Reported as an adult
Usually reported as an adult mid-July to early November, middle week Sep 20–26.
From 73 records that are marked as adults. Not every photo is marked with a life stage, so this shows when people reported it as an adult, not when adults are about.
Reported as a larva
No records here are marked as larvae yet, so there is no larva season to show. One needs at least 20 records from 5 different years.
In Ohio
Late May to early August, middle week mid-July, and again late August to early November, middle week late September
Recorded in two separate seasons, each shown with its own early, middle and late weeks.
Records per week from 1,298 records in 10 of the 10 years from 2016 to 2025. Shows when people recorded it, not a season or how common it is.

Reported as an adult
Usually reported as an adult late July to early November, middle week Sep 20–26.
From 862 records that are marked as adults. Not every photo is marked with a life stage, so this shows when people reported it as an adult, not when adults are about.
Reported as a larva
No records here are marked as larvae yet, so there is no larva season to show. One needs at least 20 records from 5 different years.
What these results show
These results show when people recorded a species, not when or where it occurs. Missing weeks and low counts do not mean absence or scarcity, and counts are not abundance. Contributed records reflect where, when and what people chose to observe.
