Hot pink morph of adult katydid in Panama (Figure 1 photo by Zeke W. Rowe from Ecology: Pink Cricket Club: Dramatic color change in a Neotropical leaf-masquerading katydid (Arota festae, Griffini, 1896))

Katydids are usually hard to find because their green color and leafy shape provide camouflage in their natural habitat. This one in Costa Rica can only be seen because his leaf is lit from below.

When scientists in Panama occasionally found a hot pink version of a normally green katydid (Arota festea) they assumed it was a mutant. Out of curiosity they kept a pink one in captivity and were amazed to discover that it slowly changed color. Within two weeks it turned green.

At every stage, from hot pink to vibrant green, its color camouflaged it among the leaves.

In the [insect] animals’ native jungle home of Suriname, Colombia, and Panama, about 36% of plants turn pink before adopting their typical mature green—a process of delayed greening sometimes called “red flushing.”

This photo from the study, Pink Cricket Club: Dramatic color change in a Neotropical leaf-masquerading katydid (Arota festae, Griffini, 1896), shows the match-up.

The katydid’s color is connected to everything else. Now we know the connection.
