On Wednesday, The Late Show‘s Stephen Colbert compared President Donald Trump to a butterfly except, he noted, butterflies get past their “larval” stage.

It came during talk of how the National Butterfly Center is trying to stop federal officials from building a border wall across their land.

“The actual problem isn’t for the butterflies, of course. It’s for the people who work to preserve them on their southern migratory route, because the wall would cut the 100-acre property in two, with as much as 70% of the land inaccessible,” Colbert explained. “And the people at the butterfly center say they’ve already found government contractors cutting down their trees and mowing down brush that provides critical habitat for butterflies.”

The audience booed loudly.

He then quipped: “It’s like Trump’s people are saying, ‘I know kids in cages sounded evil, so we’ve toned it down: We’re just strangling butterflies!'”

That is when he noted Trump’s butterfly-like qualities.

“I am surprised Trump’s letting them get away with this,” Colbert joked. “After all, he’s got a lot in common with butterflies: They’re both fragile creatures with bright, iridescent coloring, and paper-thin skin. It’s just that Trump has never left the larval stage.”
