Crane Fly Larva (Leatherjacket)

Natural Habitat

Moist soil, lawns, pastures, agricultural fields. They prefer areas with high organic matter and are often found just below the soil surface.

Diet & Feeding

Mainly decaying organic matter, roots of grasses, and other plants. Some species can be predatory on other small invertebrates. They can cause damage to lawns and crops by feeding on roots.

Behavior Patterns

Larvae are largely nocturnal feeders. They spend most of their lives underground, often near the surface, especially after rainfall or during damp conditions. They are legless and have tough, leathery skin, hence the common name 'leatherjacket'. They pupate in the soil.

Risks & Benefits

Potential risks include significant damage to lawns, golf courses, and agricultural crops by feeding on roots, leading to brown patches and weakened plants. They can also attract nuisance predators like birds and badgers seeking to feed on them. Benefits include their role in breaking down organic matter in the soil, contributing to nutrient cycling.
