The Clark and Morehouse Lab research is featured in PNAS and the Atlantic

The group discovered surprising abilities in a seemingly common butterfly, the cabbage whites – their reproductive capabilities are extraordinarily complex and powerful.

Quick highlights about the butterflies from the text:

  • Males create spermatophores that are 13% of their body weight, which he builds inside of the female.
  • Females have reproductive tracts that are more efficiently stomach-like than their own stomachs (including a chewing jaw that helps them break down the nutrients in the spermatophores).
  • Their relationship is a rapidly evolving battle of the sexes.

The article is an interesting read about a seemingly plain jane butterfly. You can read more in the Atlantic: “This Common Butterfly Has an Extraordinary Sex Life” by Ed Yong. The research can be found in PNAS.
