Erythrism in katydids has been occasionally observed. The coloring might be a camouflage that helps some members of the species survive on red plants.[4] There is also consensus that the erythristic mutation is actually a dominant trait among katydid species, albeit a disadvantageous one, due to the overwhelmingly green coloration of most foliage. Hence, most pink or otherwise vividly colored katydids do not survive to adulthood, and this observation explains their rarity.[5] Erythrism in leopards is rare, but one study[6] reported that two of twenty-eight leopards seen in camera traps in a South African nature reserve were erythristic, and the authors found records of five other "strawberry" leopards from the region.[7]
