Reported as an adult

Usually reported as an adult mid-June to mid-July, middle week Jun 28 – Jul 4.

From 23 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 16 records here are marked as caterpillars, too few to show a caterpillar season. One needs at least 20 records from 5 different years.

Recording in Ohio · records of all species each week, 1,691,199 in all

Records per week from 243 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 147 dates. Latest record: September 2025.

Reported as an adult

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

From 144 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 Aug 30 – Sep 5.

From 99 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
