth to the end of their lives. The life of the salmon begins in the upper river with its slow-moving water. The salmon eggs are laid amongst reeds and small stones, and this cycle takes approximately five to six months. The eggs then transform into salmon fry with a length of 3 to 8 cms. These fry then go to the lower river with its fast-moving water. Here, at the second stage, the fry remains for approximately four years. From here the smolt, or slightly larger salmon, which are now 12 to 15 cms in length continues onto the open sea. In the open sea, the immature salmon remain for approximately five years. During these five years, the salmon fish grow to a length of between 70 and 76 cms. After this, the salmon then return to where they were hatched in the upper river, with its slow-moving water, and the life cycle repeats itself again. Overall, the diagram shows the nine-year life cycle of a salmon, from eggs to adult fish.

Sea Turtle Life Cycle Sample

The diagram below shows the life cycle of the sea turtle.

Complete Report

The diagram shows the steps involved in the life cycle of the sea turtle. The trend suggests that there are several stages in this life cycle. It is quite a complex life cycle, with adults living for up to 50 years, showing a long nesting period, and an even longer incubation and hatching period. The incubation and hatching period is shown in the first few steps. This process lasts for about 8 to 10 weeks. From here, the hatchlings forage the open ocean surface for food. This period of maturation lasts for 5 to 20 years. After this, the developmental migration period occurs when the sea turtles are between the ages of 30 to 50 years old. Before the mating begins, the immature and adult sea turtles forage along the shallow waters of the coastal region. The males continue to forage and migrate to and from the mating areas, while the females remain in the mating area. Once mating begins, the male and female turtles remain in the shallow water. When the mating has finished, the females then create a nesting area, and over a 2-week interval, the males migrate back and forth from the foraging area and the nesting area. The females also return to the foraging area during the nesting process, since the turtle's eggs must be incubated for many weeks by the female. After this, the hatchlings are born. Overall, the life cycle of the sea turtles involves many steps, over a long lifespan, with different roles being done by the males and the females.

Female Mosquito Life Cycle Sample

The diagram below explains the life cycle of the female mosquito.

Complete Report

The diagram shows the life cycle of the female mosquito. The trend suggests that the mosquito’s lifespan is 6 to 8 weeks and that each larval stage is bigger than the last, with moulting occurring between each stage all of which happen in water. At week one, the eggs are produced. By the second week, the first larval stage has occurred, and the eggs have now formed into a bigger larval shape. During week three, the larval have reached the third stage, once again doubling in size, with increased development on the larvae’s tip and tail. The same size increase and development of the larvae can be seen in the fourth and fifth stages. After week five, the larvae change into a pupa form with significant changes occurring to the mosquito’s development. By week six, the head and tail of the insect have formed, and once again the pupa is twice as large when compared to the previous stage. Weeks seven and eight show a fully formed female mosquito, after which the cycle repeats itself all over again. Overall, the female mosquito has a lifetime of six to eight weeks, with seven stages in its life cycle.

Fruit Fly Life Cycle Sample

The diagram below shows the life cycle of the adult fruit fly.

Complete Report

The diagram shows the life cycle of the adult fruit fly. The trend suggests that there are four main stages in the life of the fruit fly, with three periods of instar larval development, and the total life span of this fly is somewhere between 40 and 50 days. The first step shows the embryo stage on day one of the fruit fly’s life cycle. The embryonic stage shows the larva at its smallest and toward the end of the first day the instar larva begins to develop more. Instar is the phase between the period of molting of the fruit fly and it occurs within three stages of larval development. After three days, the second larval stage has been completed and the third begins. From two and a half to three days after the embryo stage, the third larval stage is complete, and the larva has now developed into a pupa with a noticeable eye, wing, and antennae development. Three and a half to four and a half days later the fruit fly has fully developed into an adult fly. The adult fly will live for up to 40 to 50 days. Overall, the fruit fly has four main parts to its life cycle with three stages of instar development lasting for a life span of 40 to 50 days.

Cicada Life Cycle Sample

The diagram below shows the life cycle of the insect known as the cicada.

Complete Report

The diagram shows the complex life cycle of an insect known as the cicada. The trend suggests that there are above ground and underground stages to the life of the cicada with the underground stage being more complex and much lengthier based on the stated time frame that is given in the diagram.

24 hours after emerging from the underground, the cicada will begin mating and oviposition which is the laying of eggs. The female lays the eggs in a groove on the tree and after a period of two months, the eggs will fall to the ground. After falling to the ground, the eggs then burrow themselves into it into the roots of the tree. During the nymphal stage, the cicadas feed on the tree roots for a period of four years. There are four instar stages while the cicadas are underground with two distinct cells, one being backfilled and the other being fed. This time underground can take as long as 17 years.

During the fifth instar, the cicada emerges from underground and begins a period of ecdysis which lasts for two months, from May to June. During this emergence, the cicadas shed their skin and after the mating and the laying of the eggs have been done 24 hours later the adult cicada with only live from five to six weeks.

Overall, there are two main parts to the life cycle of the cicada one that is aboveground and one that is underground.

Ladybug Life Cycle Sample

The diagrams below show the life cycle of a ladybug and its anatomy.

Complete Report

The diagram illustrates the life cycle and anatomy of a ladybug. It is clearly seen that its life cycle consists of four main stages starting life as an egg and finally becoming an adult, while its anatomy has eight main parts.

The life cycle of a ladybug starts with an adult ladybug laying eggs on leaves. The egg stage is for two to five days, and the egg develops into a larva and remains in the larval stage for 21 days. From the larva, the pupa is formed, and this stage lasts for seven days. This pupa then develops and matures into an adult ladybug.

As for the anatomy, a ladybug has eight main body parts. Its head has, not one, but two antennas, a pair of eyes and a protonum. The body of the adult ladybug is covered with red elytra and black spots. The wings and the abdomen lie under the red elytra. This adult ladybug has six legs with three of them on each of its sides.

Overall, the life cycle of the ladybug is characterized as having four stages and the anatomy of this insect is reported to have eight parts.

Flea Life Cycle Diagram Sample

The diagram below shows the life cycle of the flea.

Complete Report

The diagram shows the life cycle of the flea otherwise known as the Ctenocephalides Felis in Latin. The trend suggests that there are four stages to the flea life cycle adult, egg, larvae, and pupae mad the each one of these stages lasts from 1 to 2 weeks except for the laying of the eggs.

The adult stage is the only visible stage and makes up only 5% of the total population. The adult flea stays on the pet and a single female can produce thousands of eggs. Flea eggs are laid on a definitive host and then fall off into the environment as the animals move around. The eggs make up 50% of the population and hatch into larvae after 1 to 6 days.

The larvae feed on debris and flea feces in the environment. They develop into pupae after 5 to 11 days. Flea pupae have a sticky cocoon that makes them resistant to insecticides. Also, the larvae and pupae numbers represent about 45% of the population. The adult flea may emerge in 7 to 14 days or the pupae can stay dormant for months until the conditions are right for hatching. The now-adult flea immediately searches for a new host after hatching.

To conclude, the diagram shows four stages in the life cycle of the flea, from egg to adult.

Cockroach Life Cycle Diagram Sample

The diagram below shows the life cycle of the cockroach.

Complete Report

The diagram shows a cockroach’s life cycle. The trend suggests that there are two years to the life cycle of the cockroach, and during this cycle, each cockroach goes through four molts and eight stages from the egg sack to an adult insect. In the first two stages, it can be seen that the sack produce ootheca which are cockroach eggs, and these eggs are white. From the egg stage, the cockroaches develop into white hatchings and they then molt, losing their outer shell, transforming into newborn nymphs by stage three. By stage four, the hatchings have molted a second time and are now light brown early-stage nymphs. After a third molting, or loss of their outer shell, the nymphs are now at their mid-stage and soon after their late-stage. Their colour has changed a few times and the roaches have gone from light brown, to brown, to dark brown. Their shells have also thinned out and their legs and antenna have grown significantly. After a final molting process, the end-stage nymphs are adults and are ready for flight. Overall, during the two-year life span of a cockroach is goes through eight stages and half as many molts.
