The topic which is narrow enough is option A. the life cycle of a butterfly.
What is the life cycle of a butterfly?
- Butterflies have 4 life stages.
- Some butterflies also have 4 generational cycles each year.
- The lifecycle of a butterfly includes the egg stage, larva or caterpillar state, pupa or chrysalis stage, and the adult butterfly state.
- Butterflies have several generations; their lifespan will vary based on the generation of the butterfly and the species.
Stage One: Butterfly Eggs
- Butterflies start their life when the eggs are laid.
- Butterflies generally lay eggs on specific plants. These plants provide the right type of food for future caterpillars.
- Butterfly eggs are very small. They are either round, cylindrical, or oval. They can also have ribbing around them. They can be as small as bits of dust and are easily missed by most people. The shape, color, and type of butterfly will determine what the eggs look like.
- Butterflies lay eggs close together. A female adult butterfly will lay many eggs at once so that at least some of them will survive. They also lay their eggs on the underside of the leaf. This helps to protect the eggs from predators.
- Many butterfly eggs rest for about 5 days before they hatch. Monarch eggs will hatch in northern climates as early as March or April. Other species will not hatch until the weather gets warmer.
Stage Two: Caterpillar Larvae
- When the egg hatches, tiny caterpillar larvae emerge. They are very little but have very large appetites. The larvae will immediately start eating and eating. Caterpillars will grow as much as 100 times their original size! They eat many times their weight in food.
Stage 3: Pupa or Chrysalis
- When a caterpillar has eaten enough food to grow to its ideal length and fatness, it will hang upside down. Caterpillars won’t change into chrysalis on the ground. A caterpillar hanging and shaped like a J is probably about to form into a chrysalis.
- Chrysalis is also called the pupa. It is mostly colored green or brown. It is colored to camouflage the colors around it. It makes the pupa more invisible to animals and helps to keep it safe. It protects it from predators.
- The pupa can stay in its stage for a few weeks to a few months. Some species of butterflies stay in the pupa stage for as long as a couple of years! How long the chrysalis stage lasts can also depend on the time of the year and whether or not the butterfly has to hibernate over the wintertime.
Stage 4: Butterfly
When the transformation of the butterfly is complete, the pupa starts to change in color. It can either darken or become translucent. The butterfly emerges from the chrysalis fully formed. An emerging butterfly only takes a few seconds to fully emerge. Very little of the pupa is left after the butterfly emerges.
The lifestyle of a butterfly
Throughout summer and as fall nears, butterfly eggs can be found on the underside of leaves. It left me wondering about the life cycle of the butterfly.
Hence, option A is the answer.
