No they are silent. Birds won’t eat them. They stink and taste awful if you ever get one in your mouth riding a motorcycle.
They have no known predators or enemies besides automobiles.
They seem to be attracted by car exhaust.............
I think we have a similar bug here in Texas. Solid black and soft. As children, my brother and I nicknamed them “Charlie bugs” for some reason. Their numbers don’t get out of control, thankfully.
I wonder what their purpose is if they’re not good for food?
I never had a bike without a windshield just because of Hazzards like this...of course that didn’t keep a bee from flying up my shirt sleeve once. 😏
