Kansas University’s Monarch Watch program’s spring open house and plant sale will be from 8 a.m. to 3 p.m. Saturday at Foley Hall on KU’s west campus.

“We’ll have about 4,000 plants, including seven different types of milkweed,” Monarch Watch Director Chip Taylor said.

Exhibits include:

¢ Observation tents with live butterflies, giant moths, hissing cockroaches, tarantulas and caterpillars.

¢ An active beehive.

¢ Presentations on so-called killer bees.

¢ Ant lion cages.

¢ Monarch butterfly videos.

“Bring the kids,” Taylor said. “We’ll have cookies.”

Monarch Watch is a nationally recognized, nonprofit program dedicated to promoting the study and conservation of Monarch butterflies.

Proceeds from the sale will be used to underwrite Monarch Watch research and outreach efforts.
