June is the month in Michigan for fly fishing after dark, with big bugs for big trout. The month’s hatches start with the brown drake mayfly, followed by the isonychia mayfly, and rounded out by Michigan’s biggest mayfly, the hexagenia. Each bug can be expected to hatch in one to two weeks on a given water body, with some overlap. With the warm weather so far in 2012, the hatch schedule has been accelerated in Michigan so the hatches this year may be more intense and last fewer nights that usual.
Bugs will begin to emerge in the evening after sunset and can continue well after dark. Roughly 48 hours later those same bugs will return to the water they hatched from and die. Both events cause a feeding frenzy in the fish community and provide a lot of fun for the anglers that take advantage of the feeding fish. Contacting a local fly shop or bait shop is a good place to look for information on hatch activity on a specific water body.
