What Do Jerusalem Crickets Eat? A Quick Guide for the Curious

Jerusalem crickets are fascinating insects that are predominantly found in the western United States. These nocturnal creatures prefer living underground and are known for their unique appearance.

When it comes to their diet, Jerusalem crickets are omnivorous. They feed on a variety of items, including insects, nonwoody roots, and tubers. Although they may appear intimidating, these insects are considered harmless to both humans and woody plants. So as you encounter these peculiar crickets in your garden, rest assured that they are simply going about their daily routine of searching for their next meal.

Understanding Jerusalem Crickets

Jerusalem crickets, also known as Niño de la Tierra or Cara de Niño, are insects belonging to the Orthoptera order in the family Stenopelmatidae (Stenopelmatus fuscus) found mainly in the western United States. They are a unique species with a distinct appearance. Here are some key features of Jerusalem crickets:

• Body color: They have a combination of black, brown, and orange bands on their abdomens.
• Size: Their body size ranges from 1 to 2.75 inches long.
• Antennae: These insects have long antennae that help them navigate their surroundings.
• Legs: Jerusalem crickets have powerful hind legs used for digging.

The nickname Stone Cricket can be attributed to their habit of burrowing in soil and seeking refuge under rocks. Their appearance can be quite fascinating, with features like large, round heads and shiny back plates on their abdomens.

However, even with such striking looks, these insects don’t have wings, making them flightless. They make up for the lack of wings with impressive burrowing skills. These abilities make them efficient at finding their primary food sources, which include insects, nonwoody roots, and tubers according to the University of California Agriculture and Natural Resources.

Jerusalem crickets are mostly harmless to humans and woody plants. However, it is crucial to remember that their powerful jaws can deliver a painful bite if they feel threatened. It’s best to observe and appreciate these fascinating insects from a safe distance.
