Scientist Nathan Morehouse has discovered that one of the most common butterflies — the white cabbage — has an unusual sex life, including large, protein-rich ejaculates that nourish the females as they produce offspring, according to the Atlantic.

How it works: Male butterflies ejaculate a solid package (unlike humans) of sperm called a spermatophore, which is often 13% of its body weight. The package is left in a pouch in the female's reproductive tract where the sperm moves on to a second pouch where it will later fertilize eggs. The rest of the protein-packed spermatophore is broken down for the female's nourishment. One spermatophore provides females with the nutrients needed for almost half of the eggs they'll lay.

While the white cabbage butterflies look common and plain to humans, their wings reflect the sun's UV rays, which give the females a lavender color and males a glowing purple color. The brighter the purple of a male, the more attractive it is to a female as it is a reflection of the butterfly's fitness and the nourishment the female might receive.

Clock's ticking: Scientists think male butterflies have sex 2-3 times in their life. Females, who have leftover spermatophore shells that can be counted, typically mate 2-3 times, but as many as 6 times in a lifespan.

Anthony Fauci told The Atlantic on Wednesday that efforts by certain White House officials to discredit him are "bizarre" and that it "ultimately hurts the president" to undermine a top health official in the middle of a pandemic.

Driving the news: Fauci's comments come on the heels of a USA Today op-ed by White House trade adviser Peter Navarro, who claimed that Fauci has been "wrong about everything" related to the coronavirus that the two have interacted on. Fauci told The Atlantic: “I can’t explain Peter Navarro. He’s in a world by himself.”

Oklahoma Gov. Kevin Stitt (R) announced on Wednesday he has tested positive for the coronavirus and will self-isolate, Tulsa World reports.

Why it matters: The 47-year-old Stitt is believed to be the first governor in the U.S. to test positive. He attended President Trump's rally in Tulsa last month, which the county's health department director said likely contributed to a surge in cases in the region.
