Not playing scientists; ‘We’re being scientists’

Students do their part to help save monarch butterflies

CeCi Whitmer arranged a handful of plastic bags and jelly jars on a tabletop.

“Some of these are a little frosty,” warned the seventh-grader. The containers were fresh from the freezer, and each held the remains of a caterpillar or chrysalide (cocoon), and in some cases, evidence of what had done them in.

Ceci’s, which she had named J-orge after her brother “because they both kind of wander off,” had succumbed after being “infected by something,” she said.

Finding out the something is the task for those in Lea Sevigny’s Natural Expressions class. They’re not playing scientists; “We’re being scientists,” CeCi said.

Since the second day of school, Sevigny’s students at Eastern and Central middle schools have been bringing caterpillars and monarch chrysalides indoors from their native plant garden outside, in order to boost their chances of surviving the transformation from caterpillar to monarch butterfly.

They’ve tagged — using super-sticky eraserhead-sized labels and an extremely light touch — and released more than 30 butterflies so far, and will send their the data to MonarchWatch.org.

Sevigny said she’s read that just 10 percent of monarch caterpillars in the wild make it to the butterfly stage, whereas up to 95 percent of those reared indoors live to adulthood.

“They are very close to being added to the list of endangered species,” she said.

Learning About Threats

There are native plant gardens at both middle schools and at Collins Elementary aimed at attracting species such as monarchs. At Eastern, for example, students experienced the challenge firsthand: There were many dead caterpillars and chrysalides outdoors, Sevigny said, and a number that were alive when brought inside have not survived.

Students researched and determined the specimens died primarily from becoming infected by tachinid flies and chalcid wasps that lay their eggs inside the chrysalides; ophryocystis elektroscirrha parasites, transmitted when monarchs scatter spores on milkweed leaves; and viral or bacterial diseases.

Seventh-grader Zoe Freeman explained that monarch butterflies “are caterpillars and you hum to them, they bob their heads.”

This is the first year Sevigny has done the project with students. She said Natural Expressions students have been engaged at a deeper level than normal and consequently, have been able to easily communicate what they’ve noticed and learned so far this semester.

What’s more, Sevigny pointed out that students have seen the reality of the statistics play out.

“(They) noticed firsthand how important it is for humans to play a part in helping the monarch population succeed. They now understand the importance of human intervention to rear monarchs indoors, to tag the butterflies through a citizen science project, and to plant milkweed.

“They now know they can make a significant difference with this approach.”
