Reported as an adult

Usually reported as an adult late June to late July, middle week Jul 12–18.

From 107 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 early August to late September, middle week Sep 6–12.

From 305 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.

Identification

How to identify it

Telling it apart

From what Ohio’s records show. Only what the records support is shown.

Often confused with

From iNaturalist’s similar-species counts, refreshed monthly: confusions in Ohio first, then worldwide. Only species with an Ohio result are listed.

When each is reported

  • All recordsNo season shown · 412 records
  • Reported as maleUsually late June to late July, middle week mid-July · 37 records
  • Reported as femaleUsually late June to mid-July, middle week mid-July · 43 records
  • Reported as an adultUsually late June to late July, middle week mid-July · 107 records
  • Reported as a caterpillarUsually early August to late September, middle week early September · 305 records

Not every photo is marked with a sex or a sign, so these show when people reported each, not when it happens.
