Reported as an adult
Usually reported as an adult late March to early October, middle week Aug 9–15.
From 63 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.

Reported as an adult
Usually reported as an adult mid-March to mid-October, middle week Jul 26 – Aug 1.
From 2,044 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 caterpillar season shown here. Most records come from a single year, so a season is not shown yet.
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.

Sources
Where these results come from
Records from iNaturalist research-grade observations and expert-identified GBIF datasets, CC0, CC BY and CC BY-NC. Sources
Seasons use the published method and its evidence thresholds. Methods
A spreadsheet (CSV) with a link to each record, on iNaturalist or GBIF. Records whose location was hidden by the observer or the source are counted but not linked.
