Dead Flies? clinging to Blueberry Bushes #755314

Good afternoon. We have noticed a large number of what appear to be some type of fly clinging to our blueberry bushes. Nearly all are dead and many seem to be clinging to dead stems leading me to wonder if they were the cause of the stem's death. We are just North of Williamston, MI outside of East Lansing.
Ingham County Michigan
Expert Response
These flies have been infected and killed by a fungal disease called Entomophthora muscae. This disease only affects certain types of flies and poses no danger to your plants or to you.
