Mud Season -> Black Fly Season

Ok, got a nice email from Adirondack Mountain Club announcing that 'Mud Season' has started and requesting we stay below 3k feet. Happy to comply.

Nice video here about it

My question: Do mud and black fly season often overlap? I understand no one has a weather crystal ball but in general terms it will help with planning our next trip (peak, hike or canoe). Or is there often a sweet spot between the two?

Thank you
