May, June and July — those are the months with the most insects recorded from northern lower Michigan, 19 in May, 26 in June and 24 in July. The trout season on Houdek Creek runs Last Saturday in April–September 30th. MDNR classes most of its typed water as cold, and no gauge on it reports temperature, so the calendar below is the hatch record rather than a thermometer.

Insects peaking each month. Midges, scuds and sculpins are left out: they peak every month, so counting them would flatten the bars.
