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

Records per week from 2,572 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 878 dates. Latest record: October 2025.

Reported as an adult

Usually reported as an adult early May to early September, middle week Jul 26 – Aug 1.

From 2,224 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 mid-June to early October, middle week Aug 16–22.

From 309 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.
