The egg is a tiny, round, oval, or
cylindrical object, usually with fine ribs and
other microscopic structures. The female
attaches the egg to leaves, stems, or other
objects, usually on or near the intended
The caterpillar (or larva) is the long, worm-like
stage of the butterfly or moth. It often has an
interesting pattern of stripes or patches, and it
may have spine-like hairs. It is the feeding and
growth stage. As it grows, it sheds its skin four
or more times so as to enclose its rapidly growing
The chrysalis (or pupa) is the
transformation stage within which the
caterpillar tissues are broken down and the
adult insect's structures are formed. The
chrysalis of most species is brown or green
and blends into the background. Many
species overwinter in this stage.
The adult (or imago) is colourful
butterfly or moth usually seen. It is the
reproductive and mobile stage for the
species. The adults undergo courtship,
mating, and egg-laying. The adult
butterfly or moth is also the stage that
migrates or colonizes new habitats.
• Life cycle of a frog: web-footed amphibian which lives near lakes and
• ponds. Moves by swimming and jumping.
Adult frog: mature frog.
Tadpole frog: phase of the life cycle of a frog between tadpole and adult.
Start of pulmonary respiration: the beginning of respiration with the lungs.
Front legs break through: beginning of the development of the rear limbs.
Tadpole: frog larva.
Embryo: frog still in the egg.
Eggs: cell resulting from a fertilized ova which contains the frog embryo.

The life cycle of a frog starts when mom and dad frog fall in love and decide to have baby frogs.
Okay, nobody really knows if frogs fall in love, but it’s okay to think that they do. Mom and dad frog
will mate, either in the water or in a tree, depending on what kind of frogs they are.
Mom frog will lay a bunch of eggs for the
dad frog to fertilize. Unlike human eggs, frog
eggs are fertilized by dad frog when they are
outside of the mom frog’s body. This is called
spawning and is the very beginning of the
frog life cycle. After the mom and dad frog
have finished spawning, dad frog leaves, and
sometimes the mom frog does, too.
Sometimes mom frog will stick around,
though, and wait for the baby frogs to hatch
so that she can care for them, but this only
happens with some breeds of frogs, not all of
The Frog Eggs
Mom frog will lay a whole bunch of eggs because
most of them won’t hatch. Some of the eggs will be
eaten by other small animals and birds, and some of
them won’t become fertilized. Other eggs might
become dried up in the sun or get broken in the
water. The eggs that survive will hatch after about 7
to 9 days and begin the frog cycle and start the many
life stages of a frog. But they don’t get to be frogs just
yet; they have to go through the tadpoles’ life cycle
When frog eggs hatch they don’t come out
as frogs right away, they have to start out
as tiny little fish-like creatures called
tadpoles. In the beginning 7 days or so of
tadpole development, a tadpole will eat the
egg yolk that is still left in its gut. The only
parts to the baby tadpole are the gills, the
tail, and the mouth. After about 7 days of
tadpole development, the tadpole will
begin to swim around on its own and eat
algae from the top of the water.
About four weeks into the tadpoles life cycle it will
begin to grow teeth and skin over the gills and will
begin to become social and swim in schools like fish.
Then 6 to 9 weeks into the tadpoles development it will
begin to grow longer and develop a little bit of a head
and some legs. At the end of the 9 weeks, the tadpole
will look more like a frog than a fish, but with a long
tail. The tadpole will also start to eat things like tiny
In areas of the world that have cold winter months or
that are in very high altitudes, which also are
sometimes very cold places, the tadpoles life cycle
takes all winter long to complete.
From 9 to about 12 weeks, the frog
metamorphosis starts to really take
shape. The tadpole that looks like an
itty bitty frog but with a long tail (called
a Froglet) will lose most of its tail, grow
a frog tongue, and start to really look
like a baby frog. The whole frog life
cycle model is completed after about
16 weeks when the frog becomes an
