Leatherjacket (European Marsh Crane Fly)

Tipula paludosa, T. oleracea

Leatherjacket larvae are the immature stage of the European Marsh Crane Fly. They are tough-skinned, light-grey or greenishbrown with irregular black specks, 3 to 4 cm (1.2 to 1.6 inches) long and live in the soil throughout the fall and winter.

During the day, Leatherjackets feed on grass roots and crowns in the upper 3 cm (1.2 inches) of soil. They emerge to feed on grass leaves and stems at night. If the upper soil dries, these larger larvae migrate to deeper soil. They feed in spring through to early-summer when they form a pupa, emerging in late-summer or early-fall as adult Crane Flies.

The decision to take control measures is better made in the spring because late-summer drought or a severe winter may sufficiently reduce the Leatherjacket population. A well-maintained turf is able to withstand a mild infestation so control measures may not be justified. Higher numbers (greater than 270 larvae/m2) will likely cause turf damage.

Turf Symptoms

• Patches of dead grass.
• Turf begins to thin and die back.

Control Options

• Improve drainage conditions.
• Avoid irrigating a dry lawn in the fall if you suspect a Leatherjacket infestation.
• Apply an insecticide to the affected area.


APPLY SEVIN T&O PLUS AT THE LARVAL STAGE AT THE RATE OF 200 mL/100 m2
