Yo Wants to Know

Yo and Grandpa stand in a field with a book on butterflies.

“Let's look for monarch butterflies,” says Grandpa.

“OK,” says Yo. “What color are they?”

“Black and orange,” says Grandpa.

Grandpa is pointing to the sky with Yo looking up to him

“It may be too late in the season for them. Last night was chilly. Hey, Yo, what's so funny?”

“Nothing,” says Yo.

“Monarchs can't stand cold,” says Grandpa. “When it cools off around here, they go to a warm place, like Mexico.”

“That's far away, right?” asks Yo.

“Yes, but they're strong fliers,” says Grandpa. “They rest in trees at night.

“They stop to sip nectar from flowers and water from streams and puddles.

“After weeks of flying, they reach their winter home.”

“We'll watch for monarchs next summer,” says Grandpa. “There will be lots of them around here then.”

“I think you should check out your hat, ” says Yo.

“Ha!” says Grandpa. “Now I know what was so funny.”

  1. Look at the illustrations. Think about where the monarch butterflies will go next. What season is it now?
    How do you know?
    [anno: Students may answer that it is either summer or fall. Students may think it is summer because many of the plants are still green. They may think it is fall because the butterflies fly to Mexico in the winter, and the grandfather mentions that it is cooling off.]
  2. Why do the monarch butterflies fly to Mexico?
    Name two reasons.
    [anno: The monarch butterflies fly to Mexico because it is warmer there in the winter. There is more food in Mexico during the winter.]
  3. What might happen if the butterflies did not fly to Mexico?
    [anno: The monarch butterflies might freeze during the winter.]
