Butterfly Life Cycle 1st Grade Test

The chrysalis is the pupal stage of a butterfly's life cycle. During this stage, the caterpillar undergoes metamorphosis and transforms into a butterfly. Therefore, the correct answer is butterfly.

The life cycle of a butterfly involves a series of distinct stages, starting from an egg, then progressing to a larva (caterpillar), followed by a pupa (chrysalis), and finally emerging as a fully formed adult butterfly. This transformation from one stage to another is known as metamorphosis. Therefore, the correct answer is "a metamorphosis."

A butterfly begins its life as an egg. The egg is laid by the adult female butterfly on a suitable host plant. Inside the egg, a tiny caterpillar or larva develops. After a period of time, the larva hatches from the egg and starts its journey of transformation, eventually forming a chrysalis and emerging as a fully grown butterfly.

The monarch butterfly undergoes a complete metamorphosis, which consists of four distinct stages in its life cycle. These stages include the egg, larva (caterpillar), pupa (chrysalis), and adult butterfly. Each stage serves a specific purpose in the development and transformation of the butterfly, from the hatching of the egg to the emergence of the adult butterfly. Therefore, the correct answer is 4.

The Monarch Butterfly is orange and black to warn predators to stay away. This coloration serves as a defense mechanism called aposematism, where bright colors act as a warning signal to potential predators that the butterfly is toxic or unpalatable. By displaying these striking colors, the Monarch Butterfly is essentially saying "I am dangerous, stay away from me." This helps protect them from being eaten by predators, as the predators learn to associate the bright orange and black coloration with a bad taste or toxicity.

The correct answer is chrysalis. A chrysalis is a protective covering that the larva, also known as a caterpillar, creates around itself. Inside the chrysalis, the caterpillar undergoes a process called metamorphosis, where it transforms into a butterfly. The chrysalis provides a safe environment for the caterpillar to undergo these changes and eventually emerge as a fully formed butterfly.

A caterpillar is commonly referred to as a larva. This is because a caterpillar is the immature stage of a butterfly or moth, and larva is the scientific term used to describe this stage in the insect's life cycle. During this stage, the caterpillar undergoes significant growth and development before eventually transforming into a butterfly or moth.

A monarch egg hatches into a monarch larva. After the egg is laid by the female monarch butterfly, it takes around 4-6 days for the egg to hatch. Once hatched, the larva emerges and starts feeding on milkweed leaves. The larva goes through several stages of growth, shedding its skin each time, until it reaches its final larval stage. At this point, it forms a chrysalis and undergoes metamorphosis, eventually emerging as a fully developed monarch butterfly.

Monarch caterpillars eat milkweed. Milkweed is the primary food source for monarch caterpillars as it contains toxins that make the caterpillars and adult monarch butterflies poisonous to predators. The caterpillars feed on the leaves of the milkweed plant, which provides them with the necessary nutrients and chemicals needed for their growth and survival. Without milkweed, the monarch caterpillars would not be able to develop and transform into butterflies successfully.

Monarch caterpillars only eat milkweed plants to protect themselves. Milkweed contains toxic compounds called cardiac glycosides, which are harmful to most animals. However, monarch caterpillars have evolved the ability to sequester these toxins in their bodies, making them unpalatable and poisonous to potential predators. By exclusively feeding on milkweed, monarch caterpillars are able to protect themselves from being eaten by other animals.
