NEW ORLEANS (AP) — As the nation prepares for trillions of red-eyed bugs known as periodical cicadas to emerge, it’s worth noting that they’re not just annoying, noisy pests — if prepared properly, they can also be tasty to eat.

Blocks away from such French Quarter fine-dining stalwarts as Antoine’s and Brennan’s, the Audubon Insectarium in New Orleans has long served up an array of alternative, insect-based treats at its “Bug Appetit” cafe overlooking the Mississippi River. “Cinnamon Bug Crunch,” chili-fried waxworms, and crispy, cajun-spiced crickets are among the menu items.

Periodical cicadas stay buried for years, until they surface and take over a landscape. Depending on the variety, the emergence happens every 13 or 17 years. This year two groups are expected to emerge soon, averaging around 1 million per acre over hundreds of millions of acres across parts of 16 states in the Midwest and South.
