Remember the tent caterpillar infestation last year at this time? What a mess. The rumor started that the DNR introduced large gray flies to the U.P. (sometimes known as "garbage" flies) to fight the caterpillars. The U.S. Forest Service has stated that the DNR did not release them here, instead they are native to the area.
But it is true that the flies have fought back against the caterpillars. The flies hatch their young on the cocoons (I won't say maggots this early in the morning) and they eat the pupa before it can emerge. Yuk.
So actually we have less moths, and in turn, less new caterpillars.
Our thanks to Donn de Yampert for another National Geographic quality photo. We'll let his gray fly battle Dan Urbanski's tent caterpillar.
