Why Are Jerusalem Crickets Called Earth Babies?

Jerusalem crickets, also known as potato bugs or earth babies, are fascinating insects that belong to the Stenopelmatidae family. Despite their misleading name, these creatures are not true crickets and are more closely related to grasshoppers and katydids. So, why are they called earth babies?

The name “earth baby” is derived from the Jerusalem cricket’s unique appearance and behavior. These insects are large, robust, and have a round, bulbous head that resembles a human baby’s head. Additionally, they are predominantly found underground, burrowing in soil, hence the association with being “earth babies.”

Here are a few key reasons why Jerusalem crickets acquired this intriguing nickname:

1. Physical Resemblance: The prominent round head and stout body of Jerusalem crickets bear a resemblance to an infant’s head, leading to the “earth baby” moniker.

2. Underground Dwellers: Jerusalem crickets spend the majority of their lives underground, creating burrows in soil or decaying organic matter. This behavior further reinforces their association with the earth.

3. Protective Mothers: Female Jerusalem crickets guard their eggs and young, demonstrating a nurturing behavior similar to that of human parents, which adds to the notion of them being “earth babies.”

4. Maternal Care: Female crickets lay their eggs in burrows and provide parental care until the nymphs hatch. This maternal behavior strengthens the connection between Jerusalem crickets and the concept of babies.

5. Limited Mobility: Jerusalem crickets are not agile fliers or jumpers like true crickets. Their slow movements and preference for crawling on the ground contribute to the perception of them as earthbound creatures.
