The harlequin ladybird (Harmonia axyridis) owes its 200 color variants to a transcription factor’s control over a single gene, according to a study published August 23 in Current Biology

The researchers used genomic and genetic analyses to determine the role of the transcription factor, called Pannier, in the pigmentation of a ladybird’s elytra, or fore wings. The different pannier alleles dictate protein production in specific regions of the elytra, leading to the various patterns of black and red splotches.
