Reported as an adult
Usually reported as an adult early May to late July, middle week Jul 5–11.
From 688 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
Usually reported as a caterpillar late May to mid-August, middle week Jun 28 – Jul 4.
From 116 records that are marked as caterpillars. Not every photo is marked with a life stage, so this shows when people reported it as a caterpillar, not when caterpillars are about.
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.
