In the pink.

[ILLUSTRATION OMITTED]

Seven hot-pink katydids recently made their debut at the Audubon Insectarium in New Orleans, Louisiana. Katydids are usually green, and not much is known about what causes the hot-pink variety. But Jayme Necaise, the Insectarium's director of animal and visitor programs, says scientists think the bugs' pink color probably results from the expression of a rare gene or set of genes (units of hereditary material). After the museum successfully bred the katydids, the immature nymphs underwent several molts (skin shedding) before being put on display as adults.
