Reported as an adult
No adult season shown here. The weeks are still too uncertain to show a season.
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
Late May to mid-September, middle week Jul 26 – Aug 1
Records per week from 1,518 records in 10 of the 10 years from 2016 to 2025. Shows when people recorded it, not how common it is. The grey bars show how many records of all species were made here each week, so you can see when recording itself was high or low; the season is not adjusted by them.
Recorded on 702 dates. Latest record: October 2025.

Reported as an adult
Usually reported as an adult late May to mid-September, middle week Jul 26 – Aug 1.
From 1,518 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.
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.
