These eggs remain in the gravel throughout the winter, and the embryos develop.
Life Cycle The Life Cycle of a Monarch Butterfly Before a butterfly can flap its wings, it starts out as something completely different and transforms itself through four stages.
First as an egg, then as a caterpillar, next as a pupa in its chrysalis, and finally, it emerges as a butterfly.
This entire process takes about four weeks from start to finish; although the warmer it is, the shorter the cycle. Egg A butterfly begins as an egg, laid on the underside of a milkweed leaf. A female Monarch will lay one egg at a time, up to !
They lay so many because only about one in 20 make it to adulthood.
Caterpillar Inside the egg grows a caterpillar, or larva, and there are five parts to this stage, which are known as Instars. The first bite of milkweed is a dangerous one, because milkweed latex can act like glue. Some caterpillars die from that first meal because their mouths gum up.
If it survives, the caterpillar then takes a break to shed or molt its skin. The caterpillar is bigger and its colours are more vibrant. Its tentacles grow longer.
At this stage, caterpillars can eat a whole leaf in under an hour! It has to hold onto the silk button while slipping the rest of its skin off.
Once this happens, the caterpillar becomes a pupa. Pupa The pupa, or chrysalis, is soft at first but in about an hour, the shell hardens to protect the growing butterfly within. The pupa has no eyes, antennae or legs but inside a complete metamorphosis is going on.
The mouth changes from what the caterpillar needed to chew milkweed leaves into a straw-like tongue that the butterfly will need to sip nectar from flowers. And it grows wings! All in just about two weeks. Butterfly Finally, the shell bursts open and a butterfly emerges.
It takes a couple of hours before it can fly because its wings are tiny, wet and wrinkly. The butterfly pumps body fluid, called hemolymph, into the wings to make them grow big and strong.
The butterfly flies off in search of its first meal, which it will slurp up through its straw-like tongue, or proboscis. It is a somewhat puzzling concept to wrap your mind around, but it takes generations of monarchs to make the journey north from Texas to southern Canada but only 1 generation to make the entire trip south to Mexico.
The northern generations of monarchs only live weeks on average as they follow the milkweed bloom — a plant they lay their eggs on and the only plant that caterpillars will eat.
The generation that makes the longest leg of the migration south to Mexico, where it rests for months, will make the final short leg to Texas to complete the cycle, is known by scientists as the migratory generation. In order to make the long journey they must conserve energy. After their long journey south, they overwinter in Mexico for several months in oyamel evergreen trees set high in a few isolated peaks in the cool Sierra Madre mountain range.
The Milkweed Plant Named for its milky juice, more than varieties of milkweed exist, and most are poisonous to many animals — but not to Monarchs. Female Monarchs normally lay one egg per milkweed leaf. As they grow, caterpillars fill themselves with milkweed poison.
It stays in their orange and black wings, as a reminder to predators that they taste bitter. A perennial that generally blooms between May and August, milkweed plants prefer soil that is rocky, sandy, and clay.Life Cycle The Life Cycle of a Monarch Butterfly.

The Main Sequence: The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium. The main sequence is the current stage of our sun. Our sun is currently fusing hydrogen into helium.
Stage three: Next few billion years Within the next few billion years of the lifespan, our sun will continuously grow larger and brighter until eventually life will cease to exist on earth.

Spring Context is also responsible for injection dependencies in the bean, either through setter or constructor methods or by spring autowiring..
Sometimes we want to initialize resources in the bean classes, for example creating database connections or validating third party services at the time of initialization before any client request.
