Cranefly/Leatherjacket Life Cycle
May June July August Sept. Oct.
Crane fly adults are slender, long-legged flies (that look like giant mosquitos) that emerge in Autumn. Leatherjacket, the larval stage of the Crane Fly feeds on the roots of grass causing yellow patches, thinning and death. A female Crane fly can lay 300 eggs that hatch into leatherjacket larvae and quickly become a serious pest of turf grass. Nematodes are living organisms – natural parasites! They are microscopic worms that occur naturally in the soil. Nematodes hunt down and kill Leatherjacket Larvae (Grubs)! Leatherjackets start feeding in September and again in April.

Leatherjackets or European CraneFlies This pest was first reported in the Whitby, Toronto and Hamilton Mountain area in 1996-1998. The larva of this European crane fly, called leatherjacket is most damaging in turf and pastures grasses, but has shown to damage fruit, vegetable and flower crops.
Life Cycle of European Cranefly / Leatherjacket
• Adult: resemble large mosquitoes (size 1.5cm to 2.5cm) with grayish brown body.
• Larvae: light grey, greenish brown cylindrical grub with tapered ends, 3-4 cm at maturity.
• Pupa: brown, spiny and 3.3cm in length. In a typical year this is what we see One generation per season
• May:-Larvae (fourth instar) found feeding on top of the soil
• Mid June: Larvae stop feeding and move down into the soil (3-5cm)
• Mid August:-pupate in mid to late August. • September-October:-Adults emerge lay 200-300 eggs, live 4 -7 days
Eggs need immediate moisture to survive and hatch 11-15 days later. Once hatched the larva feed throughout fall and warm periods in winter in upper 3cm of soil.
Leatherjackets and Beneficial Nematodes: NIC’S Guardian Specific for Craneflies
• In early spring we had good success with applying the nematodes on the feeding larva. However the rate of application must be doubled.
• Later applications on the non-feeding larva did not gain desired control. Leatherjackets stop feeding around mid-June in Ontario, but remain deep in the soil until they pupate in late summer.
• In Ontario, the adult Cranefly (looks like a giant mosquito) flies, mates and lays eggs in your lawn. When you see them flying usually September, this is the time to apply Guardian. NIC’s Canadian strain of beneficial nematode specific for Cranefly/Leatherjacket control.
Fun Fact: Tipulidae is the largest family of flies (Order Diptera) with 1,517 species in the US and Canada. Most larvae are aquatic or semi-aquatic. There are only four species of tipulids that are considered pests.
