O’NEILL, Neb. (AP) — Construction of a wind farm in northern Nebraska is being held up by the spring wakeup of endangered beetles.

The American burying beetles make their winter homes in the soil of Nebraska and five other states. Some construction at the northeast Holt County site must wait until the weather warms sufficiently for the beetles to leave their winter homes and move away from the danger.

Seventy-one out of the 200 turbine foundations have been installed, and work on the 400-megawatt Grande Prairie Wind Farm is expected to be finished by late November.
