Insects that Burrow in the Ground: Uncovering Earth’s Hidden Dwellers

Insects are fascinating creatures that can be found in various habitats, including the soil beneath our feet. Some of these soil-dwelling insects have adapted to burrow through the earth, making it their home and playground.

One example of a burrowing insect is the burrower bug, which mainly stays in the soil unless it’s migrating to a new location. These little bugs, about ¼” in size, resemble small stink bugs and thrive in hot, dry weather conditions. They are known to feed on plants such as peanuts, occasionally causing damage to crops.

Wood-boring insects are another example of burrowers found in trees and shrubs. These insects, usually moth and beetle larvae, tunnel and feed under the bark of living wood. Although the damage is mostly cosmetic and doesn’t usually affect the structure of the wood, these insects can still weaken trees and cause their decline over time.

Types of Burrowing Insects

Ants

There are numerous ant species that burrow in soil, with varying sizes and depth of the tunnels. Some examples include:

• Fire ants
• Carpenter ants
• Leafcutter ants

Their tunnels have different functions, such as:

• Nesting chambers
• Food storage
• Access to other colonies

Bees and Wasps

Several species of bees and wasps construct underground nests. Some examples are:

• Yellowjackets
• Digger bees
• Ground-nesting wasps

They excavate soil to create chambers for egg-laying and larval development.

Cicada and Cicada Killer Wasps

These insects are known for their relationship with soil:

• Cicadas: spend years underground as nymphs, tunneling and feeding on tree roots.
• Cicada killers: solitary wasps that burrow in soil to create nest cells for their larvae.

Termites and Springtails

Two notable examples of soil-dwelling insects are:

• Termites: social insects that build extensive underground tunnel systems.
• Springtails: tiny, wingless insects that burrow in soil for moisture and organic matter.

Burrowing Bugs and Earwigs

These insects exhibit burrowing behavior:

• Burrowing bugs: soil-dwelling insects that feed on plant roots and seeds.
• Earwigs: nocturnal insects that hide in soil crevices during daytime.

Habitat and Environment

Desert Insects

Desert insects are fascinating creatures that thrive in harsh conditions. Some examples include:

• Australian Desert Ants known for their impressive navigation skills
• Jerusalem Crickets that dig burrows and feed on roots found in the deserts of the United States

Both have adapted to the dry, hot climate and utilize burrows to maintain moisture and stay cool.

Winter Burrowing Insects

While numerous insects burrow in the ground, few continue this behavior in winter. However, some insects do endure the cold:

• Snow Fleas which stay active in snow-covered soil
• Grubs sheltering in lawns beneath the frost line, waiting for spring

These insects showcase remarkable adaptability and resilience, making them unique in their environments.

Insects in Trees and Vegetation

Insects can also be found burrowing in trees and vegetation, taking advantage of plant resources. Examples include:

• Bark Beetles tunneling in tree bark for food and shelter
• Emerald Ash Borers posing a threat to trees in the United States

These insects have developed specialized abilities to exploit trees and foliage as habitats.

Role in Pollination

Solitary Bees

Solitary bees, like the sweat bee, play a key role in pollination. These bees:

• Do not live in hives
• Collect nectar and pollen for their offspring
• Often nest in the ground

Examples of solitary bees include mining bees and digger bees.

Ground Bees

Ground bees are a type of solitary bee. They have important characteristics:

• Burrow nests in soil
• Often mistaken for bumble bees
• Efficient pollinators

One example is the mining bee, which helps pollinate various plants.

Mason and Cellophane Bees

Mason and cellophane bees are other types of solitary bees. They differ in nesting habits and materials used. A comparison:

Both types contribute to successful pollination and fruit production.

Interactions with Humans and Agriculture

Impact on Crops and Flowers

Burrowing insects impact both crops and flowers. Some insects cause damage, while others are beneficial. For example, common ground bees, which are often seen in small colonies, help with pollination. Pollination is a critical process that allows plants to reproduce, thereby maintaining healthy ecosystems.

In contrast, burrowing bugs like lice may feed on plant roots, causing significant damage to crops and flowers. Preventing such damage often requires farmers to use targeted chemical treatments and management strategies.

Managing Flying Insects in Lawns

Managing flying insects that burrow, like the plasterer bees, mason bees, or cellophane bees, can be challenging. These insects are attracted to lawns because of abundant prey and nesting opportunities. The following tips can help manage flying insects in lawns:

• Regularly mow and maintain your lawn to reduce nesting spots
• Use screened covers on trash cans
• Keep outdoor seating and play areas clean
• Install insect containment or repellent measures such as bug zappers or citronella candles

On the other hand, remember that many flying insects contribute positively to pollination and natural pest control.

Recognizing Burrowing Bug Damage

Being able to recognize burrowing bug damage is important in order to address the issue accordingly. Here are some common signs of damage:

• Holes or entrance points in the soil
• Yellowing or wilting of plants
• Droppings and debris around entry points
• Excessively wet or poorly drained soil

To make a better understanding, here is a comparison table of burrowing insect examples:

Each burrowing insect has its unique features and impact on humans and agriculture. By learning to identify and manage them effectively, humans and insects can coexist, ensuring a balance between negative impacts and beneficial interactions.

Insect Anatomy and Behavior

The Science of Insect Burrows

Insect burrows are underground tunnels created by some insects for various purposes, like feeding and breeding. For example, soil insects like wireworms, false wireworms, and white grubs burrow through the soil, feeding on the roots of plants such as grass. Their burrowing methods involve:

• Packing soil along the sides of their tunnels.
• Employing a peristaltic movement, like caterpillars with their hydrostatic skeleton.

Insect Relationships and Colonies

Insects that burrow often form colonies, as seen in ants and bees. For example, ant colonies consist of various adult forms like male ants, queen ants, and female ants (workers).

Some insects, like bees, also have crucial relationships with flowers, assisting in the pollination process.

Defensive Mechanisms

Insects have developed diverse defensive mechanisms, such as:

• Excreting harmful substances to deter predators.
• Using their burrows as hiding places to protect themselves from threats.

Ticks, for example, hide in grass and wait for potential hosts on which to feed, posing a risk to both humans and animals. On the other hand, some burrowing insects like bees can benefit ecosystems by pollinating plants, producing honey, and helping green spaces thrive.
