Season
When it is recorded
In Lake County
Not enough evidence
Recorded in two separate seasons, so one season would put its middle week in the gap. Based on 30 records in 8 of the 10 years from 2016 to 2025, above the minimum of 20 records from 5 different years.
Show over the bars
Records per week from 30 records in 8 of the 10 years from 2016 to 2025. Shows when people recorded it, not a season or how common it is.

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.
