What does bugs in cornmeal look like?

Have you ever looked at your cornmeal or corn muffin and seen a bunch of little black eyes staring back at you? I have. I’ve thought these black spots were bits of stone from a stone-ground masa harina package or bits of pepper, but my biggest fear has always been that they were bugs.

Yes, they can be bugs. That’s the bad news. There’s a good chance, though, that they aren’t.

There may be black spots in cornmeal and foods made with cornmeal. These are pieces of the pericarp, which is the skin around the kernel of corn, especially where it connects to the cob. The bits of germ in whole-germ cornmeal also look like dark specks. But look carefully at your cornmeal. If the spots move or have legs that you can see, they are insects.

If you think the specks might be bugs, there is a good way to check. Mix a teaspoon of the cornmeal in question into a bowl of water. Bugs, on the other hand, will float. Good cornmeal, including bits of pericarp and germ, will sink into the water and mix with it. You can be sure with the help of a magnifying glass.

Natural specks will not be found in large numbers either. They shouldn’t be the main focus of your meal. But if there are a lot of them, it’s likely that they are bugs. Also, a lot of bugs that can get into cornmeal will make it smell bad.

What Do Bugs in Cornmeal Look Like

Dark spots in cornmeal may be psocids, which are also called woodlice or booklice, or any of several types of grain-eating beetles. They can be told apart by their sizes and colors. Psocids can be dark brown or gray and are about the size of a pinhead (1-2 mm), while adult flour beetles are usually reddish brown and about 4 mm long.

The most common types of flour beetles, the red flour beetle and the confused flour beetle, give the grain they eat a strong, almost medicinal smell. Also, flour beetle infestations usually include both adult beetles and their grubs, which look like pale, off-white worms that are about 7 mm long.

Psocids can get into your pantry through wet cartons and paper packaging, which may literally lure them out of the woodwork. Even though they are called booklice or flour lice, psocids aren’t parasites and aren’t related to the louse family.
