Jerusalem crickets and Mormon crickets are often confused, sharing a similar appearance and eliciting similar reactions (mostly revulsion!). While both are large, flightless insects, belonging to the same order (Orthoptera), they have distinct differences. This article will delve into the details, separating myth from fact and clarifying their unique characteristics.

What's in a Name? Understanding the Confusion

The "Jerusalem cricket" (family Stenopelmatidae) and the "Mormon cricket" (a species of katydid, Anabrus simplex) aren't closely related despite their shared moniker of "potato bug." Their similar appearances – large, dark bodies and powerful mandibles – lead to frequent misidentification. However, examining their biology reveals key distinctions.

Distinguishing Features: Jerusalem Cricket vs. Mormon Cricket

Feature	Jerusalem Cricket (Stenopelmatidae)	Mormon Cricket (Anabrus simplex)
Size	Generally larger, up to 2 inches	Slightly smaller, up to 2 inches
Head Shape	Rounder head	More elongated head
Color	Usually dark brown or reddish-brown	Dark brown to black, sometimes with lighter markings
Mandibles	Powerful, used for digging and feeding	Powerful, used for feeding and defense
Antennae	Relatively short	Long, threadlike antennae
Habitat	Primarily underground	Above ground, often in large swarms
Diet	Omnivorous (roots, insects, etc.)	Primarily vegetarian (grasses, crops)
Scientific Classification	Family Stenopelmatidae	Species Anabrus simplex, family Tettigoniidae (katydids)

Jerusalem Crickets: Masters of the Underground

Jerusalem crickets, also known as potato bugs, are mostly subterranean creatures. They spend much of their lives underground, digging burrows and foraging for food. Their large, powerful mandibles are perfectly adapted for this lifestyle, enabling them to dig through soil and consume a variety of food sources. Their diet is opportunistic, including roots, other insects, and decaying organic matter.

Jerusalem Cricket Myths and Folklore

Many myths surround the Jerusalem cricket. Some cultures believe they are poisonous or venomous, which is untrue. They lack stingers or venom glands. Their intimidating appearance is purely for defense and deterring predators.

Mormon Crickets: A Plague of Biblical Proportions

Mormon crickets, in contrast, are notorious for their swarming behavior. These insects can amass in massive numbers, forming devastating plagues that decimate crops and vegetation. Their voracious appetites and sheer abundance make them a significant agricultural pest. The name "Mormon cricket" originated from their devastating impact on early Mormon settlers in Utah.

Mormon Cricket Control Measures

Controlling Mormon cricket outbreaks requires a multifaceted approach. This can involve biological control (introducing natural predators), chemical control (insecticides), and cultural practices (crop rotation, habitat modification). Large-scale infestations require coordinated efforts to mitigate their destructive impact.

Frequently Asked Questions (FAQs)

Q: Are Jerusalem crickets and Mormon crickets poisonous?

A: No, neither insect is poisonous or venomous. Their intimidating appearance is a defense mechanism.

Q: What is the best way to get rid of Jerusalem/Mormon crickets?

A: For Jerusalem crickets, preventative measures like sealing cracks and crevices in your home are effective. For Mormon crickets, professional pest control is often necessary for large infestations.

Q: What do Jerusalem crickets and Mormon crickets eat?

A: Jerusalem crickets are omnivores, consuming roots, other insects, and decaying matter. Mormon crickets are primarily herbivores, feeding on grasses and crops.

Conclusion: Separating Fact from Fiction

While often confused, Jerusalem crickets and Mormon crickets are distinct insects with different lifestyles and ecological roles. Understanding their unique characteristics helps dispel common myths and appreciate the diverse world of insects. Both play a role in their respective ecosystems, though Mormon crickets can present a significant agricultural challenge. Knowing the differences between these "potato bugs" allows for a more informed and nuanced understanding of these fascinating creatures.
