Reported as an adult
Usually reported as an adult early June to mid-September, middle week Aug 9–15.
From 318 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 July to mid-October, middle week Aug 9–15.
From 369 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.
Waved SphinxCeratomia undulosaOften confused in Ohio: 17 identifications in Ohio named one where the other was meant

Elm SphinxCeratomia amyntor16 identifications worldwide named one where the other was meant
Hagen's SphinxCeratomia hageni13 identifications worldwide named one where the other was meant
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 recordsUsually late June to early October, middle week early August · 689 records

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.
