1 The Life Cycle of a Butterfly Life CyclesThe Life Cycle of a ButterflyThe Life Cycle of aFrog
2 The Butterfly Life Cycle Stage One: Egg StageStage Two: Larva StageStage Three: Pupa StageStage Four: Adult Butterfly Stage
3 Stage One: The Egg Stage Eggs are laid by the female on a foodplantThey are abandoned by the parentAround five days later, a tiny, wormlike creature will hatch
4 Stage Two: The Caterpillar Stage The egg hatches into a tiny larva, called a caterpillarThe caterpillar has biting jaws and legsThe caterpillar eats and grows a tremendous amountThe caterpillar sheds its skin in order to grow
5 Stage Three: The Pupa Stage The caterpillar attaches itself to twig and forms a hard outer shellInside the pupa, or chrysalis, the caterpillar changes into a butterflyPupas are often camouflaged to hide from predatorsThis process usually takes about two to three weeks
6 Stage Four: The Adult Butterfly Stage The butterfly is ready to emerge when the pupa skin is translucent, showing the coloring of the wings beneathThe pupa splits and the limp, damp butterfly emergesA little warming in the sun and the butterfly is ready to fly and mateThe adult butterfly only lives for a short timeThey cannot eat, they only drinkThe adult female butterfly lays eggs that have been fertilized by the adult male butterfly.The Butterfly Life Cycle starts all over!
8 Stage One: The Egg Stage A female frog lays eggs in waterThe male frog fertilizes the eggs as soon as the female lays the eggsThis large bunch of frog eggs is called frog spawnA large spawn of eggs is laid because many of the eggs do not survive and grow into adult frogsThe eggs will hatch between 6-21 days of being fertilized
9 Stage Two: The Tadpole Stage A tadpole wriggles out of each eggAt first, the tadpole breathes and moves like a fishThe tadpole has gills and a long tailAfter five weeks, the gills disappear and the tadpole develops lungsBy seven weeks, the tadpole eats insects and plantsLegs begin to sprout and arms grow
10 Stage Three: The Froglet Stage By ten to eleven weeks, the front legs have appearedAt twelve to fourteen weeks, the tail disappearsThe tiny froglet can leave the waterThe froglet is almost a mature frog, about 2-4 months oldThe froglet still has some of its tail
11 Stage Four: The Adult Frog Stage The tail has disappearedAn adult frog may live up to three yearsAdult frogs catch and eat insects with their long sticky tongueThey can also eat small fish and wormsAdult frogs hibernate during winterThe adult female frog lays eggsThe adult male frog fertilizes the eggsThe frog life cycle starts all over!
