Season
When it is recorded
In Ohio
Late May to early August, middle week Jun 28 – Jul 4
Records per week from 107 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 87 dates. Latest record: August 2025.

Reported as an adult
Only 13 records here are marked as adults, too few to show a adult season. One needs at least 20 records from 5 different years.
Reported as a larva
No records here are marked as larvae yet, so there is no larva season to show. 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.

Time of day it is recorded
From 105 Ohio records with a time. Most records are made when people are outside, so night and early-morning species are under-recorded.
