List of The Venture Bros. episodes

The Lepidopterists is the tenth episode of Season 3 and the overall thirty-sixth episode of The Venture Bros.


The Monarch launches his first attack on his new arch nemesis, the other Dr. Venture. But Jonas has the formidable defenses of Spider-Skull Island on his side, as well as his own Team Venture, and the expert advice of a trio of O.S.I. "butterfly specialists." It will take a loose reading of the Guild handbook, an insertion team of his three best henchmen, and all the diabolical chicanery The Monarch can muster to even the playing field.
