Cyme laeta is a moth of the subfamily Arctiinae first described in 2021 by the then 18-year-old Noortje Looijenga during her internship at the Naturalis Biodiversity Center in the Netherlands.

[2] Laeta is Latin for happy, surprise, colorful and rich in contrast.

Looijenga explained that: "Of course, this refers to my joy upon discovering this new species.

"[3] The type specimen had been caught by Rob de Vos, her internship supervisor, during a work trip.

[1] The determination that this was a different species was made by Looijenga by examining the sex organs under a microscope.
