Damage caused by leatherjackets:

1. Root damage: Leatherjackets feed on the roots of grass and other plants. This weakens or kills the grass, resulting in bare patches in lawns or pastures. The root damage can cause the grass to no longer grow properly or to no longer absorb water and nutrients.
2. Bald spots in the grass: Their voracity often causes irregular bald spots in the grass, especially in spring. The grass becomes weak and easily pulled loose by birds or people.
3. Damage to young plants: In vegetable gardens and young crops leatherjackets can cause damage by eating the roots or stems of young plants. This leads to wilting and death of the plants.
