Maths Week Challenge

Today I took part in the maths week challenge. I answered all of the questions correctly.

The life cycle of a butterfly

First stage of life cycle of a butterfly

A female butterfly lays eggs

A butterfly starts its life as an egg, laid by a female adult

butterfly after mating. Butterfly eggs vary in size and shape, but most

are surrounded by a protective hard shell.

Example of butterfly eggs

Second stage of life cycle of a butterfly

Caterpillar hatches

A caterpillar develops within the egg and then eats its way out of

the shell. This stage of the butterfly’s life cycle is also called larva.

Caterpillar molts (sheds its skin)

A caterpillar spends all its time eating. As it grows,

the caterpillar becomes too large for its skin and molts (sheds

its skin) to make new skin. Depending upon the type of butterfly,

caterpillars molt four or five times.

Caterpillars spend all their time eating leaves

Third stage of the butterfly life cycle

Pupa and Cocoon

When the caterpillar reaches its final size it stops feeding.

The caterpillar wriggles and twists to gradually remove its old skin,

revealing a new protective skin called cocoon. Inside the cocoon, the

caterpillar changes into a worm like creature called pupa.

Steps of making the butterfly cocoon by the caterpillar

Example of a butterfly cocoon

Fourth stage of the butterfly life cycle

Adult butterfly

When the time reaches adulthood, the pupa changes into a butterfly

and leaves the cocoon. It pumps blood into its wrinkled wings and

expands them to their full size before flying away.

Pupa has turned into a butterfly inside the cocoon and slowly

coming out of it

The Life Cycle Of A Mosquitoes

Life Stages of Aedes Mosquitoes

 Eggs 

 Adult  female mosquitoes lay their eggs on the inner, wet walls of containers with water, above the waterline.  Mosquitoes generally lay 100-200 eggs at a time. Eggs are very hardy; they stick to the walls of a container like glue and can survive to dry out for up to 8 months— even over the winter in the southern United States.  It only takes a very small amount of water to attract female mosquitoes. Bowls, cups, fountains, tires, barrels, vases and any other container storing water make for a great “nursery.”

 Larva 

Larvae emerge from mosquito eggs, but only after the water level rises to cover the eggs. This means that rainwater or humans adding water to containers with eggs will trigger the larvae to emerge. Larvae feed on microorganisms in the water. After moulting three times, the larva becomes a pupa. 

Pupa 

 Pupae will develop until the body of the newly formed adult flying mosquito emerges from the pupal skin and leaves the water. 

Adult •

After adult mosquitoes emerge: male mosquitoes feed on nectar from flowers and female mosquitoes feed on humans and animals for blood to produce eggs. • After feeding, female mosquitoes will look for water sources to lay more eggs. • Aedes aegypti only flies a few blocks during its life.  Unlike other mosquito species, Aedes aegypti mosquitoes prefer to bite people. Aedes aegypti mosquitoes prefer to live near people. They can be found inside homes, buildings, and businesses where window and door screens are not used or doors are left propped open.
