LIFE CYCLE OFA BUTTERFLY

STAGE 1:BUTTERFLY EGGSA butterfly starts life as a very small,round egg. The egg shape dependson the type of butterfly that laid theegg. Butterfly eggs are usually laid on theleaves of plants.

STAGE 2: LARVAEThe eggs will hatch into tiny larvae

called caterpillars. Caterpillars eat a lotof leaves so that they can grow. Theyeat non-stop to gain more energy for

growth. Their body covering is hard

(exoskeleton) and does not stretch orgrow so the caterpillars must moult

several times to shed their old skin inorder to grow bigger .

STAGE 3: PUPAAs soon as the caterpillar reachedtheir full length, it will form a pupa.During this stage, the pupa doesnot eat and move. A greattransformation is happening insidethe pupa !

STAGE 4: ADULTThis transformation is known as

metamorphosis and the adultbutterfly will emerge from the pupaafter some time. At first, the wings

would be folded and soft. Thebutterfly will start pumping blood

into its new wings to get themworking. Once its wings are strongenough, the butterfly will fly away

in search of food.

LIFE CYCLE OFA COCKROACH

STAGE 1:COCKROACH EGGSThe cockroach life cycle starts with eggs.Generally shaped like a kidney bean orpurse, the egg case is either carried by themother or placed in a protected locationuntil hatching.The female deposits the eggcapsule in a protected location preferablynear a food source.

STAGE 2: NYMPHNewly hatched cockroaches come outfrom eggs as nymphs. During this stage,the insects grow by shedding their skinmultiple times until reaching adulthood,a process known as moulting. Aftereach moulting, the nymph grows in sizeand length.. Nymphs look alike to adults except thatthey do not have wings yet.

STAGE 3: ADULTWhen a cockroach is at the adultstage, it stops moulting anddevelops a pair of wings.Once they reached adult stage,they will look for a mate toreproduce. An adult female can lay300 - 400 eggs in its lifetime.

LIFE CYCLE OFA FROG

STAGE 1: FROG EGGSFrogs are amphibians, which meansthat they can live in water or on land.They go through several stages ofdevelopment before they becomeadult frogs and during its youngstage, they live only in water.A frogbegins life as a fertilized egg. Afemale frog lays a lot of eggs at onetime in a pond. The eggs float onwater in a jelly cluster. The eggs willsoon hatch into tadpoles!

STAGE 2: YOUNGWhen the tadpole hatches, it doesn’thave any legs! It has gills that allow it tobreathe underwater. The tadpole swims,eats plants and algae from the water,and grows for several weeks.During thistime, the tadpole starts to develop lungsso it will be able to breathe out of thewater when it becomes a frog. Thetadpole starts to grow two front legs andits long tail becomes shorter and shorter.The tadpole uses the nutrients stored inits tail as food, so until its tail iscompletely gone, it doesn’t needanything else to eat! Then just a littlestub of its tail is left, and the tadpole is ayoung frog. It hops right out of the waterand onto dry land for the first time! Thefrog is still very small.. .

STAGE 3: ADULTThe adult frog breathes with lungsand has no tail. The frog will mostlylive on land and eats insects andworms. Later these new frogs willmate and the whole life cyclebegins again.
