Lesson 6: The Beetle

Performer: LibriVox - Claire Schreuder


'The Beetle Who Did Not Like Caterpillars' from Among the Meadow People by Clara Dillingham Pierson

One morning early in June, a fat and shining May Beetle lay on his back among the grasses, kicking his six legs in the air, and wriggling around while he tried to catch hold of a grass-blade by which to pull himself up. Now, Beetles do not like to lie on their backs in the sunshine, and this one was hot and tired from his long struggle. Beside that, he was very cross because he was late in getting his breakfast, so when he did at last get right side up, and saw a brown and black Caterpillar watching him, he grew very ill-mannered, and said some things of which he should have been ashamed.

"Oh, yes," he said, "you are quick enough to laugh when you think somebody else is in a fix. I often lie on my back and kick, just for fun." (Which was not true, but when Beetles are cross they are not always truthful.)

"Excuse me," said the Caterpillar, "I did not mean to hurt your feelings. If I smiled, it was because I remembered being in the same plight myself yesterday, and what a time I had smoothing my fur afterwards. Now, you won't have to smooth your fur, will you?" she asked pleasantly.

"No, I'm thankful to say I haven't any fur to smooth," snapped the Beetle. "I am not one of the crawling, furry kind. My family wear dark brown, glossy coats, and we always look trim and clean. When we want to hurry, we fly; and when tired of flying, we walk or run. We have two kinds of wings. We have a pair of dainty, soft ones, that carry us through the air, and then we have a pair of stiff ones to cover over the soft wings when we come down to the earth again. We are the finest family in the meadow."

"I have often heard of you," said the Caterpillar, "and am very glad to become acquainted."

"Well," answered the Beetle, "I am willing to speak to you, of course, but we can never be at all friendly. A May Beetle, indeed, in company with a Caterpillar! I choose my friends among the Moths, Butterflies, and Dragonflies,—in fact, I move in the upper circles."

"Upper circles, indeed!" said a croaking voice beside him, which made the Beetle jump, "I have hopped over your head for two or three years, when you were nothing but a fat, white worm. You'd better not put on airs. The fine family of May Beetles were all worms once, and they had to live in the earth and eat roots, while the Caterpillars were in the sunshine over their heads, dining on tender green leaves and flower buds."

The May Beetle began to look very uncomfortable, and squirmed as though he wanted to get away, but the Tree Frog, for it was the Tree Frog, went on: "As for your not liking Caterpillars, they don't stay Caterpillars. Your new acquaintance up there will come out with wings one of these days, and you will be glad enough to know him." And the Tree Frog hopped away.

The May Beetle scraped his head with his right front leg, and then said to the Caterpillar, who was nibbling away at the milkweed: "You know, I wasn't really in earnest about our not being friends. I shall be very glad to know you, and all your family."

"Thank you," answered the Caterpillar, "thank you very much, but I have been thinking it over myself, and I feel that I really could not be friendly with a May Beetle. Of course, I don't mind speaking to you once in awhile, when I am eating, and getting ready to spin my cocoon. After that it will be different. You see, then I shall belong to one of the finest families in the meadow, the Milkweed Butterflies. We shall eat nothing but honey, and dress in soft orange and black velvet. We shall not blunder and bump around when we fly. We shall enjoy visiting with the Dragonflies and Moths. I shall not forget you altogether, I dare say, but I shall feel it my duty to move in the upper circles, where I belong. Good morning."

Directions

Study the lesson for one week.

Over the week:

  • Read the story.
  • Review the animal synopsis.
  • Study the vocabulary words.
  • Learn the concepts.
  • Complete the enrichment activities.
  • Study the review questions.

Synopsis

Like fireflies, butterflies, bees, mosquitoes, and dragonflies, beetles are insects. One notable type of beetle is the ladybug, (also called lady beetle or ladybird) often known for its bright wing covers and black spots. Ladybugs come in many colors, some are red with black spots, some are black with red spots, others are yellow with black spots, and still others are orange with no spots. There are around 5000 species of ladybugs, and different species of ladybugs have different numbers of spots. Contrary to what some believe, the number of spots on a ladybug does not correspond to age and does not change over time. Ladybugs do not taste good to birds and other predators. Both the bright colors and the spots of ladybugs warn birds of their bad taste. Tucked under the wing covers are a pair of wings, a thorax, an abdomen, and three pairs of short legs. Like other insects, ladybugs use antennae to sense their surroundings. Ladybugs help gardeners and farmers by eating crop pests such as aphids. Ladybugs have the same life cycle stages as butterflies. They start as tiny yellow eggs, hatch into larvae, and grow into pupae. Ladybugs remain dormant as pupae for a couple of days before adult ladybugs emerge from their pupae skins. Ladybugs are often associated with good luck.

Vocabulary

Aphid: A minute bug that feeds by sucking sap from plants. They can live in large colonies that cause extensive damage to crops.
Larva: The active immature form of an insect, especially one that differs greatly from the adult and forms the stage between egg and pupa.
Pupa: An insect in its inactive immature form between larva and adult.
Dormant: Having normal physical functions suspended or slowed down for a period of time; in or as if in a deep sleep.
Species: A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.

Concepts

Ladybugs undergo the process of metamorphosis like butterflies.

Facts about ladybug metamorphosis:

  1. Mother ladybugs lay a cluster of tiny yellow eggs, often on a leaf.
  2. Ladybugs hatch into larvae, which eat aphids and other insect pests.
  3. Ladybug larvae grow into pupae, attaching to leaves and remaining dormant for a couple of days.
  4. Ladybugs split their pupa skins to emerge as their adult forms. Find in the below image the discarded pupa skin as well as the new adult ladybug.

Enrichment

Activity 1: Narrate the Story

  • After reading or listening to the story, narrate the story events aloud using your own words.

Activity 2: Watch the Video

  • Study the ladybug in the video. Note the shiny, bright wing covers and the spots of the ladybug. Find the tiny aphids that provide an abundance of ladybug food.

Activity 3: Classify the Animal

  • Ladybugs are animals, invertebrates, arthropods, and insects.
  • Trace which categories ladybugs fit into on the classification chart.

Activity 4: Recite and Memorize a Nursery Rhyme About Ladybugs

Ladybird, Ladybird, fly away home!

Your house is on fire and your children are gone,

All except one,

And her name is Ann,

And she hid under the baking pan.

Activity 5: Color and Label a Ladybug   

  • Click the crayon above. Complete page 15 of 'Science Field Book for Second Grade.'

Activity 6: Take a Nature Walk

Take a nature walk, locate a beetle or other animal to observe, gather data and notes, and use that information to create a field book entry. You may wish to take a pencil and a small notebook to jot down sketches and observations. If you can't find a beetle, you may sketch a different animal or make a sketch based on the video in Activity 2.

Before you take the nature walk, review:

  • The field book template you'll later complete on page 16 of 'Science Field Book for Second Grade.'
  • The suggested list of observations below.

Behavioral observations include:

  • How does the beetle move?
  • How does the beetle eat?
  • What does the beetle eat?
  • How does the beetle sense the world?

Habitat observations include:

  • Does the beetle live in a forest, a field, a town, or near water?
  • In what type of climate does the beetle live (e.g. temperate, tropical, arid, arctic)?

Appearance observations include:

  • What colors are the eyes and body?
  • How many legs does the beetle have?
  • How many antennae does the beetle have?

Activity 7: Complete a Field Book Entry   

  • Click the crayon above. After your nature walk, complete page 16 of 'Science Field Book for Second Grade.'
