Crane fly larvae chew on the roots and crowns of the turf and larger instars will come up at night to feed on the foliar tissue. Damage is usually more noticeable late fall and in spring when larger, overwintered larvae have resumed feeding. Damage typically starts as a general thinning of the turf which progresses to larger, brown patches. Unless they occur in large numbers, crane flies are.
However, crane fly larvae are voracious feeders. They feed on grass roots, seedlings, flowers, fungi, decomposing wood, algae, etc. Larvae of some crane fly species can be carnivorous, and feed on mosquito larvae, small insects, and invertebrates. So, such larvae can be predators too. Some others are shredders as they use their specialized mouth parts to shred their food. Some are gatherers.
In July, they told me, the year’s crop of crane flies must have laid eggs on the lawn. Their larvae had hatched and burrowed under the turf and begun to eat its roots and destroy them. In turn.

Since almost all crane fly species live near the water and not in the water, it can be very productive to fish crane fly patterns in the days following rain storms or significant bumps in flows. Rain storms and flow increases tend to knock these clumsy critters into the water and into the feeding path of hungry fish. Typically you will find crane flies near the banks where they live and are.
Healthy turfgrass is the best insurance against crane fly larvae, and in the fall they can be naturally controlled somewhat if the grass is allowed to dry out. This results in the desiccation of the eggs. The only other cultural control she has found to be successful is to fertilize and try to get the grass to grow out of the damage. This is usually best accomplished if the problem is.
