For the past few months this large larval insect has been causing damage in annual ryegrass, clover, and perennial ryegrass.
Craneflys have a "spoiler" looking tail.
The head of a Cranefly can be retracted as show in this picture.
The European cranefly over winters as a larva feeding on shoots and crowns, but also feeds on roots as well. In the late spring the larger larva come to the surface at night and will feed on above ground parts of the plants. The larva typically will remain active until June, July or August. At that time they pupate and remain dormant in the soil until August-September. In late summer the adults emerge from the soil and mate, starting the cycle over again. Note: A second type of cranefly has a two generation per year life cycle with adult flights in spring and fall.
If you have a low wet area of a field that just does not seem to be looking right or you think that you might have cranflys contact your CPS field man for more information on your options.
