Why Do Mormon Crickets Migrate?

Mormon crickets, a type of shield-back katydid, have been migrating through areas of the West, creating a scene of infestation due to their increasing populations since the late 1990s. These flightless insects, also known as katydids, feed on native plants and have been invading swaths of northern Nevada for weeks. The Mormon cricket takes its common name from the prominent role it played in the miracle of the gulls, after the Mormon settlers in Utah had encountered them while pushing westward.

Drought encourages Mormon cricket outbreaks, which may last several years and cause substantial economic losses to rangeland, cropland, and home gardens. Adult Mormon crickets are large insects, while males move forward in search of food and possibly to avoid being eaten by the crickets behind them. Researchers report hunger for protein and salt, and a fear of cannibalism, driving the mass migration of Mormon crickets in western North America.

Mormon crickets travel long distances by walking, feeding as they go, and do not usually occupy any given rangeland site for more than 3-4 days. As they grow, they go through a series of molts, during which they tend to form bands and move regionally up to a mile per day. In summary, Mormon crickets are walking packages of protein and salt, constituting an abundant potential source of these vital nutrients for hungry individuals. They migrate in search of sources of protein and salts, and when swarming, they must continually keep moving forward to avoid being eaten by hungry crickets.

How Long Do Mormon Crickets Stay At A Site?

Mormon crickets exhibit migratory behavior, typically staying at one site for only three to four days. As flightless insects, they navigate by crawling and hopping during favorable conditions, primarily moving in daylight when temperatures range from 65°F to 95°F. These insects are notable for their large swarms and extensive migrations, forming bands that can travel significant distances. Male Mormon crickets produce a distinctive chirping sound, similar to true crickets, and they can grow to nearly 8 cm (3 inches) in length. Their coloration varies widely, including black, brown, red, purple, or green, and their bodies may exhibit striping patterns.

Mormon crickets have a long ovipositor, similar in appearance to a stinger, and during their swarming phase, they can cover up to two kilometers per day, potentially becoming serious agricultural pests or traffic hazards. These bands feed as they travel, not remaining on a rangeland site for long, which makes it difficult to quantitatively measure their impact.

Nymphs develop through seven instars, maturing by early summer, about 60 days post-hatching. They primarily hatch in undisturbed sites such as pastures or empty lots, migrating to new areas when food sources become scarce. The serious damage they inflict on crops can significantly impact cultivated fields within a few days.

Management strategies for controlling Mormon crickets include erecting barriers, like cricket fences that are 18 to 24 inches tall with a slick plastic covering to prevent them from advancing. Outbreaks of Mormon crickets can last from five to 10 years, with fluctuating populations depending on environmental conditions. Overall, the migratory nature of Mormon crickets plays a crucial role in their life cycle and impact on agriculture.

Do Mormon Crickets Eat Each Other?

Mormon crickets often exist solitarily or in small groups, but can form large migratory bands of millions, leading to population explosions and infestations. These groups, prevalent in western North America, face a scarcity of vital nutritional resources like protein and salt. Cannibalism becomes a survival strategy, as many crickets consume each other to meet their nutritional needs. While they devastate vegetation along their migratory paths, these crickets also feed on injured or deceased individuals, whether from predation, accidents, or insecticides.

The combination of hunger for protein and salt drives their coordinated movement, as the natural inclination for cannibalism emerges when resources are limited, underscoring their opportunistic feeding behavior.

How Do Mormon Crickets Migrate?

Mormon crickets, scientifically known as Anabrus simplex, typically live as solitary insects or in small groups but can band together, resulting in population explosions that may reach 100 individuals per square meter. These large migratory groups can number in the millions and travel significant distances, up to 2 kilometers a day, while destroying vegetation in agricultural areas. Their migration is primarily driven by the hunt for protein and salt, as well as the instinctive need to evade predation from crickets trailing behind.

During their initial life stages, young Mormon crickets are mobile and move individually or in small bands to seek food and shelter. However, as they mature, they often form larger migratory bands, moving together in search of nutrition and safety. Unlike other migratory species, Mormon crickets do not have a fixed destination; they continue to advance towards potential food sources while avoiding cannibalism.

Migration typically occurs during favorable daylight conditions, with temperatures between 65°F and 95°F. Although they can travel at night, daytime is preferred for movement. Typically, these crickets remain at one site for about three or four days before moving on in search of new resources.

While they do not possess wings, their body structure allows them to be highly mobile, and they can traverse vast distances by hopping and crawling. Observations have shown that these swarming insects, during outbreaks, can create long chains that stretch for miles. Resident farmers and communities in the Great Basin region have historically dealt with the impact of these pests owing to the challenges they pose to vegetation and agriculture.

Research identifies the dual factors of hunger for essential nutrients and the threat of cannibalism as primary motivators behind the congregational movement of Mormon crickets in Western North America.

What Does The Bible Say About Crickets?

In the Bible, specifically in Leviticus 11:20-22, there are dietary guidelines regarding insects. Winged insects that walk on the ground are generally considered detestable, with the exception of certain types that have jointed legs suitable for jumping. The permissible insects include various kinds of locusts, bald locusts, crickets, and grasshoppers. This text defines crickets as acceptable food sources, highlighting their inclusion among other clean insects.

The symbolism associated with crickets in the Bible is rich and multifaceted. Their nocturnal song is likened to the whispers of the faithful, symbolizing quiet devotion and reverence. Crickets can represent humility, as their small size and unassuming nature contrast with more prominent creatures. This is noted in Matthew 18:4, where Jesus emphasizes the value of humility. Additionally, crickets serve as reminders of God’s provision, acting as messengers in spiritual contexts. Their presence often signifies a new spiritual journey or exceptional abilities.

Crickets have two main scriptural interpretations: as symbols of insignificance, as seen in the Book of Amos, and as messengers from God, reflecting human qualities of vulnerability and the potential for spiritual awakening. Overall, the Bible portrays these insects as an intricate part of divine messages, guiding believers toward humility and faithfulness, while also providing clarity on dietary laws concerning clean and unclean animals.
