Rain has put Stan Herd behind about a week, but the world-famous crop artist from Lawrence will unveil another work at 11 a.m. Monday at Pendleton’s Country Market, 1446 E. 1858 Road.

His newest creation is a replica of the new postage stamp depicting a Southern Dogface butterfly.

“I grew up on a farm, so I’m kind of aware of the pollination of the crops, and it was intriguing to me that some of the species are having some trouble,” he said.

Herd said he wanted to get involved in something that had a national scope, and he liked the idea of using his work as a platform for discussion. It has taken him about a month to create the piece, which includes marigolds, purple petunias, mulch and sand.

At the unveiling will be Chip Taylor, a professor of insect ecology at Kansas University, who will speak about the decreasing amount of wild pollinators. Richard Watkins, spokesman for the U.S. Postal Service and Judy Raney, Lawrence postmaster, will discuss the issuance of a block of four “pollinator” stamps.
