Reported as an adult
Usually reported as an adult late March to mid-November, middle week Aug 23–29.
From 1,131 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
Usually reported as a larva mid-May to mid-July, middle week mid-June, and again early August to late October, middle week mid-September.
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.
Polished Lady BeetleCycloneda mundaOften confused in Ohio: 92 identifications in Ohio named one where the other was meant
Seven-spotted Lady BeetleCoccinella septempunctataOften confused in Ohio: 58 identifications in Ohio named one where the other was meant
Convergent Lady BeetleHippodamia convergensOften confused in Ohio: 22 identifications in Ohio named one where the other was meant
Variegated Lady BeetleHippodamia variegataOften confused in Ohio: 18 identifications in Ohio named one where the other was meant
Swamp Milkweed Leaf BeetleLabidomera clivicollisOften confused in Ohio: 12 identifications in Ohio 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 recordsNo season shown · 5,823 records

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

From 3,603 records placed within 100 m, beside all Ohio records placed the same way. People record where they go, so this shows where records come from, not where the species lives. Land cover: USGS Annual NLCD, 2025 (opens in a new tab)
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.
