Reported as an adult
Usually reported as an adult mid-June to early August, middle week Jul 5–11.
From 64 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 caterpillar
No records here are marked as caterpillars yet, so there is no caterpillar season to show. One needs at least 20 records from 5 different years.
In Ohio

Reported as an adult
Usually reported as an adult mid-June to late July, middle week Jul 5–11.
From 795 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 caterpillar
Only 1 records here are marked as caterpillars, too few to show a caterpillar season. 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.
