Though most katydids are green, once in a while someone discovers a pink one. And indeed while hiking at Middlefork Savanna near Lake Forest recently, Allison Frederick found a pink katydid. Frederick, an environment communications specialist for the Lake County Forest Preserves, discovered the pink insect during a phenology and photography workshop.
First described in 1887, “the pink katydid is so rare that they occur once out of every 500 individuals,” Frederick said. This coloration is the result of a condition called erythrism, similar to the recessive gene found in albino animals, she said.
