Gypsy Moth Tachinid
A parasitic fly introduced to North America from Europe to control gypsy moths. It has an extremely broad host range attacking over 200 insect species.
Did You Know?
Its introduction to North America is now considered a mistake because it devastated native silk moth populations.
Cluster Fly
A medium-sized, dark gray fly with golden-brown hairs on the thorax. In autumn, it gathers in large clusters inside buildings to hibernate, sometimes in the thousands.
Did You Know?
The larvae of this fly are earthworm parasites, burrowing into the worm through its skin and consuming it alive from the inside over several weeks.
