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.

“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.”
