Reported as an adult
Usually reported as an adult late June to late August, middle week Jul 12–18.
From 220 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 larva
Only 1 records here are marked as larvae, too few to show a larva season. One needs at least 20 records from 5 different years.
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.
Pole BorerNeandra brunneaOften confused in Ohio: 11 identifications in Ohio named one where the other was meant
Antelope BeetleDorcus parallelus27 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 August, middle week mid-July · 1,154 records
Reported as femaleUsually late June to late August, middle week mid-July · 61 records
Not every photo is marked with a sex or a sign, so these show when people reported each, not when it happens.

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.
