    Large moth flights of Forest tent caterpillars are underway in eastern ND and northern Minnesota.
There have been numerous accounts indicating large numbers of moths attracted to lights around
building at night. These moths will be laying eggs that will result in caterpillars feeding in trees next spring.

    The moths can be recognized by their light brown color with two darker bands on the forewings.
The moths only live a few days but the emergence will last for a couple of weeks.
